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

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 I – V curve for an ITO/PDMT/Al device are presented.
