摘要：

Stable porphyrin/single-walled nanotube (SWNT) composites were synthesized by condensation of tetraformylporphyrins and diaminopyrenes on SWNTs. The degree of interaction between SWNTs and porphyrin was evaluated by UV-vis and fluorescence spectra, and chemical removal of porphyrin from SWNTs. In the composites, the Soret and Q-bands of porphyrin moieties were significantly broadened and their fluorescence was almost quenched. Apparent extinction coefficients at the Soret bands of the composites were decreased to ca. 20%.
