通过N3O2大环化合物1, 12, 15-三氮杂-3,4:9, 10-二苯-5,8-二氧杂环十七烷(以下简称为L)与乙酸酐、苯甲酰氯、邻苯二甲酸酐在吡啶介质中反应, 合成了N,N′,N″-三乙酰(L1)、 N, N′, N″-三(2-羧基)苯甲酰(L2)、 N, N′, N″-三苯甲酰(L3)N3O2大环配体, 并制备了L1的Sm, Eu, Tb, Dy稀土硝酸盐的配合物. 通过元素分析、摩尔电导、热分析、红外的测定对配合物进行了表征. 结果表明, L1母体环上的醚氧、酰胺氮均没有参与对稀土离子的配位, 并推测了配合物的可能组成. 室温下研究了配合物的固体荧光光谱, 固态时的配合物(除Sm3+配合物外)均有较强荧光, 其中Tb3+配合物的荧光强度最高, 表明配体三重态的能量与Tb3+的振动能级更为匹配. 在Eu3+的配合物中, 强度比η(5D0→7F2/5D0→7F1)=3.7, 表明Eu3+处于一非对称配位环境中.
