海湾处取代基的引入使 PDI 两个萘环之间由于空间张力的原因而发生螺旋形的扭曲
一、苝酰亚胺的研究
一、苝酰亚胺的研究
Photoinitiated Charge Transport in Supramolecular Assemblies of a 1,7,N,N’-Tetrakis(zinc porphyrin)-perylene-3,4:9,10-bis(dicarboximide), R. F. Kelley, W.-S. Shin, B. Rybtchinski , and M. R. Wasielewski, J. Am. Chem. Soc. 129, 3173-3181 (2007).
在甲苯溶液中, ZnTPP-PDI4 自组装形成具有五个分子的单分散聚集体( ZnTPP-PDI4)5, ZnTPP-PDI 不会形成聚集体, ( ZnTPP-PDI4)5 形成 4.8ns的电荷分离态, ZnTPP-PDI 形成3.0ns 的电荷分离态。
