The following exemplary embodiments are used to illustrate the present invention, but not to limit the scope of the present invention.
[0036] Explanation of terms in this manual:
[0037] "Substituted or unsubstituted" means unsubstituted or substituted with one or more substituents selected from the group consisting of deuterium, halo, nitrile, nitro, hydroxyl, carbonyl, ester, acyl Amino, amino, phosphineoxide, alkoxy, aryloxy, alkylthio, arylthio, alkylsulfonyl, arylsulfonyl, silyl, boryl, alkyl, cycloalkane group, alkenyl, aryl, aralkyl, aralkenyl, alkylaryl, alkylamine, aralkylamine, heteroarylamine, arylamine, arylphosphino; and hetero The cyclic group is either unsubstituted or substituted with a substituent in which two or more of the substituents exemplified above are connected. For...
Synthetic example
[0313] The reaction formula refers to an example in which a specific substituent is introduced, but if necessary, those skilled in the art can introduce the substituent without using techniques known in the art, and when introducing the substituent, the introduction can be performed by changing the kind of the substituent or Quantity to do. In addition, those skilled in the art can introduce by changing the samples, reaction conditions or starting materials of the following reaction formulas using techniques known in the art.
[0314] For example, the compound represented by the general formula 1 has an intermediate unit according to the following synthesis method.
Synthetic example 1
[0315] Synthesis of the following intermediates A-1, B-1, C-1, D-1, E-1, and F-1. The qualifier for Y is the same as in Formula 1.

A main functional unit of the compound shown in the general formula (1) realizes intramolecular interaction through spatial non-conjugated connection, and the material has excellent luminescence property and can be used as a material of an organic material layer of an organic light-emitting device, especiallya material of a core light-emitting layer.
Description
technical field [0001] The invention relates to a compound, an organic electronic device containing the same, and a display device or lighting device, belonging to the technical field of organic electronics. Background technique [0002] An organic electronic device is typically represented by an organic light emitting device, and a typical example of the organic light emitting device is an organic light emitting diode (Organic Light Emitting Diode, OLED for short). An organic light-emitting diode is a current-driven light-emitting device that uses organic materials as active materials. Specifically, it refers to the technology in which organic semiconductor materials and organic light-emitting materials are driven by an electric field to cause light emission through carrier injection and recombination. Unlike inorganic materials, organic materials have the characteristics of low synthesis cost, adjustable function, flexibility, and good film-forming properties. Moreover, d...
