Abstract A new ionic polyacetylene having perfluorinated benzyl substituent, poly(2-ethynyl-N-heptafluorobenzylpyridinium iodide), was synthesized via the direct polymerization of the quaterinazed acetylenic pyridinium monomers. The polymerization proceeded homogeneously without any additional initiator or catalyst to give a moderate yield of polymer. The results of instrumental analyses on the molecular structure of polymer revealed that the polymer have polyacetylene backbone system with N-heptafluorobenzylicpyridinium iodide as substituent. The photoluminescence (PL) spectra of polymer exhibited that the PL peak is located at 550 nm, corresponding to a photon energy of 2.26 eV. The irreversible electrochemical behaviors of polymer between the doped and undoped peaks were observed in the cyclic voltammograms of polymer. The initial oxidation and reduction of poly(EHFBPI) occurred at 0.53 V and -0.75 V (vs Ag/AgNO3). HOMO level of poly(EHFBPI) was 5.27 eV.

使用七氟苄基碘通过 2-乙炔基吡啶非催化剂聚合制备聚乙炔聚电解质

摘要 通过季铵化乙炔吡啶单体的直接聚合，合成了一种具有全氟苄基取代基的新型离子聚乙炔，聚（2-乙炔基-N-七氟苄基碘化吡啶）。在没有任何额外的引发剂或催化剂的情况下，聚合均匀地进行以得到中等收率的聚合物。对聚合物分子结构的仪器分析结果表明，该聚合物具有聚乙炔骨架体系，以N-七氟苄基碘化吡啶鎓为取代基。聚合物的光致发光 (PL) 光谱表明 PL 峰位于 550 nm，对应于 2.26 eV 的光子能量。在聚合物的循环伏安图中观察到聚合物在掺杂和未掺杂峰之间的不可逆电化学行为。聚 (EHFBPI) 的初始氧化和还原发生在 0.53 V 和 -0.75 V（相对于 Ag/AgNO3）。聚 (EHFBPI) 的 HOMO 能级为 5.27 eV。
