The attachment of two polyethylene glycol tails (n = 7, MW = 350) to ruthenium tris(bipyridine) via ester links on the 4,4′-positions of one of the bipyridine ligands yields a highly viscous (eta ? 107 cP) molten salt (abbreviated [Ru(bpy)2(bpy(CO2MePEG350)2)](ClO4)2) that glasses at ca. – 5 C. At room temperature, the ionic conductivity of the melt is sufficiently high that application of 2.4 V across the fingers of a Pt interdigitated electrode array (IDA) coated with the melt leads to the electrolytic development of serial concentration gradient microstructures of Ru(III/II) and Ru(II/I) states. At the intersection of the two concentration gradients, in the interior of the coating, reaction between the Ru(III) and Ru(I) states leads to ECL emission with an efficiency of 0.2% photons/electron. Cooling a concentration gradient-containing film to -20 C under voltage bias, so as to preserve the gradient microstructure, yields a film that has an emission efficiency of 0.1%, a current and light emission response that rapidly changes with the applied voltage bias, and a diode- like current-voltage profile with a ca. 100 rectification ratio.
