✦ Synopsis

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.
