Convergent synthesis and photophysics of [60]fullerene/porphyrin-based rotaxanes

J Am Chem Soc. 2004 Mar 24;126(11):3388-9. doi: 10.1021/ja039698h.

Abstract

A series of Sauvage-type rotaxanes containing [60]fullerene and tetraarylporphyrin moieties has been synthesized by a convergent route. Photoinduced energy-transfer and electron-transfer reactions in these rotaxanes yield long-lived change-separated states, in agreement with the large distance between the fullerene and porphyrin chromophores.
