Preparation of graphene platelet-Ru(phen)32+ assemblies and their application in electrochemiluminescence detection

Graphene platelet (GP)-Ru(phen) (3) (2+) assembles have been prepared through self-assembly of poly sodium styrenesulfonate (PSS) functionalized GPs and Ru(phen) (3) (2+) driven by electrostatic attraction interactions in aqueous solution. The resultant assembled GP-Ru(phen) (3) (2+) hybrid structure modified electrode exhibits excellent electrochemiluminescence (ECL) behaviors because of the ECL active species Ru(phen) (3) (2+) contained therein.
