摘要：
Disclosed are styryl dyes of formulawhereinR1, R2, R3, R′1, R′2 and R′3 independently of each other are hydrogen； —NH(CO)—C1-C5alkyl； —N(C1-C5alkyl)(C1-C5alkyl-CN)； C1-C6alkoxy； a heterocyclic radical； or R1 and R2 or R′1 and R′2 together form a 5- to 10-membered, monocyclic, carbocyclic or heterocyclic ring； wherein at least one of R1, R2, R3, R′1, R′2 and R′3 is different from hydrogen；Q and Q′ independently from each other are the direct bond； *—C(O)—*； *—C(O)O—*； *—OCO—*； *—N(R4)—*；*—C(O)N(R6)—*； or *—(R6)NC(O)—*； andR4, R5 and R6 independently from each other are hydrogen； C1-C14alkyl； C2-C14alkenyl； C6-C12aryl； C6-C12aryl-C1-C10alkyl； or C1-C10alkyl(C5-C12aryl)；X and X′ are *—(CH2)m—*；Y1 and Y2 independently from each other are C1-C10alkylene； C5-C10cycloalkylene； C5-C12arylene； or C5-C12arylene-(C1-C10alkylene)；An− is an anion；m is a number from 1 to 8；n is 0, or 1； andp is 0, or 1.
