A p-Phenylene Vinylene Polymer Bridged by a Triazine for Electro-Fluorescence Switching.

A highly fluorescent s-triazine (ST) bridged p-phenylene vinylene (PPV) polymer was synthesized by the Wittig polycondensation reaction of 4, 6-bis (4-formylphenoxy)-2-diphenylamino-s-triazine and 2, 5-bis (triphenylphosphonionmethyl)-1, 4-bis (trimethylsilyl) benzene dibromide, to afford ST bridged PPV polymer (DTTPV). The fluorescence of the polymer was dramatically changed by the application of the external potential from - 2 V to 2 V in a two electrode cell containing a solid polymer electrolyte layer. The fluorescence switching was reversible with a switching time of 4s. [ABSTRACT FROM AUTHOR]
