A donor−acceptor dyad system involving tetrathiafulvalene (TTF) as donor attached by a flexible spacer to perylene-3,4:9,10-bis(dicarboximide) (PDI) as acceptor was synthesized and characterized. The strategy used the preliminary synthesis of an unsymmetrical PDI unit bearing an alcohol functionality as anchor group. Single-crystal analysis revealed a highly organized arrangement in which all PDI molecules
合成并表征了一个供体-受体二元体系,该体系包含四硫富瓦烯(TTF)作为供体,通过柔性间隔基连接到to-3,4:9,10-双(二甲叉酰亚胺)(PDI)作为受体。该策略使用具有醇官能团作为锚定基团的不对称PDI单元的初步合成。单晶分析揭示了一种高度组织化的排列,其中所有PDI分子都以非中心对称模式堆积。结果表明,TTF-PDI dyad的荧光发射强度可以根据TTF单元的氧化态进行可逆调节。此行为归因于与PDI受体连接的TTF的特殊属性,该属性固有地发出荧光。因此,该二元组可以被认为是一种新的可逆的荧光-氧化还原依赖性分子系统。
