Pyridine-based ionic conjugated polymers have been used as material candidates for the fabrication of ultrathin amphiphilic films, cationic polyacetylene-silica nanohybrids, hybrid polymer gels, nanocrystalline CdS polymer sensitizer, SERS (surface-enhanced Raman spectroscopy) active pi-conjugated polymer-Ag nanocomposites, and unipolar write-once-read-many-times (WORM) memory devices. A new ionic polyacetylene with 4-nitrobenzenesulfonyl substituents was synthesized via the non-catalyst polymerization of 2-ethynylpyridine using 4-nitrobenzenesulfonyl chloride. The polymer structure was characterized by such instrumental methods as IR, NMR, and UV-visible spectroscopies to have the conjugated backbone system with the designed N-(4-nitrobenzenesulfonyl)pyridinium chloride. The photoluminescence peak was observed at 584 nm corresponding to a photon energy of 2.12 eV. |
