本文根据近年来的研究结果，综述了富勒烯与供电子分子和受电子分子杂化的光敏电子转移过程。富勒烯作为光敏电子受体相对于各种各样的电子供体;此外，富勒烯在基态也作为良好的电子受体在光吸收电子供体如卟啉的存在下。对于单壁碳纳米管（SWCNT），光激发的富勒烯充当电子受体。在三重富勒烯/卟啉/单壁碳纳米管架构的情况下，光激发的卟啉作为电子供体朝向富勒烯和单壁碳纳米管。这些机制是合理的与这些巨大的超分子进行分子轨道的考虑。为了确认的电子转移过程中，瞬态吸收方法已被使用，除了时间分辨荧光光谱测量。在溶液中获得的动力学数据被发现是相当有用的预测光伏电池的效率。
Photosensitized electron-transfer processes of fullerenes hybridized with electron donating or other electron accepting molecules have been surveyed in this review on the basis of the recent results reported mainly from our laboratories. Fullerenes act as photo-sensitizing electron acceptors with respect to a wide variety of electron donors; in addition, fullerenes in the ground state also act as good electron acceptors in the presence of light-absorbing electron donors such as porphyrins. With single-wall carbon nanotubes (SWCNTs), the photoexcited fullerenes act as electron acceptor. In the case of triple fullerene/porphyrin/SWCNT architectures, the photoexcited porphyrins act as electron donors toward the fullerene and SWCNT. These mechanisms are rationalized with the molecular orbital considerations performed for these huge supramolecules. For the confirmation of the electron transfer processes, transient absorption methods have been used, in addition to time-resolved fluorescence spectral measurements. The kinetic data obtained in solution are found to be quite useful to predict the efficiencies of photovoltaic cells.
