title: Preparation of a [Ru(bpy)2(dppz)]2+-intercalated DNA cast film using a self-standing method and its luminescence tuning by Cu2+ ions and EDTA.
abstract: In this correspondence, we report on the first preparation of [Ru(bpy)(2)(dppz)](2+)-intercalated (bpy = 2,2'-bipyridine; dppz = dipyrido[3,2-a:2',3'-c]phenazine) DNA films on an indium-tin oxide surface via a solution-based self-standing strategy, carried out by the direct mixing of aqueous solutions of both anionic DNA and cationic metallointercalator at a molar ratio of 5:6. The luminescence of a [Ru(bpy)(2)(dppz)](2+)-intercalated DNA cast film is studied and found to show excellent tunable characteristics by Cu(2+) ions and ethylenediaminetetraacetic acid addition.
