Abstract
Description
Ink-repellent compound and photosensitive composition containing the same
[0001] The present invention relates to an ink-repellent compound and a photosensitive composition comprising the same.
[0002] In the manufacture of optical devices such as organic EL (Electro-Luminescence) devices, quantum dot displays, TFT (Thin Film Transistor) arrays, and thin film solar cells, the inkjet (IJ) method, which forms organic layers such as light-emitting layers into dots using an inkjet head, has been used as one of the methods for implementing patterns.
[0003] The inkjet method has the advantage of reducing material costs because it uses only the necessary amount of material for the necessary area, and in particular, it has the advantage of being able to form color filters, light-emitting layers, etc. of organic EL (Electro-Luminescence) devices or quantum dot displays by turning quantum dot materials, which are difficult to deposit, into ink.
[0004] This inkjet method is a method of forming dots in a desired pattern by injecting ink containing quantum dot material or organic layer material into a compartment surrounded by a partition wall and drying and / or heating the ink.
[0005] When printing a pattern using an inkjet method, the partitions formed along the outline of the dot need to have ink repellency to prevent mixing of ink between adjacent dots and to ensure uniform application of ink when forming dots.
[0006] To this end, a process for forming partition walls corresponding to the dot pattern by photolithography using a photosensitive composition exhibiting ink repellency is being developed, and there is a need for the development of a photosensitive composition with excellent ink repellency, developability, and good adhesion.
[0007] One embodiment of the present invention provides a photosensitive resin composition capable of controlling defects such as the coffee-ring phenomenon when manufacturing a light-emitting element and a color filter using a solution process by providing an ink-repellent compound and a photosensitive composition having low surface tension including the same.

[0155] The term "ring assemblies" as used herein means two or more ring systems (single ring or fused ring systems) directly connected to each other via single or double bonds, wherein the number of such direct links between rings is one less than the total number of ring systems in the compound. Ring assemblies may be formed by the same or different ring systems being directly connected to each other via single or double bonds.
[0156] In the present application, since the aryl group includes a ring aggregate, the aryl group includes biphenyl and terphenyl in which a single aromatic ring, a benzene ring, is connected by a single bond. In addition, the aryl group also includes a compound in which an aromatic single ring and an aromatic ring system fused together are connected by a single bond, and thus, for example, the aryl group also includes a compound in which an aromatic single ring, a benzene ring, and an aromatic ring system fused together, a fluorene ring, are connected by a single bond.

[0158] The term "spiro compound" used in this application has a "spiro union," which means a connection formed by two rings sharing only one atom. In this case, the atom shared between the two rings is called a "spiro atom," and depending on the number of spiro atoms contained in a compound, these are called "monospiro-," "dicepiro-," and "trispiro-" compounds, respectively.
[0159] As used herein, the terms "fluorenyl group", "fluorenylene group", and "fluorenetriyl group" mean, unless otherwise stated, a monovalent, divalent, or trivalent functional group in which R, R', R", and R'" in the following structures are all hydrogen, and a "substituted fluorenyl group", a "substituted fluorenylene group", or a "substituted fluorenetriyl group" means that at least one of the substituents R, R', R", and R'" is a substituent other than hydrogen, and includes a case where R and R' are bonded to each other to form a spiro compound together with the carbon to which they are bonded.

[0162] The term "heterocyclic group" used in this application includes not only aromatic rings such as "heteroaryl group" or "heteroarylene group" but also non-aromatic rings, and unless otherwise stated means a ring having 2 to 60 carbon atoms each containing one or more heteroatoms, but is not limited thereto. The term "heteroatom" used in this application represents N, O, S, P or Si unless otherwise stated, and the heterocyclic group means a monocyclic ring, ring aggregate, fused multiple ring system, spiro compound, etc. containing a heteroatom.
[0163] For example, “heterocyclic group” may also include compounds that contain heteroatom groups such as SO2, P=O, etc. instead of ring-forming carbon, such as the compounds below.
[0164]
[0165] The term "ring" as used in this application includes monocyclic and polycyclic rings, and includes hydrocarbon rings as well as heterocyclic rings containing at least one heteroatom, and includes aromatic and non-aromatic rings.
[0166] The term "polycyclic" as used in this application includes ring assemblies such as biphenyls, terphenyls, etc., fused multiple ring systems and spiro compounds, including aromatic as well as non-aromatic, and including hydrocarbon rings as well as heterocycles containing at least one heteroatom.
[0167] The term "aliphatic ring" used in this application refers to a cyclic hydrocarbon other than an aromatic hydrocarbon, and includes a single ring, a ring aggregate, a fused multiple ring system, a spiro compound, etc., and unless otherwise specified, refers to a ring having 3 to 60 carbon atoms, but is not limited thereto. For example, even if an aromatic ring, benzene, and a non-aromatic ring, cyclohexane, are fused, it is considered an aliphatic ring.
[0168] Also, when prefixes are named consecutively, it means that the substituents are listed in the order they were first written. For example, in the case of an arylalkoxy group, it means an alkoxy group substituted with an aryl group, in the case of an alkoxycarbonyl group, it means a carbonyl group substituted with an alkoxy group, and in the case of an arylcarbonylalkenyl group, it means an alkenyl group substituted with an arylcarbonyl group, where the arylcarbonyl group is a carbonyl group substituted with an aryl group.
[0169] Also, unless explicitly stated otherwise, the term "substituted" in the term "substituted or unsubstituted" used in this application means deuterium, halogen, amino group, nitrile group, nitro group, C1~C 30 Alkyl group of C1~C 30 Alkoxy group, C1~C 30 Alkylamine group of C1~C 30 Alkylthiophene group, C6~C 30 Arylthiophene group, C2~C 30 Alkenyl group, C2~C 30 Alkyne group, C3~C 30 Cycloalkyl group, C6~C 30 Aryl group of C6~C substituted with deuterium 30 Aryl group of C8~C 30 C2~C containing at least one heteroatom selected from the group consisting of arylalkenyl group, silane group, boron group, germanium group, and O, N, S, Si and P 30 It means that it is substituted with one or more substituents selected from the group consisting of heterocyclic groups, but is not limited to these substituents.
[0170] In this application, the 'functional group name' corresponding to the aryl group, arylene group, heterocyclic group, etc., which are exemplified as examples of each symbol and its substituent, may be described as the 'name of the functional group reflecting the valence', but may also be described as the 'name of the parent compound'. For example, in the case of 'phenanthrene', which is a type of aryl group, the name of the group may be described by distinguishing the valence, such as 'phenanthryl (group)' for the monovalent 'group' and 'phenantrylene (group)' for the divalent group, but the name of the parent compound, 'phenanthrene', may also be described regardless of the valence.
[0171] Similarly, in the case of pyrimidine, regardless of the valence, it can be written as 'pyrimidine', or in the case of monovalent, it can be written as pyrimidinyl (group), in the case of divalent, it can be written as the 'group name' of the corresponding valence, such as pyrimidinylene (group). Accordingly, in the present application, when the type of substituent is written as the name of the parent compound, it can mean an n-valent 'group' formed by the elimination of a hydrogen atom bonded to a carbon atom and / or heteroatom of the parent compound.
[0172] In addition, in this specification, numbers or alphabets indicating positions may be omitted when describing compound names or substituent names. For example, pyrido[4,3-d]pyrimidine may be described as pyridopyrimidine, benzofuro[2,3-d]pyrimidine as benzofuropyrimidine, 9,9-dimethyl-9H-fluorene as dimethylfluorene, etc. Accordingly, both benzo[g]quinoxaline and benzo[f]quinoxaline may be described as benzoquinoxaline.
[0173] Additionally, unless explicitly stated otherwise, the chemical formulas used in this application are applied in the same manner as the substituent definitions by the index definitions of the chemical formulas below.
[0174]
[0175] Here, if a is an integer of 0, the substituent R 1means that it is absent, that is, when a is 0, it means that all the carbons forming the benzene ring are bonded with hydrogen, and in this case, the indication of hydrogen bonded to carbon can be omitted and the chemical formula or compound can be described. In addition, when a is an integer of 1, one substituent R 1 It binds to one of the carbons forming the benzene ring, and when a is an integer of 2 or 3, it can bind as follows, for example, and when a is an integer of 4 to 6, it binds to the carbon of the benzene ring in a similar manner, and when a is an integer of 2 or more, R 1 may be the same or different.
[0176]
[0177] Unless otherwise stated in this application, forming a ring means that adjacent groups are bonded to each other to form a single ring or a fused multiple ring, and the single ring and the formed fused multiple ring include a hydrocarbon ring as well as a heterocycle containing at least one heteroatom, and may include aromatic and non-aromatic rings.
[0178] Additionally, unless otherwise stated herein, when indicating a condensed ring, the number in the expression "number-condensed ring" indicates the number of condensed rings. For example, a form in which three rings are condensed together, such as anthracene, phenanthrene, and benzoquinazoline, can be expressed as a 3-condensed ring.
[0179] Meanwhile, the term "bridged bicyclic compound" used in this application, unless otherwise specified, refers to a compound in which two rings share three or more atoms to form a ring. The shared atoms may include carbon or heteroatoms.
[0180] In the present application, the liquid-repellent treatment step may be a step of treating with a gas containing a halogen atom, and additionally containing one or more of an inert gas, a hydrocarbon, oxygen, or carbon dioxide. Liquid-repellent properties are imparted to the film-forming surface through deposition of the gas applied in this step. The deposition of the applied gas may utilize a plasma method, and the inert gas can stabilize the plasma state of the gas, thereby more uniformly imparting liquid-repellent properties to the film-forming surface.
[0181] In the present application, the organic electric element may mean a component(s) between an anode and a cathode, or may mean an organic light-emitting diode including an anode and a cathode and a component(s) positioned therebetween.
[0182] In addition, in some cases, the display device in the present application may mean an organic electroluminescent element, an organic light-emitting diode, and a panel including the same, or may mean an electronic device including a panel and a circuit. Here, for example, the electronic device may include a lighting device, a solar cell, a portable or mobile terminal (e.g., a smart phone, a tablet, a PDA, an electronic dictionary, a PMP, etc.), a navigation terminal, a game machine, various TVs, various computer monitors, etc., and is not limited thereto, and may be any type of device as long as it includes the above-mentioned component(s).
[0183] Hereinafter, embodiments of the present invention will be described in detail. However, these are presented as examples and are not intended to limit the present invention. The present invention is defined solely by the scope of the claims set forth below.
[0184] A composition comprising a colorant according to one embodiment of the present invention can be used to manufacture a red pattern, a green pattern, a blue pattern, or a black matrix, a pixel definition layer (PDL).
[0185] A black pixel definition layer (PDL) according to one embodiment of the present invention may further include an organic black pigment or black dye as an additional coloring agent other than the coloring agent included in the aforementioned coloring agent. For example, an organic pigment may be used alone, or an organic pigment and a coloring pigment may be mixed and used. In this case, since a coloring pigment with insufficient light-blocking properties is mixed, there is an advantage in that the strength of the film (layer) or the adhesion to the substrate is not reduced even if the amount of the coloring agent is relatively increased. A negative pixel definition layer (PDL) according to one embodiment of the present invention may include a black pigment or black dye as an additional coloring agent instead of the coloring agent included in the aforementioned coloring agent.
[0186] Each component is described in detail below.
[0187] 1. The manufacturing process of the negative pixel definition layer is as follows.
[0188] (1) Application and coating stage
[0189] The photosensitive composition is a low-viscosity liquid sample, and a spin coater or slit coater is used to coat the substrate to a certain thickness after application. The spin coater has the advantage of reducing the thickness as the rotation speed increases, but the flatness deviation in the area is reduced, and a slit coater is preferable to a spin coater for coating a large-area substrate. The solvent remaining after coating causes the surface to be fluid, which has the disadvantage of deteriorating flatness. To overcome this, VCD (vacuum chamber dry) is used to remove some of the solvent, thereby reducing the fluidity on the surface.
[0190] (2) Prebaking stage
[0191] This process involves heating the coated substrate at a specified temperature and time using a hot plate or oven to remove some of the solvent contained in the coating film. If the surface or deep portion of the coating film does not dry, photomask contamination may occur during exposure in the next process, and curing may not occur properly in the exposed area when exposed to UV light. Due to this lack of curing, the pattern is not formed and is removed during the development process.
[0192] (3) Exposure stage
[0193] After the above pre-baking process is completed, this is the process of curing the formed film by irradiating the photomask with an active line (ultraviolet rays) on which a pattern has been formed. The types of lamps that generate the active line include LED lamps and metal (mercury) lamps, and the wavelengths include g-line (436 nm), h-line (405 nm), i-line (365 nm), and deep UV (<260 nm), and they can be used individually or in combination.
[0194] (4) Phenomenon stage
[0195] In the above exposure step, when the active line is irradiated, the exposed part and the non-exposed part are divided by the photomask. In the case of the positive type, the exposed part is dissolved by the developer, and the non-exposed part resists the developer and a pattern remains. In the case of the negative type, the exposed part is hardened and has resistance to the developer, and the non-exposed part is developed. The black pixel definition layer (Black PDL) manufactured with the composition including the coloring agent of the present invention is divided into an exposed part (hardened) and a non-exposed part (developed) in the negative type, and a pattern is formed.
[0196] 2. The composition forming a negative pixel definition layer including a coloring agent is as follows.
