Abstract In this review, noncovalent functionalization of single-wall carbon nanotubes (SWCNTs) is briefly reviewed. The functional materials summarized here include metalloporphyrin derivatives, biomolecules and conjugated polymers. Notably, time-resolved spectroscopic techniques such as time-resolved fluorescence and transient absorption were employed to directly investigate the electron transfer and recombination processes between the functionalities and the SWCNTs. In addition, Raman spectroscopy is also useful to identify the interaction and the electron transfer direction between both the functionalities and the SWCNTs. An improved understanding of the mechanisms of these SWCNT-based nanohybrids in terms of their structural and photophysical properties can provide more insights into the design of new electronic materials.

基于单壁碳纳米管 (SWCNT) 的杂化物的光致电子转移过程

摘要 在这篇综述中，简要回顾了单壁碳纳米管 (SWCNT) 的非共价功能化。这里总结的功能材料包括金属卟啉衍生物、生物分子和共轭聚合物。值得注意的是，时间分辨光谱技术，如时间分辨荧光和瞬态吸收，被用来直接研究功能和 SWCNT 之间的电子转移和复合过程。此外，拉曼光谱还可用于识别功能和 SWCNT 之间的相互作用和电子转移方向。更好地了解这些基于 SWCNT 的纳米杂化物在其结构和光物理特性方面的机制，可以为新电子材料的设计提供更多见解。
