Quantum yields for loss of a single CO ligand in alkane solutions were determined for the (η3-allyl)Ru(CO)3X complexes, where X = Cl, Br, I, and various (diene)Ru(CO)3 complexes. Excited states were assigned as MLCT or LF on the basis of solvatochromism and DFT studies. The solution phase photochemistry was proposed to occur by excitation of an MLCT transition. Very little luminescence was observed for the compounds, demonstrating that radiative decay of the excited states was not competitive with their photochemical reactions. The photochemistry will be discussed in the context of precursor design for photochemical deposition techniques.
