The polymerization of dimethylphenylpropargylammonium bromide (DMPPAB) was performed by various transition metal catalysts to give the resulting polymer in high yield. The polymer structure was characterized by various instrumental methods to have a conjugated polymer backbone system having the designed substituent. This polymer was mostly soluble in organic solvents. The electrochemical properties of poly(DMPPAB) were measured and discussed. 我们合成并表征了一个含有季铵盐的单取代离子聚乙炔。用不同的过渡金属催化剂，聚合二甲基苯基炔丙基溴化铵(DMPPAB) 得到的聚合物的产率都很高。通过不同的仪器对得到的聚合物的结构进行了表征，表明聚合物有一个共轭的骨架体系和设计的取代基。这个聚合物可以溶解在有机溶剂中， 讨论并测定了poly(DMPPAB) 的电化学性质。 introduction Considerable progress has been made in the synthesis and applications of oligomers and polymers having a π-conjugated backbone [1–7]. These conjugated organic materials are expected to show unique properties such as electrical conductivity, paramagnetism, migration and transfer of energy, color, and chemical reactivity and complex formation ability [1,8]. Because of these properties, polyacetylene and its homologues have been promising materials for photovoltaics, displays, lasers, nonlinear optical materials, membranes for gas separation and for liquid-mixture separation and chemical sensors [4–7,9–13]. 有π-共轭骨架的聚合物和低聚物的合成和应用已经取得了相当大的进展[1–7] 。这些共轭的有机材料被期望表现出独一无二的性质，如：电导性、顺磁性、能量迁移、有色性、化学活性和形成混合物的能力[1,8] 。因为这些性质，聚乙炔和它的同系物有望成为光伏打材料、显示器、激光、非线性光学材料、气体分离膜、混合物液体分离膜和化学传感器[4–7,9–13] 。 Polyelectrolytes are charged macromolecules containing a large number of ionizable or ionic groups. The natural polyelectrolytes have been used in water-cleaning processes for centuries. The very building blocks of life, the nucleic acids and proteins, are polyelectrolytes.
