Abstract:
We report the "light switch" effect of [Ru(bpy)2(dppz)](2+) (where bpy = 2,2'-bipyridine and dppz = dipyrido[3,2-a:2',3'-c] phenazine, Ru-dppz) in the presence of anionic conjugated polyelectrolyte dendrimers (CPDs). The metal-to-ligand charge-transfer luminescence from Ru-dppz is efficient in the presence of CPD because the complex is shielded from water by binding to the hydrophobic dendrimer core.
