Abstract

A great deal has been learned about the excited states and photophysical properties of organometallic complexes from their emission data in recent years [1], In particular, complexes which emit in room-temperature solution yield valuable deactivation rate data under normally efficient photochemical conditions. On-going research in our laboratory has been concerned with the emission characteristics of metal carbonyl complexes in fluid solution; several of these systems are now known to exhibit room-temperature luminescence from low-lying metal to ligand charge- transfer (MLCT) excited states [2–4]. Recently, dual MLCT emission bands have been observed from M(CO)4(α-diimine) (M = Cr, Mo, W) complexes at room temperature [5,6]. This article reports absorption, emission and excitation data recorded from (η5-C5H5)Re(CO)2L (L = a substituted pyridine) complexes; the results indicate unusual multiple luminescence features in room-temperature solution. Emission results obtained from (η5-C5H5)Re(CO)2L (L = ammonia, piperidine) are also reported.
