HOLE TRANSPORTING LAYER CONTAINING ORGANIC CONJUGATED POLYMER SEMICONDUCTOR MATERIAL AND USE THEREOF

WIPO Patent Application WO/2019/006852

A1

The present disclosure discloses a hole transporting layer containing an organic conjugated polymer semiconductor material and a use thereof. The repeating unit of the main chain of the organic conjugated polymer semiconductor material is composed of a p-alkoxybenzene unit and an aromatic ring unit. The organic conjugated polymer has the following structural formula (I): wherein R1 and R2 are independently selected from one or a combination of at least two of a C1 to C20 alkyl group, and Ar is an aromatic ring group. The present disclosure uses a p-alkoxybenzene B (bisOR) to construct a polymer, which simplifies the structure and synthesis of a conjugated polymer-based hole transporting material and can reduce costs. The high degree of planarity of the B (bisOR) derivative unit itself and the weak steric hindrance between it and the adjacent units are conducive to the hole transport. In addition, a polymer containing a B (bisOR) unit also possesses an appropriate energy level relative to the perovskite material, thereby facilitating the collection of photogenerated holes and preventing the recombination of photogenerated electrons.
