Abstract
Counter anions having oxidative properties alter the performance of solution processed multilayer polymer light emitting diodes (PLEDs) that use cationic conjugated polyelectrolytes (CPEs) as electron injection layers (EILs). In some versions, PLEDs with poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene) (MEH-PPV) emissive layers and cationic CPE EILs are altered with halide counter anions to exhibit a systematic increase in device performance. Exemplary oxidative counter anions are halide counter anions with F>Cl>Br>Iin terms of device performance.
