Abstract

Poly (2-ethynylpyridinium trifluoroacetate) (P2EPF) was synthesized by the spontaneous polymerization of 2-ethynylpyridine (2-EP) and trifluoroacetic acid (TFA). TFA, as a strong acid for sufficient activation of the acetylenic triple bond, was used in the spontaneous polymerization of 2-EP producing conjugated and ionic polyacetylenes. P2EPF was soluble in polar organic solvents due to inherent characteristics of ionic polymers. The chemical structure and composition of P2EPF were characterized by 1H-NMR, 13C-NMR, FT-IR, and UV-Vis spectrometer. The fluorescence spectra of P2EPF suggested that P2EPF were successfully synthesized as potential conducting materials.
