Abstract

A novel supramolecular dyad (Zn-ttbpp–pyridine–C₅₉N)—with a quasi-linear geometry—involving a heterofullerene acceptor and a zinc tetrakis(p-tert-butylphenyl)porphyrin (Zn-ttbpp) donor was assembled via axial coordination. Depending on the solvent either photoinduced singlet–singlet energy transfer or electron transfer was observed. The latter process takes place in o-dichlorobenzene as solvent and leads to the corresponding charge-separated state, that is, the π-radical anion of C₅₉N and the π-radical cation of Zn-ttbpp.
