Noncovalent Functionalization of Single-Walled Carbon Nanotube by Porphyrin: Dispersion of Carbon Nanotubes in Water and Formation of Self-Assembly Donor-Acceptor Nanoensemble

摘要

A water-soluble nanoensemble of porphyrin and single-walled carbon nanotubes (SWNTs) was fabricated via electrostatic attraction. The formation of this supramolecular complex was monitored by UV-vis spectra and fluorescence spectra. The donor-acceptor properties of this nanoensemble were characterized by I-V performance of relative photovoltaic device fabricated by layer-by-layer (LBL) technique.
