Abstract

A process for syntheszing PPV luminous polymer which contains symbenzene center includes such steps as 1. synthesizing center monomer by inducting multitude functional group structure center substance which contains two or many symbenzene or be similar to A, B, C, D, E, F; the compound is skewness conjugation ring; 2. Selecting and synthesizing side chain monomer; 3. synthesizing the polymer by taking reaction A, B, C, D, E, F with side chain monomer H separately to get polymers of styrene with two or many symbenzene center.

Description

technical field

[0001] The invention relates to a PPV polymer, in particular to a PPV luminescent polymer containing a biphenyl center. Background technique

[0002] π-conjugated organic polymers have aroused great interest among scientists due to their broad application prospects in electron conduction, nonlinear optics, electronics and optoelectronics. In particular, the application of light-emitting substances in organic light-emitting diodes has been deeply studied. As the basic materials of organic light-emitting diodes, they have the following advantages: relatively simple preparation method; adjustability of emission color. The oligomer, which is the model compound of the corresponding polymer, can not only provide us with the microstructure information of the corresponding polymer system, but also can be used as an active substance for various scientific researches. Benefiting from the certainty of the oligomer structure, its conjugation length has a single distrib...
