摘　　要：以1,4-二(氯乙酰基)哌嗪(A)和N-烷基咪唑(B)为原料合成了哌嗪联接咪唑阳离子表面活性剂(I_(10),I_(12),I_(14),I_(16))。通过单因素实验,考察了N-烷基咪唑(B)和1,4-二(氯乙酰基)哌嗪(A)投料物质的量比、反应温度及反应时间对目标产物收率的影响。利用傅里叶红外光谱(FT-IR)和核磁共振氢谱(^(1)H-NMR)对目标产物结构进行表征。对产物熔点进行测试,结果表明,I_(16)化合物具有液晶态,在光电材料领域具有较好的应用价值。Imidazole cationic surfactants(I_(10),I_(12),I_(14),I_(16))of piperazine as linker were synthesized by using 1,4-bi-(chloracetyl)piperazine(A),N-alkyl imidazole(B)as raw materials.The influences of molar ratio of N-alkyl imidazole(B)and 1,4-bi-(chloracetyl)piperazine(A),reaction temperature and reaction time on the yield of target products were investigated via single factor experiment.The structure of the target products was confirmed by FT-IR and^(1)H-NMR.The melting point of the products were determined.The results show that the I_(16)compound has a liquid crystal state.It has good application value in the field of photoelectric materials.
