Combining Single Wall Carbon Nanotubes and Photoactive Polymers for Photoconversion

摘要

A combination of van der Waals and electrostatic interactions was used to integrate SWNT and a suitably functionalized polythiophene into nanostructured ITO electrodes.In the resulting electron donor/ acceptor nanocomposites,polythiophene represents the light-harvesting chromophore that readily donates an excited-state electron to the ground-state electron-accepting SWNT.Upon illumination,monochromatic incident photoconversion efficiencies between 1.2 and 9.3% were determined for single and eight-sandwiched layers,respectively.
