Poly(2,5‐dimethoxy‐1,4‐phenylene vinylene) (PDMoPV) prepared via the chlorine precursor route (CPR) exhibits absorption at a shorter wavelength than that obtained by the Wessling method. The polymer fluoresces at a maximum of 505 nm as compared to 540 nm by Wessling method. Both the fabricated ITO–PDMoPV (via CPR)–Al and ITO/PDMoPV (via Wessling method)–Al devices emit green‐blue light and the turn‐on voltages are relatively low at 7 and 4 V, respectively. Significantly, the device fabricated using PDMoPV via CPR has a higher output than that via the Wessling method. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 73: 2177–2181, 1999
