Single wall carbon nanotubes (SWNTs) bind strongly to sapphyrins, quintessential pentapyrrolic "expanded porphyrin" macrocycles, through donor-acceptor stacking interactions. The specific use of a functionalized sapphyrin diol yields stable water-suspendable nanotubes and also permits the formation of well-defined assemblies in ionic liquids. The absorption and steady-state fluorescence spectra of the resulting noncovalently functionalized nanotube complexes have been analyzed in aqueous media and ionic liquids, yielding a description of the photophysical properties of the nanotube-sapphyrin complexes as donor-acceptor species for light-harvesting.
单壁碳纳米管（SWNTs）通过供体-受体堆积相互作用与卟啉（典型的五吡咯“扩展卟啉”大环）强烈结合。使用功能化的卟啉二醇可产生稳定的水悬浮纳米管，还能在离子液体中形成结构明确的组装体。已在水性介质和离子液体中分析了所得非共价功能化纳米管复合物的吸收光谱和稳态荧光光谱，从而描述了纳米管-卟啉复合物作为光捕获供体-受体物种的光物理性质。
