Abstract

We have investigated a new light emitting material, Ru(bpy)3 2+ polyester for fabricating electrochemically based solid state light emitting devices using the layer-by-layer sequential adsorption processing technique. By controlling the deposition conditions such as the pH of the Ru(bpy)32+ polyester and poly(acrylic acid) (PAA) solutions, we systematically altered the layer thickness and bilayer composition to obtain multilayers that contain different amounts of Ru(bpy)32+ polyester (from 46% to 70%). Differences in the Ru(bpy)32+ polyester composition, in turn, influence the device performance dramatically.
