摘要：
A femtochemistry study has been performed on two phytochlorin-[60]fullerene donor-acceptor dyads, in which the fullerene moiety is linked via a pyrrolidine bridge either to the position 3 or 7 of the phytochlorin ring. Both dyads form an emissive intramolecular exciplex in less than 1 ps, but only the former dyad relaxes to the ground state via a charge transfer (CT) state. (C) 2001 Elsevier Science B.V.
