摘要：

The luminescence of Ru(bipy)2dppz2+ (dppz is dipyrido[3,2-a:2',3'-c]phenazine) was previously shown to be totally quenched in water solutions, whereas the complex is luminescent in organic solvents. In sodium dodecyl sulfate aqueous solutions, this complex luminesces strongly above the critical micellar concentration. This latter result correlates well with the observations in alcoholic solvents with long alkyl chains. It is interpreted in terms of the shielding of the dipyridophenazine ligand (at which quenching of the emission occurs) from the water molecules by the micellar core.
