设计了新的不对称四羧酸配体2,2'-（6-氯-1,3,5-三嗪-2,4-二基）双（氮杂二基）二对苯二甲酸（H4L1）和六羧酸配体2,2',2 ''-（（1,3,5-三嗪-2,4,6-三基）（氮杂二基））三对苯二甲酸（H6L2），并将其用于与Cd2+离子的组装反应。合成了[Cd-2(L-1) (H2O)(2)]中心点2.5DMSO中心点2H(2)O(1)和（Me2NH2）(9)(h30)(2)[Cd2Cl3(L-2)(2)]中心点5H(2)O(2)并进行了结构表征。单晶x射线分析表明，化合物1具有基于3连接{Cd-2}节点和3连接间隔的二维中性（4,8）网。2是第一个以单原子Cl连接剂为支柱的双层mof，其结构由4连接的单金属节点和3连接的间隔片构成。所得到的（3,4）连接阴离子框架的拓扑结构可以描述为（6(3)）（6(6)）（Schlafli符号）。N-2的吸附等温线表现为典型的I型行为，BET表面积为599 m(2) g(-1)，微孔体积为0.2345 cm(3) g（-1）。发光分析表明，这两种化合物都表现出连接局域发光。此外，还对化合物的红外（IR）、热重分析（TGA）性能进行了研究。(C) 2015 Elsevier B.V.版权所有
New asymmetric tetra-carboxylates ligand, 2,2'-((6-chloro-1,3,5-triazine-2,4-diyl)bis(azanediyl)) diterephthalic acid (H4L1) and hexa-carboxylates ligand, 2,2',2 ''-((1,3,5-triazine-2,4,6-triyl)(azanediyl))-triterephthalic acid (H6L2), were designed and used for the assemble reactions with Cd2+ ions. [Cd-2(L-1) (H2O)(2)]center dot 2.5DMSO center dot 2H(2)O (1) and (Me2NH2)(9)(H3O)(2)[Cd2Cl3(L-2)(2)]center dot 5H(2)O (2) have been synthesized and structurally characterized. Single crystal X-ray analysis show that compound 1 bears a 2D neutral (4, 8)-net based on 3-connected {Cd-2} nodes and 3-connected spacers. 2 is the first bilayer MOFs pillared by monatomic Cl linker and its structure is built of 4-connected single metal nodes and 3-connected spacers. The topology of the resulted (3, 4)-connected anionic framework could be described as (6(3))(6(6)) (Schlafli symbol). N-2 sorption isotherm of 2 shows typical type I behavior with BET surface area of 599 m(2) g(-1) and a micropore volume of 0.2345 cm(3) g(-1). Luminescent analysis indicates both compounds exhibit linker-localized emission. Furthermore, infrared (IR), thermogravimetric analyses (TGA) properties of the compounds were also investigated.
