Synthesis and Electro-Optical Properties of an Ionic Polyacetylene with N-glycidylpyridinium Tosylate

Abstract

An ionic conjugated polymer with a reactive glycidyl functionalities, poly(2-ethynyl-N-glycidylpyridinium tosylate), was synthesized by the activated polymerization of 2-ethynylpyridine with glycidyl tosylate. The instrumental analyses on the polymer structure revealed that the present polymer have a conjugated polymer backbone system with the designed substituents. The photoluminescence peak is located at 710 nm corresponding to the photon energy of 1.75 eV. The cyclic voltammogram of this conjugated polyelectrolyte revealed that it show the well-defined and stable redox process.
