Abstract

We present photoluminescence (PL) and electroluminescence (EL) studies of multilayer heterostructures containing alternate layers of conjugated copolymers and non-conjugated polymers (spacers). The self-assembled films are prepared either by electrostatic interactions between oppositely charged polyelectrolytes or using hydrogen bonding between molecules. We can tune both the PL and EL emission from blue to red region by: (a) using different copolymers with different emission properties; (b) controlling the thickness of the spacer layers in the assemblies; and to some degree (c) using different pH values of the polyelectrolyte solution.
