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.
