Abstract

We report the characterisation of an insoluble MEHPPV (I-MEHPPV) prepared via a chloro precursor route. Optical absorption and emission spectra are discussed with reference to those of the common soluble variant. PL quantum efficiencies are also reported. Results obtained for single ITO/I-MEHPPV/Al and double layer ITO/I-MEHPPV/electron transport layer (ETL)/Al LED structures are discussed. Peak luminances of 800cd/m2 are found for the multilayer device and a peak EL external quantum efficiency of 0.11% (power conversion efficiency of 1.5×10-5 W/W) is obtained.
