This invention relates to the field of organic photovoltaic (PV) device technology, specifically to an organic PV device based on disk-shaped liquid crystal molecules, its fabrication method, and its applications. The organic PV device based on disk-shaped liquid crystal molecules provided by this invention comprises an anode substrate, a hole transport layer, an active layer, an electron transport layer, and a metal cathode stacked sequentially. The active layer is composed of a donor material, an acceptor material, and a benzo[a]phenanthrene disk-shaped liquid crystal derivative. The benzo[a]phenanthrene disk-shaped liquid crystal derivative self-assembles into a two-dimensional columnar superlattice nanostructure. The benzo[a]phenanthrene disk-shaped liquid crystal derivative has the structure shown in Formula I and / or Formula II, where R1 and R2 independently comprise a cycloalkane-furanyl or adamantyl group. Based on the self-assembly behavior of the benzo[a]phenanthrene disk-shaped liquid crystal derivative, this invention constructs an ordered columnar superlattice structure by controlling its steric hindrance and dipole interactions, significantly improving the charge transport efficiency and energy conversion efficiency of the device.

This invention discloses an amino compound with a benzophenanthrene furan group and an organic light-emitting device, selected from compounds of formula 1: Al-A 10 One of the groups is derived from Formula 2, where * represents a bond connected to the basic skeleton in Formula 1. When A2 is derived from a group in Formula 2, L1 is a para-phenylene group, R1 and R2 are derived from single bonds, substituted or unsubstituted C5-C24 aromatic hydrocarbon groups, substituted or unsubstituted C5-C24 heteroaromatic hydrocarbon groups, and Ar1 and Ar2 are derived from C5-C30 aromatic hydrocarbon groups, substituted or unsubstituted C5-C30 heteroaromatic hydrocarbon groups. In this invention, the triarylamine is para-linked to a transition benzene ring with benzo[a]phenanthrenefuran. This benzene ring linkage enhances the overall stability of the target molecule, strengthens the conjugation of the molecule, and increases the stacking property of the molecule in organic light-emitting materials. This invention also sets phenanthrene, naphthyl, or dibenzothiophene groups on the other two substituents of the triarylamine, affecting the electron affinity and electron transport properties of the triarylamine and further extending its lifespan.
