锌卟啉-富勒烯配合物的光谱和光伏性质研究

Spectral and photovoltaic properties of zinc porphyrin-fullerene

采用光谱法研究了不同电子取代基的锌卟啉-富勒烯配合物[ZnP-C60和(p-OCH3)ZnP-C60]的光谱性质。结果表明,与ZnP-C60相比,含甲氧基修饰的锌卟啉-富勒烯(p-OCH3)ZnP-C60的紫外-可见吸收光谱和荧光光谱发射谱带均发生红移。以氙灯作光源,利用三电极光化学电池系统研究了两者在O2/H2O、I2/I-3、Fe(CN)3-6/Fe(CN)4-6和BQ(苯醌)/H2Q(氢醌)四种介质中的的光伏性质。结果显示,(p-OCH3)ZnP-C60具有优良的光伏性能,尤其在O2/H2O介质电对中,光生电压最大为215 mV。

The spectral properties of ZnP-C60and （p-OCH3 ）ZnP-C60 with different electronic groups were studied by spec- trometry. The red-shift of UV-vis absorption and fluorescence spectra from （p-OCH3 ） ZnP-C60 was described. And then the photo- voltaic property was investigated by the photochemic.,fl cell with a three-electrode system in O2/H2O, I2/I3-, Fe （CN） 36--/Fe （CN）4 6- , BQ/H2Q redox couple. The result of photovoltaic effect （PVE） indicated that excellent photoelectric property of （p- OCH3 ）ZnP-C60 is obtained , especially w in the O2/H20 redox couple, and the greatest value of photovoltaie potential is 215 mV.
