Sub-gap optical absorption is measured under forward drive conditions in electroluminescent devices fabricated from thin films of poly (pphenylenevinylene) sandwiched between electrodes of indium/tin oxide and calcium. Quantitative concentrations of excitations are obtained. Absorption seen at 1.37
With the aid of in-situ absorption spectroscopy we performed a comparative study of the precursor route poly(pphenylene-vinylene) homopolymer and an acetoxy substituted copolymer derivative as a function of conversion temperature. It is shown that assuming a trans-cisoid conformation both polymers c
