通过一种新型的四羧基功能化的1，2-乙二氨基-N，N′-bis(3-tertiarybutyl-5-((3，5-carboxybenzyl)oxy)salicylidene)(H6L)席夫碱配体的反应，合成了两个杂三金属有机骨架[(CH3)2NH2][Cd_2Na(Fe-L)_2(H_2O)_6]·4DMF·4H_2O(1)和[锌钠(Fe-L)(H_2O)]·2DMF·2H_2O(2)。在1和2中，L6−阴离子的内部[N2O2]口袋被Fe(III)离子包埋，而外部羧基被Zn(II)/Cd(II)和Na(I)离子连接。这两个框架都展示了引人入胜的3D框架。系统地研究了1和2在可见光下对4-氯苯酚(4-CP)和2，4-二氯苯酚(2，4-DCP)的光降解性能。还研究了它们的磁行为。
Two heterotrimetallic organic frameworks [(CH3)2NH2][Cd2Na(Fe-L)2(H2O)6]·4DMF·4H2O (1) and [ZnNa(Fe-L)(H2O)]·2DMF·2H2O (2), have been synthesized via the reaction of a novel tetracarboxyl-functionalized 1,2-ethanediamino-N,N′-bis(3-tertiarybutyl-5-((3,5-carboxybenzyl)oxy)salicylidene) (H6L) Schiff base ligand. In 1 and 2, the internal [N2O2] pockets of L6− anions are embedded by Fe(III) ions, while the external carboxylate groups are ligated by Zn(II)/Cd(II) and Na(I) ions. Both frameworks display fascinating 3D frameworks. The photodegradation properties of 1 and 2 towards 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) under visible light have been systematically investigated. Their magnetic behaviors have also been studied.
