摘要: 在四氮杂大环的氮原子上引入具有电离功能团的取代基,可改善其配位性能,有可能应用于离子的识别和分离.Alberts和Stetter等以氯乙酸与四氮杂大环在受控制的弱碱性水溶液中进行均相反应来制备N-乙酸取代四氮杂大环.缺点是调节溶液的碱度困难,且氯乙酸在碱性水溶液中易水解生成轻基乙酸而影响反应产率.

Abstract: A novel 14 membered N-acetic acid substituted tetraazamacrocyclic ligand, 5,12-diphenyl-7,14-dimethyl-l,4,8,11-tetraazacyclotetradecane-N-acetic acid (HL ) has been synthesized in dry methanol by the interaction of 5,12-diphenyl-7,14-dimethyl-1,4,8,11-tetraazacyclotetradecane with bromoacetic acid. Its Cu (Ⅱ) and Ni(Ⅱ) complexes have also been prepared. The ligand and the complexes have been characterized by elemental analysis.IR,1H NMR,MS,UV-Vis spectra and conductivity measurements.

Key words: tetraazacyclotetradecane-N-acetic acid, complex, synthesis, characterization
