Intense near-infrared electrochemiluminescence facilitated by energy transfer in bimetallic Ir-Ru metallopolymers

Laena D'Alton et al.

Summary: A facile synthesis method of a bimetallic polymer with multiple emissive centers was demonstrated by modifying a partially photolyzed [Ru(bpy)(2)PVP10](2+) with an iridium precursor. The tunable emission color from near-infrared to green by adjusting the ratio of iridium to ruthenium centers was achieved. Transfer of energy between the iridium center and ruthenium centers was observed both in solution-phase and when immobilized as a thin layer, enhancing the electrochemiluminescence properties of the bimetallic polymer.
