采用拉曼光谱和原位拉曼光谱电化学研究了单壁碳纳米管（SWCNTs）与α-六噻吩（6 T）的相互作用。6 T在单壁碳纳米管中的包裹及其相互作用导致其光致发光的白化，以及其拉曼谱带的微小位移。与原始SWCNT相比，具有嵌入式6 T（6 T-peapod）的SWCNT的拉曼特征在强度和频率上都发生变化，这是共振条件变化的结果。电化学掺杂表明，施加到单壁碳纳米管壁的电极电位引起嵌入的6 T的变化。比较了电化学充电对原始单壁碳纳米管和6 T @ SWCNT的拉曼特征的影响。结果表明，单壁碳纳米管与6 T的相互作用也改变了单壁碳纳米管在其带电状态下的电子结构。这种电子结构的变化表现为半导体和金属管。
The interaction of single-walled carbon nanotubes (SWCNTs) and α-sexithiophene (6T) was studied by Raman spectroscopy and by in situ Raman spectroelectrochemistry. The encapsulation of 6T in SWCNT and its interaction causes a bleaching of its photoluminescence, and also small shifts of its Raman bands. The Raman features of the SWCNT with embedded 6T (6T-peapods) change in both intensity and frequency compared to those of pristine SWCNT, which is a consequence of a change of the resonant condition. Electrochemical doping demonstrated that the electrode potential applied to the SWCNT wall causes changes in the embedded 6T. The effects of electrochemical charging on the Raman features of pristine SWCNT and 6T@SWCNT were compared. It is shown that the interaction of SWCNT with 6T also changes the electronic structure of SWCNT in its charged state. This change of electronic structure is demonstrated both for semiconducting and metallic tubes.
