Abstract

We report photoluminescence property of poly(2-fluoro-1,4-phenylene vinylene) (PFPV) comparing with that of poly(1,4-phenylene vinylene) (PPV). They were investigated by using steady-state and time-resolved photoluminescence spectroscopy. PFPV showed higher PL quantum efficiency and longer PL lifetime than PPV, which was explained in terms of a trapping of excitons into shallow traps formed by donor-acceptor states between PPV and fluorine substituent. A model oligomer, 1,4-bis(2-fluorestyryl)2-fluorobenzene, was synthesized through Wittig reaction to understand the PL property of PFPV. Comparison of the results for the oligomer and the polymer provides a useful insight into the properties of the polymer, PFPV.
