Good Vibrations Report on the DNA Quadruplex Binding of an Excited State Amplified Ruthenium Polypyridyl IR Probe

[Image: see text] The nitrile containing Ru(II)polypyridyl complex [Ru(phen)(2)(11,12-dCN-dppz)](2+) (1) is shown to act as a sensitive infrared probe of G-quadruplex (G4) structures. UV–visible absorption spectroscopy reveals enantiomer sensitive binding for the hybrid htel(K) and antiparallel htel...
