Biological target selectivity and strong photogeneration of reactive oxygen species are highly sought properties for therapy. Here, two ruthenium metal complexes containing a ligand conferring DNA binding and another one enhancing singlet oxygen photoproduction were prepared. These compounds showed great photochemical activity along with DNA binding and photocleavage using visible light. These successful complexes have great potential in photodynamic therapy and cell biology studies.
