摘要：

Solid-state electronic (UV-Vis) and vibrational (IR) spectra of several fullerene-porphyrin conjugates were recorded in KBr in the spectral range between 400 and 50,000 cm(-1). It was observed that significant redistribution of the charges occurs in both fullerene and porphyrin moieties upon covalent linkage. This effect is mainly observed as shifts of both electronic and vibrational bands in comparison with the respective free porphyrin and fullerene features. Variable temperature IR measurements were also performed. (C) 2004 Elsevier B.V. All rights reserved.
