在苯甲腈（PhCN）中，二氢卟酚羧酸锌（ZnCl 2-）与锂离子包覆的[60]富勒烯（Li+@C60）通过静电相互作用形成了电子给体-受体超分子配合物. ZnCl 2-/Li+@C60超分子复合物中的光诱导电子转移导致ZnCl 2-的三重激发态电子转移到Li+@C60形成电荷分离态。本文报道了使用ZnCl 2-/Li+@C60纳米团簇的光伏电池，其组装在纳米结构的SnO 2（OTE/SnO 2）的光学透明电极（OTE）上。ZnCl-和Li+@C60超分子团簇的纳米结构SnO 2薄膜（OTE/SnO 2/（ZnCl-/Li+@C60））的光电化学行为明显高于ZnCl-或Li+@C60单组分薄膜（OTE/SnO 2/（ZnCl-）或OTE/SnO 2/（Li+@C60）n）。
An electron donor–acceptor supramolecular complex was formed between an anionic zinc chlorin carboxylate (ZnCh-) and lithium-ion-encapsulated [60]fullerene (Li+@C60) by an electrostatic interaction in benzonitrile (PhCN). Photoinduced electron transfer in the supramolecular complex of ZnCh-/Li+@C60resulted in the formation of the charge-separated stateviaelectron transfer from the triplet excited state of ZnCh-to Li+@C60. We report herein photovoltaic cells using ZnCh-/Li+@C60nanoclusters, which are assembled on the optically transparent electrode (OTE) of nanostructured SnO2(OTE/SnO2). The photoelectrochemical behavior of the nanostructured SnO2film of supramolecular nanoclusters of ZnCh-and Li+@C60denoted as OTE/SnO2/(ZnCh-/Li+@C60)nis significantly higher than the single component films of ZnCh-or Li+@C60clusters, denoted as OTE/SnO2/(ZnCh-)nor OTE/SnO2/(Li+@C60)n.
