Abstract

The invention discloses a phenyl anthracene silole derivative organic optoelectronic material; with use of a catalytic action of a metallocene zirconium complex and butyl lithium on olefin polymerization, phenylsilane is synthesized through an anhydrous and anaerobic reaction; a silafluorene compound is synthesized by using CuCl catalytic action; with use of reduction of LiAlH4, an ester group is reduced into hydroxyl; the phenyl anthracene silole derivative organic optoelectronic material is synthesized by using DDQ oxidation. Compared with a general organic optoelectronic material, phenyl anthracene silole derivative parallel rings are increased, a pi-conjugated system is bigger, and the organic optoelectronic material has better electroluminescent properties in theory. In the synthesis process, o-bromo iodobenzene is used as a raw material, and silicon-bridged diyne is synthesized; zirconium induces a cycloaddition reaction for generating alkyne from silicon-bridged diyne, the conditions are easy to achieve, the time is short, and the yield is high. Compared with a conventional synthesis method of corresponding materials, the method adopts butyl lithium and the zirconocene complex for catalysis, has higher catalytic activity and yield, and has the used raw materials cheaper and easier to obtain.

Description

technical field [0001] The invention belongs to the field of chemistry and relates to an organic photoelectric material, in particular to an organic photoelectric material of benzene and anthrazosilole derivatives and a synthesis method thereof. Background technique [0002] Organic optoelectronic materials are a class of organic materials with optoelectronic activity, which are widely used in organic light-emitting diodes, organic transistors, organic solar cells, organic memories and other fields. The silole derivatives containing silicon heterocyclic rings have good redox stability due to their special structure, and they have relatively high hole transport rate and electron transport rate. However, the incorporation of benzene and naphthalene on both sides of silole, and the construction of silicon-bridged acene biphenyl by ring augmentation are difficult to solve in the synthesis. There are few reports on the synthesis of silafluorene molecules, and the synthesis method...
