Resumo

Here, we investigate the effects introduced in the spectroscopic properties and singlet oxygen generation efficiency of zinc tetra(4-pyridyl) porphyrin (ZnTPyP) when the molecule undergoes outlying decoration with the [RuCl2(PPh3)2(CO)(DMF)] and [RuCl2(dppb)(CO)(DMF)] ruthenium complexes. Our results show that these metallic compounds can significantly affect the electronic and vibronic B- and Q-bands; the excited-state deactivation processes; and the singlet oxygen generation quantum yield of the porphyrin, being their influence affected by the ligands present in the ruthenium complexes.
