Polarized electroluminescence from an oriented poly (3-alkylthiophene) langmuir–blodgett structure

Abstract

Polarized electroluminescence (EL) from an oriented poly(3-alkylthiophene) structure is reported, which is a first step towards the fabrication of an organic light-emitting diode (LED) that emits polarized light. A multilayer structure is described that includes a Langmuir-Blodgett film of poly(3-decylmethoxythiophene), PDMT, in which the polyenic backbones are oriented along the dipping direction. The optical properties–absorption, EL, photoluminescence–and the IV curve for an ITO/PDMT/Al device are presented.
