Polycyclic aromatic compound, material for organic device, organic electroluminescent element, display device, and lighting device

The invention provides a polycyclic aromatic compound, a material for organic devices, an organic electroluminescent element, a display device, and a lighting device. The polycyclic aromatic compound has a structure composed of one or more structural units represented by formula (1); the C ring has a structure represented by formula (1C-A) or formula (1C-B), # B represents a bonding position with boron, # N represents a bonding position with nitrogen, Ra1 to Ra3, Rb1 to Rb4, Rc1 to Rc4 and Rc11-Rc14 are hydrogen or a substituent, A is > O, > C (-CH3) 2 or > S, Ar1 and Ar2 are groups represented by formula (Ar), Rg1 to Rg8 are hydrogen or a substituent, X is a substituted or unsubstituted aryl group, and X is a substituted or unsubstituted aryl group. In the structure, at least one selected from a group consisting of an aryl ring and a heteroaryl ring can be condensed by at least one cycloalkane, and at least one hydrogen can be substituted by deuterium. # imgabs0 # 本发明提供一种多环芳香族化合物、有机器件用材料、有机电致发光元件、显示装置及照明装置。多
