Abstract

A polymer switch was explored utilizing the redox reaction of iodide ions with highly fluorescent s -triazine (ST)-bridged p -phenylene vinylene (PPV) polymers. The fluorescent polymers were synthesized through the Wittig polycondensation to yield ST-bridged PPV polymers. Utilizing different quenching properties of the polymer with iodine derivatives, the fluorescence of the polymers was modulated electrochemically in a two-electrode device consisting of the fluorescent polymer-doped gel layer containing an iodide and iodine couple and a solid polymer electrolyte layer. The cell showed reversible multistate fluorescence switching in the working potential range of +2 V.
