A dihydroxotin(IV) porphyrin functionalized single-walled carbon nanotubes (SWNTs) nanohybrid is obtained. Solubility of the nanohybrid in organic solvents is determined by UV-Vis-NIR absorption spectroscopy. Electron absorption and fluorescence spectra investigations demonstrate that efficient electron transfer occurs within the nanohybrid at the photoexcited state and the charge-separated state of the nanohybrid is observed by transient absorption spectrum. The results illustrate that this soluble electron donor-acceptor nanohybrid might be a good candidate as a light harvesting material in molecular photoelectronic devices.
获得了一种二羟基锡（IV）卟啉功能化的单壁碳纳米管（SWNTs）纳米杂化物。通过紫外-可见-近红外吸收光谱法测定该纳米杂化物在有机溶剂中的溶解度。电子吸收和荧光光谱研究表明，在光激发态下，纳米杂化物内部发生了有效的电子转移，并且通过瞬态吸收光谱观察到了纳米杂化物的电荷分离态。结果表明，这种可溶性电子供体-受体纳米杂化物可能是分子光电器件中光捕获材料的良好候选者。
