Two new perylene diimide molecules, 1, 7-bis(1-naphtyl)-N,N′-bis-(10-nonadecyl)-perylene-3,4,9,10-bis (dicarboximide) PDI-2 and 1,7-bis(5-acenaphtenyl)-N,N′-bis-(10-nonadecyl)-perylene-3,4,9,10-bis(dicarboximide) PDI-3 have been synthesized and used as acceptor components in P3HT/PDI bulk heterojunction solar cells. The introduction of fused aromatic rings into the bay positions of the perylene core creates
两个新的per二酰亚胺分子1、7-双(1-萘基)-N,N'-双-(10-十八烷基)-per-3,4,9,10-双(二甲叉酰亚胺)PDI-2和1,已合成7-双(5-ac烯基)-N,N'-双-(10-十八烷基)-per-3,4,9,10-双(二甲叉酰亚胺)PDI-3并用作P3HT / PDI体异质结太阳能电池。将稠合的芳环引入per核的海湾位置会产生强烈的空间位阻,扭曲the平面,直接影响相邻PDI之间的π-π分子内相互作用。所有这些特征有助于减少固态中的分子聚集,并对P3HT / PDI光伏器件的性能产生重大影响。
