Abstract
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.
