Supramolecular porphyrin–fullerene viatwo-point binding strategy: Axial-coordination and cation–crown ether complexation

A highly stable porphyrin–fullerene conjugate with defined distance and orientation, was formed using a newly developed two-point binding strategy involving axial-coordination and cation–crown ether complexation; photochemical studies performed in benzonitrile revealed efficient charge separation and slow charge-recombination in the supramolecular complex.
