通过合理设计11种同构两性离子金属有机骨架（ZW-MOFs），系统地研究了荷电极化孔隙的等网格扩张和功能化。通过溶剂热反应，由Co和Ni的四氟硼酸盐与由两性离子吡啶衍生物和传统的官能化的双配位羧酸辅助配体组成的二元配体体系制备了该扩展系列的一般结构组成{[M3 F（L1）3（L2）1.5]·guests}n（HL 1·Cl = 1-（4-羧基苯基）-4，4 ′-联吡啶鎓氯化物，Hcpb·Cl;或1-（4-羧基苯基-3-羟基苯基）-4，4 ′-联吡啶氯化物，Hchpb·Cl; H2 L2 =苯-1，4-二甲酸，H2 bdc; 2-氨基苯-1，4-二甲酸，H2 abdc; 2，5-二羟基-1，4-苯二甲酸，H2 dhbdc;联苯-4，4 ′-二甲酸，H2 bpdc;或芪-4，4 ′-二甲酸，H2sdc）。单晶结构分析表明，立方晶体对称性（I-43 m，a = 31-36 A），具有显著的体积分数的3D孔隙系统。
The isoreticular expansion and functionalization of charged-polarized porosity has been systematically explored by the rational design of 11 isostructural zwitterionic metal–organic frameworks (ZW-MOFs). This extended series of general structural composition {[M3F(L1)3(L2)1.5]·guests}n was prepared by employing the solvothermal reaction of Co and Ni tetrafluoroborates with a binary ligand system composed of zwitterionic pyridinium derivatives and traditional functionalized ditopic carboxylate auxiliary ligands (HL1·Cl = 1-(4-carboxyphenyl)-4,4′-bipyridinium chloride, Hcpb·Cl; or 1-(4-carboxyphenyl-3-hydroxyphenyl)-4,4′-bipyridinium chloride, Hchpb·Cl; and H2L2 = benzene-1,4-dicarboxylic acid, H2bdc; 2-aminobenzene-1,4-dicarboxylic acid, H2abdc; 2,5-dihydroxy-1,4-benzenedicarboxylic acid, H2dhbdc; biphenyl-4,4′-dicarboxylic acid, H2bpdc; or stilbene-4,4′-dicarboxylic acid, H2sdc). Single-crystal structure analyses revealed cubic crystal symmetry (I-43m, a = 31–36 A) with a 3D pore system of significant voi...
