1. Evidence for a lowest energy 3MLCT excited state in [Fe(tpy)(CN)3]−.

Author

Abstract

Transient absorption data of [FeII(tpy)(CN)3]− reveals spectroscopic signatures indicative of 3MLCT with a ∼10 ps kinetic component. These data are supported by DFT and TD-DFT calculations, which show that excited state ordering is responsive to the number of cyanide ligands on the complex. [ABSTRACT FROM AUTHOR]

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.
