Photoinduced electron transfer in a non-covalently linked donor–acceptor system: a bis-porphyrinic host and a naphthalene diimide guest

Abstract

Complexation of the two pyridyl residues of a naphthalene imide guest by a V-shaped bis-porphyrinic host occurs with an association constant of the order of 108 M−1 and results in the quenching of the porphyrin luminescence with a rate of 1.2 × 1010 s−1, assigned to electron transfer.
