In this paper, we report the synthesis and optoelectronic properties of a new anthracene-centered cruciform, 2,6-bis(9,9-di(2-ethylhexyl)fluorene-2-yl-vinyl-2)- 9,10-bis(9-(2-ethylhexyl)carbazole-3-yl-vinyl-2)anthracene (FCA). FCA was prepared by the Heck coupling 2,6-bis(diethoxylphosphorylmethyl)-9,10- dibromoanthracene and 9-(2-ethylhexyl)-3-vinylcabazole, followed by the Wittig–Horner reaction
在本文中,我们报告了一种以蒽为中心的新型十字形2,6-双(9,9-二(2-乙基己基)芴-2-基-乙烯基-2)-9,10-的合成和光电性能。双(9-(2-乙基己基)咔唑-3-基-乙烯基-2)蒽(FCA)。FCA的制备是通过Heck偶联2,6-双(二乙氧基磷酰基甲基)-9,10-二溴蒽和9-(2-乙基己基)-3-乙烯基咔唑,然后进行Wittig-Horner反应与9,9-di(2- (乙基己基)-2-甲酰基芴。强扭曲的9,10分支的存在使FCA表现出适度的聚集增强发射和压电荧光致变色,并且引入许多支链烷基链使FCA具有良好的溶解性和成膜能力。FCA 可以将其用作溶液处理的发光层,以提供峰值波长为612 nm的红色发射并且最大发光效率为1.3 cd / A。
