FLUORESCENCE QUANTUM YIELD IN PHENYLENEVINYLENE SYSTEMS

In this paper, we report the synthesis and optoelectronic characterization of three phenylene vinylene systems with electron- donor substituents (alcoxide type, -OR). The systems were obtained by Heck cross-coupling reaction, with yields over 95%, pure trans configuration conjugation, and high fluorescent quantum yields of blue-green color. The high stereoselectivity of the synthesis used is shown by obtaining fluorescence quantum yields higher than similar phenylene vinylene systems reported in literature, which makes these systems very attractive materials for the emerging polymer electronic technology.
