在NaOH存在下，N，N′，N″，N-四乙酸-1，4，7，10-四氮杂环十二烷、N，N′，N″，N-四乙酸-1，4，8，11-四氮杂环十四烷、N，N′，N″，N-四甲磷酸-1，4，7，10-四氮杂环十二烷和N，N′，N″，N-四甲磷酸-1，4，8，11-四氮杂环十四烷分别与LaCl3·7H2O或GdCl3·6H2O通过大环配体络合物直接合成法，得到八个络合物，产率为46．7％～90．7％。

In the presence of sodium hydroxide, eight lanthanide complexes with a polyaza macrocycle were synthesized by the reaction of 1, 4, 7, 10-tetraazacyclododecane-N, N′,N″, N-tetraacetic acid、 1, 4, 8, 11-tetraazacyclotetradecane-N, N′,N″ -N-tetraacetic acid、1, 4, 7, 10-tetraazacyclododecane -N, N′,N″ -N-tetramethylenephosphonate and 1, 4, 8, 11-tetraazacyclotetradecane -N, N′,N″ -N-tetramethylenephosphonate,separately, with LaCl3· 7H2O or GdCl3·6H2O. The yields of these macrocyclic ligandcomplexes were 46. 7%~90. 7%.
