Problems solved by technology

However, conventional organic light-emitting materials such as those described above have the following problems: due to concentration extinction due to intermolecular interactions, a decrease in luminous luminance is seen, and sufficient luminous luminance and luminous efficiency cannot be obtained.
However, regarding the luminescent properties of such an organic-inorganic composite material, there has been no report that it has been studied, and there is no report that suggests making it a luminescent material

Embodiment 1

[0220] In a mixture of ion-exchanged water (500g) and 6 equivalents of NaOH aqueous solution (40g, 200mmol NaOH), make octadecyltrimethylammonium chloride (ODTMA, [C 18 h 37 N(CH 3 ) 3 Cl], manufactured by Tokyo Chemical Industry) (16.665g, 47.88mmol) was dissolved. While stirring vigorously at room temperature, 1,4-bis(triethoxysilyl)benzene (BTEB, manufactured by Azmax) (20 g, 49.67 mmol) was added to the solution. The mixture was placed in a sonicator for 20 minutes to disperse the separated hydrophobic BTEB in the aqueous solution, and the stirring was continued at room temperature for 20 hours. The solution was left to stand in an oil bath at 95°C for 20 hours. The generated white precipitate was filtered and dried to obtain a precursor (8.22 g) of a mesoporous body containing a surfactant. 1 g of the precursor was dispersed in ethanol (250 ml) to which 9 g of 36% HCl aqueous solution was added, and heated and stirred at 70° C. for 8 hours, whereby the surfactant in ...

Embodiment 2

[0222] A mixed solution of 50 g of water and 4 g of NaOH was stirred, and 2 g of BTEB was quickly added thereto. Thereafter, ultrasonic waves were applied thereto for 20 minutes. At this point, the solution became cloudy. Then, stirring at room temperature for 24 hours turned into a translucent liquid. Thereafter, it was left still at 98° C. under reflux for 20 hours. After the temperature was raised, the solution began to appear white turbid, and then a precipitate was gradually formed. This precipitate was filtered and dried at room temperature to obtain a white powdery benzene silica composite material (Ph-Si).

Embodiment 3

[0224] triblock copolymer of poly(ethylene oxide) 20 - Poly(propylene oxide) 70 - Poly(ethylene oxide) 20 (poly(ethylene oxide) 20 -poly(propylene oxide) 70 -poly(ethylene oxide) 20 ); (P123: Mav=5800) A product manufactured by Aldrich was used. 0.99 g of P123 was dissolved in 36 ml of ion-exchanged water, and then 200 ml of hydrochloric acid (36 wt%) was added. After adding 1.01 g of BTEB to this solution at 0° C. (in a water bath), and stirring for 1 hour, it was heated and stirred at 35° C. for 20 hours. It was moved into an airtight container and heated at 100°C for an additional 24 hours. After cooling to room temperature, it was filtered, washed, and dried to obtain a precursor of a mesoporous body containing a surfactant. The precursor was dispersed in 60 times the weight of ethanol, stirred for more than 1 hour, then filtered, dried, and then fired at 350° C. in air for 2 hours, thus obtaining 0.3 g of benzene silica composite material. Mesoporous body (Ph-HMM-...

Abstract

Disclosed is a luminescent material composed of an organosilicon compound polymer represented by the following general formula (1):[wherein X represents a fluorescent or phosphorescent organic molecule; R<1> represents a lower alkoxy group, hydroxyl group, allyl group, ester group or halogen atom; R<2> represents a lower alkyl group or hydrogen atom; n represents an integer of 1-3; and m represents an integer of 1-4].

Description

technical field [0001] The present invention relates to a luminescent material and a manufacturing method thereof, more specifically, to an organic luminescent material containing organic molecules showing fluorescence or phosphorescence and a manufacturing method thereof. Background technique [0002] In the past, organic light-emitting materials can be classified into low-molecular-weight and high-molecular-weight. The former low-molecular-weight light-emitting materials include aromatic fluorescent pigments such as anthracene, benzene, and biphenyl, aluminum complexes, iridium complexes, and so on. Complexes of substances, rare earths, etc.; as the latter polymer light-emitting materials, there are polyphenylene vinylenes, polyfluorenes, polythiophenes, non-conjugated polymers containing pigments, etc. {for example, refer to Document 1 , Kazuyuki Horie et al. "Optofunctional Molecule Science-Molecular Photonics One", issued by Kodansha, August 10, 2001, the 7th printing a...
