Photoinduced ligand dissociation follows reverse energy gap law: nitrile photodissociation from low energy 3MLCT excited states.

Lauren M Loftus1, Jeffrey J Rack2, Claudia Turro1.   

Abstract

A series of Ru(ii)-terpyridine complexes containing electron-donating bidentate ligands are able to effectively photodissociate nitrile ligands using red light. A spectroscopic investigation of these complexes reveal that they follow anti-energy gap law behavior, providing further evidence that population of 3LF excited states is not necessary for photoinduced nitrile dissociation.
