摘　　要：酞菁的大π共轭体系使其具有良好的电子给予能力和对可见光的强烈吸收性质,可作为人工光合作用体系中的光捕捉单元.富勒烯具有独特的三维笼状结构,几乎所有反应中都具有低的重组能,是良好的电子或能量受体.将富勒烯与酞菁结合起来,集两个光活性实体于一身,由于酞菁和富勒烯给受体之间的电子相互作用,又赋予其新的性质,具有良好的应用前景,是富勒烯和酞菁领域中的研究热点.本文将酞菁-富勒烯给受体体系分为共价和非共价两种连接方式,介绍其结构与性质以及两者的相互关系,总结了其在有机太阳能电池、非线性光学和液晶性等方面的应用进展,展望了该体系的未来发展趋势.Phthalocyanine possesses strong electron-donating ability and visible light absorbing property due to the large n conjugated system, which makes it a good light-harvesting antenna for artificial photosynthetic systems. Meanwhile, the excellent electron-accepting property of fullerene C60, together with its lower organization energy, renders this spherical carbon cage a perfect acceptor for photo- and electroactive molecular systems. The combination of phthalocyanine and fullerene in one compound provides the system with new properties due to the interaction between the two photoactive moieties. As such, these systems display good application prospect and are hot topics in related research fields. In this review, the structures and properties of covalent and supramolecular noncovalent phthalocyanine-fullerene systems and their relationship are introduced. Moreover, the recent application progress of these systems in the fields of organic solar cell, nonlinear optics and liquid crystal property is summarized, and their future development trend is prospected.
