from two and/or four porphyrin units. These molecules form stable complexes with fullerenes in a toluene solution and exhibit selectivity towards C70. The observed fullerene–porphyrin contacts suggest cooperative behaviour of closely separated porphyrin units attracting C60 or C70. Measurements show efficient quenching of porphyrin fluorescence emission.
