Abstract

The patterning of conjugated polymers for multicolored electroluminescence applications is a current topic of research in polymer device technology. Several techniques including direct writing approaches such as ink-jet printing have been proposed to solve this challenge. We present an approach to tuning the (electro)luminescence color of a film consisting of a blend of conjugated polymers after its deposition by means of UV-irradiation in the presence of an active agent. This promises to be an alternative, highly parallel approach towards multicolored electroluminescence.
