摘要
碳纳米管是具有一维纳米结构的新型纳米材料,具有许多独特的物理、化学性质.卟啉对可见光具有强烈吸收,其大π共轭体系使其具有良好的电子给予能力,可作为人工光合作用体系的光捕捉单元.将具有电子接受能力的碳纳米管与卟啉结合起来,通过卟啉对碳纳米管进行共价和非共价修饰,可以改善碳纳米管在溶剂中的溶解分散性能,同时实现卟啉和碳纳米管之间有效的电子传递,形成具有独特光电和光学性质卟啉-碳纳米管复合物.该类物质具备良好的应用前景,是碳纳米管和卟啉研究中的热点.就近年来该类复合物的构筑方法及性质研究等方面的进展进行了综述.
Carbon nanotubes are novel nano-materials with one-dimentional nanostructure.They have many unique physical and chemical properties.Porphyrin has strong absorption in visabal light region.The large π conjugated system made it a good electron donor and light harvest unit for artifical photosynthetic systems.The combination of electron donor carbon nanotubes with porphyrin and the covalent and non-covalent porphyrin modification of carbon nanotubes can improve solubility and dispersibility of carbon nanotubes in solvent and carry out effective electron transfer between them to form porphyrin-carbon nanotube hybrid systems with unique photoelectric and optical properties.These kind of hybrid systems have a good application prospect and are hot point in related research fields.In this review,recent progress of the construction and properties of these hybrid systems is summarized.
