合成了一系列含四噻吩、八噻吩和十二噻吩间隔基的卟啉-寡聚噻吩-富勒烯三元组。卟啉发色团在苯甲腈中的荧光通过电子转移到富勒烯部分而有效地猝灭。该过程显示低聚噻吩间隔基的弱距离依赖性，衰减因子β = 0.11 A（-1）。
A series of porphyrin-oligothiophene-fullerene triads containing quaterthiophene, octithiophene, and dodecithiophene spacers has been synthesized. The fluorescence of the porphyrin chromophore in benzonitrile is efficiently quenched by electron transfer to the fullerene moiety. This process shows a weak distance dependence of the oligothiophene spacer with an attenuation factor beta= 0.11 A(-1).
