metathesis polymerization. The optical and electrochemical properties of the new polymers, both in the soluble and crosslinked forms, are reported. These polymers are used in the preparation of organic photovoltaics upon blending with PCBM as electron‐acceptor. The effect of the crosslinking of these copolymers, once the blend films are formed, on the devices performance is also studied. In particular, the
使用格利雅(Grignard)复分解聚合反应合成了几种含有3-己基噻吩区域规则链段的可交联氧杂环丁烷官能化共聚物。据报道,新聚合物的光学和电化学性质均为可溶和交联形式。这些聚合物与PCBM作为电子受体共混后,可用于制备有机光伏电池。一旦共混膜形成,这些共聚物的交联对器件性能的影响也将被研究。特别是,氧杂环丁烷官能化的噻吩共聚单体的插入会导致器件性能下降,在共聚物交联时会进一步降低。然而,装置的稳定性在共聚物交联时总体上得到改善。©2013 Wiley Periodicals,Inc. J. Polym。科学,A部分:Polym。化学2014,52,652-663
