A new class of room temperature luminescent organometallic complexes: luminescence and photophysical properties of permethylscandocene chloride in fluid solution

The search for organometallic complexes that emit in fluid solution at room temperature has been intensely pursued for the past 35 years because of the importance of an understanding of excited-state properties to the areas of solar energy conversion and photoassisted catalysis. Data are presented here on the photophysics of the d{sup 0} first row transition metal complex Cp*{sub 2}ScCl (Cp* = pentamethylcyclopentadienyl). To the best of their knowledge, this represents a new class of organometallic transition-metal complexes having no aromatic amine ligands that luminesce at room temperature in fluid solution.
