文摘

A straightforward synthesis of a fullerene derivative appended with a barbituric acid molecular recognition motif is described. The presence of two nonself-complementary hydrogen-bonding sites is shown to be conducive to the construction of supramolecular assemblies. In the presence of a melamine derivative possessing complementary hydrogen-bonding sites, enhanced efficiency toward photodimerization of the fullerene moiety is observed. This represents the first example of intermolecular photodimerization of a fullerene derivative in homogeneous solution, made possible by the formation of supramolecular assemblies in which the fullerenes are maintained in close proximity.
