POLYTHIOPHENE DERIVATIVE, COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/127885
Kind Code:
A1
Abstract:
Disclosed are a polythiophene derivative, a composite material and preparation methods therefor, wherein the composite material is used in a substrate of quantum dots and organic light emitting diodes, and comprises a polythiophene derivative and an adulterant. The structural formula of the polythiophene derivative is formula I below, where R in formula I is selected form a linear alkane, branched alkane or branched aromatic hydrocarbon; and n in formula I represents the number of repeating units, and is a natural number from 1 to 5000. By means of the above-mentioned means, the present invention can alleviate color mixing caused by mixing of quantum dots or luminescent materials of different colors, and improve color purity.
