Abstract
Photoluminescence spectra in solution and thin films were measured for a polyester with isolated dimethoxyquaterthiophene units in the main chain. Light-emitting diodes were fabricated using indium-tin oxide (I TO)/polyester/Al sandwiches. N,N-dilauryl naphthalene tetracarboxylic acid diimide, added as an electron transport agent, gave improved perf ormance. The emitted light was orange and had lambda(max) 595 nm. Devi ces constructed with a 240 nm thick polymer film had an emission thres hold of about 15 V and 4 mA cm(-2).
