Highly Efficient Solid-State Electrochemically Generated Chemiluminescence from Ester-Substituted Trisbipyridineruthenium(II)-Based Polymers

Abstract

A polymerizable ester-substituted trisbipyridine complex of ruthenium(II) has been synthesized and the solid-state electrochemiluminescence (ECL) properties of its polymer evaluated. A collection of 12 “sandwich-type” solid-state cells were investigated each having a ∼0.3 μm thick film of the polymer sandwiched between a transparent indium/tin oxide (ITO) anode and a porous Au cathode. The ECL of these devices was evaluated in the solid state. Despite considerable variability in performance, the most efficient of these devices exhibited ECL quantum yields matching the efficiency of the best organic polymer based light-emitting devices.
