Dynamic cis/trans isomerisation in a porphyrin–fullerene conjugate

Abstract

A porphyrin with two fullerene substituents is prepared by condensation of a C₆₀ aldehyde derivative and dipyrrol-2-yl methane and by reaction of a preconstructed porphyrin with C₆₀ itself; it is obtained as a mixture of two conformers in slow equilibrium, as shown by a variable temperature NMR study.
