Organic photoelectric material containing ring-like urea structure and preparation method and application thereof

The invention relates to an organic photoelectric material containing a ring-like urea structure and a preparation method and application thereof. The structure of the organic photoelectric material is as shown in the general formula (I). In the general formula (I), A is selected from one of the following structural groups: R1-R3 are separately selected from any one of hydrogen, methyl, ethyl, C6-C30 polycyclic aromatic group conjugated structural group or C4-C30 polycyclic aromatic group conjugated structural group containing hetero atoms such as N, S, O, etc. The organic photoelectric material containing a ring-like urea structure is applied to a CPL layer of an organic light-emitting device. The organic photoelectric material containing the ring-like urea structure has high glass-transition temperature and molecular heat stability, has low absorption and high refractive index in the field of visible light, can help promote light extraction efficiency of an organic light-emitting device effectively after being applied to the CPL layer of the organic light-emitting device, and has a good application effect and industrial prospects.

ORGANIC COMPOUND, CHARGE-TRANSPORTING MATERIAL, COMPOSITION FOR CHARGE-TRANSPORTING MATERIAL AND ORGANIC ELECTROLUMINESCENT DEVICE

An organic compound having excellent heat resistance, an excellent amorphous nature, an excellent ability to transport charges, highly excited singlet and triplet states, and excellent solubility in an organic solvent is an organic compound represented by Formula (I): wherein Ar1 represents an optionally-substituted aromatic hydrocarbon group, an optionally-substituted aromatic heterocyclic group, or an optionally-substituted alkyl group; Ar2 represents an optionally-substituted aromatic hydrocarbon group or an optionally-substituted aromatic heterocyclic group; R1 and R2 each represent a hydrogen atom or a substituent, and R1 and R2 may be bonded to each other to form a ring; and Q is represented by Formula (I-1) or (I-2): wherein Ar3 to Ar5 each represent an optionally-substituted aromatic hydrocarbon group or an optionally-substituted aromatic heterocyclic group, and Ar3 and Ar4 may be bonded to each other to form a ring.
