New Ruthenium(II) Polypyridyl Complexes: Synthesis, characterization and perspectives

Ruthenium(II) polypyridyl complexes have attracted significant attention due to their remarkable photochemical and photophysical properties, making them promising candidates for applications in photodynamic therapy (PDT) and photoactivated chemotherapy (PACT)[1]. In this work, new Ru(II) complexes with the general formula [Ru(terpy)(N’N”)(THIQ)]2PF₆, where N’N” = bipyridine or phenanthroline derivatives and THIQ = 5,6,7,8-tetrahydroisoquinoline were investigated. Initially, the complexes were characterized by NMR using 1D and 2D techniques and X-Ray diffraction analysis, revealing that the ligands are coordinated in molecular framework.
