QUINOXALINE CONJUGATED POLYMER CONTAINING FUSED-RING THIOPHEHE UNIT, PREPARATION METHOD AND USES THEREOF

摘要

A quinoxaline conjugated polymer containing fused-ring thiophene unit is disclosed, and the general formula of molecular structure thereof is formula (I). In the formula, x+y=2, 1≤ x 2, n is an integer and 1 n≤ 100, R1, R2 are selected from C1∼C20 alkyl, R3, R4 are selected from -H, C1∼C20 alkyl, C1∼C20 alkoxy, benzene ring group containing alkyl or alkoxy, fluorene group containing alkyl or carbazole group containing alkyl. The polymer is useful in the fields of solar battery and the like.
