A Ru(II) complex (Ru) containing as ligands a tridentate 4’-p-tolyl-2,2’:6’,2 "-terpyridine (ttpy) and a tridentate 2,6-bis(4’-phenyl-2’-quinolyl)pyridine (bpqpy) has been covalently linked to a porphyrin module (PH2) to obtain a PH2-Ru dyad. The corresponding PZn-Ru dyad has then been obtained by metalation of the Gee base porphyrin with Zn(II) acetate. The photoinduced processes which occur on excitation of the PH2-Ru and PZn-Ru dyads, as well as of the PH2 and PZn porphyrin units and the [Ru(ttpy)(bpqpy)](2+) model compound Ru, have been investigated in butyronitrile rigid matrix at 77 K and fluid solution at 295 K. In both dyads at low temperature, the lowest singlet excited state of the porphyrin moiety (S-1) is quenched by energy transfer to give the triplet metal-to-ligand charge-transfer excited state of the Ru complex ((MLCT)-M-3) which, in its turn, is quenched by energy transfer to yield the triplet excited state of the porphyrin moiety (T-1).
