PVK-Modified Single-Walled Carbon Nanotubes with Effective Photoinduced Electron Transfer

Abstract

SWNTs are among the most attractive one-dimen-sional materials in the scientific world. Recently, con-siderable work has been done to modify SWNTs in order to bring these fascinating carbon structures into the fold of (macro)molecular chemistry and to endow SWNTs with ultimate new characteristics.1 The polymer wrap-ping of SWNTs has been proved to be an effective supramolecular approach to modify SWNTs.2 Certain polymers could also be bound to the SWNT surface covalently through the defect sites introduced by oxida-tion.3 These polymer-SWNT materials offered new opportunities for the application of SWNTs in many fields such as optoelectronics4 and sensors.5 In this paper, we report our strategy of covalent polymer functionalization of the side wall of SWNTs. We find
