Abstract:
The luminescent DNA probe [Ru(phen)2dppz]2+, ruthenium (bis-1,10-phenanthroline di-pyrido-[3,2-a:2′,3′-c]phenazine), was the first tris-bidentate ruthenium complex to be shown unequivocally to intercalate DNA, which it achieves via insertion of the extended dipyridophenazine (dppz) ligand. The complex is non-luminescent in aqueous solution but emits strongly in organic solvents, micelles and DNA, with a quantum yield that depends on polarity, H-bonding, and protic ability of the medium. Studies of complexes with methylated dppz derivatives in a range of solvents have shown that a number of solvent factors influence the luminescent switching behaviour, the most intriguing of which is the implication of hydrogen bond formation between the dppz ligand and solvent molecules.
