Abstract
Diastereoisomers of a heteroleptic ruthenium complex, [Ru(bpy)(2)L](2+) (bp y = 2, 2'-bipyridine, L = 5-(4-nitrophenyl)-1-phenyl-3-(2-pyridyl)-2-pyrazo line) have been isolated. Two isomers have quite similar redox potentials a nd show MLCT absorptions in the region of 400 to 500 nm with similar absorp tion maxima at room temperature. By contrast, quite different emission maxi ma and lifetimes are observed at 77 K.
