Dual Emission from 3MLCT and 3ILCT Excited States in a New Ru(II) Diimine Complex

Dual Emission from 3MLCT and 3ILCT Excited States in a New Ru(II) Diimine Complex

The unique behavior of a new Ru(II) diimine complex, Ru(bpy)2(L)2+ (where L is 4-methyl-4‘-[p-(dimethyl- amino)-α-styryl]-2,2‘-bipyridine, bpy is 2,2‘-bipyridine), was studied in detail. Due to the strong electron donating property of the amino group, an ILCT (intraligand charge transfer) state is i...

description The unique behavior of a new Ru(II) diimine complex, Ru(bpy)2(L)2+ (where L is 4-methyl-4‘-[p-(dimethyl- amino)-α-styryl]-2,2‘-bipyridine, bpy is 2,2‘-bipyridine), was studied in detail. Due to the strong electron donating property of the amino group, an ILCT (intraligand charge transfer) state is involved either in the absorption spectra or in the time-resolved emission spectra. Dual emission based on 3MLCT and 3ILCT states was observed at room temperature for the first time via a time-resolved technique in Ru(II) diimine complexes.
