AbstractA new electroluminescent copolymer [poly(1,5-di(3,5-dimethyloxystyrylene)naphthalene-block-tri(ethylene oxide)) (DSN-TEO)], containing alternating rigid, conjugated light-emitting units and flexible tri(ethylene oxide) ionic conductive units, was synthesized via the Wittig reaction. The polymer has fairly good solubility in chloroform, tetrahydrofuran, toluene, etc, and excellent film-forming ability. The decomposition temperature and the glass transition temperature were 409degreesC and 42.2degreesC, respectively. A light-emitting diode (LED) device with configuration ITO/PEDOT-PSS/DSN-TEO/Ca(Al) and light-emitting electrochemical cell (LEC) device with ITO/DSN-TEO+PEO (LiTf)/Al were prepared, and the photoluminescence and electroluminescence (EL) properties were investigated. Efficient blue-green light emission (EL maximum emissive wavelength at 508 nm) was found with onset voltage at 6V. The maximum light efficiency was 0.107 cd A(-1) at 20V for LED, and the onset voltage 2.5V and the maximum light efficiency was 4.2cd A(-1) at 2.8V for LEC, respectively. The response time of the LEC was less than 5s. The EL efficiency of LEC device was improved by 44 as compared with the relative LED device. (C) 2003 Society of Chemical Industry.
