摘要：Cobalt metal organic framework (MOF) materials CoL(1,4-chdc)center dot mH(2)O (1,4-chdc = 1,4-cyclohexanedicarboxylic acid, L1 = 1,2-di(4-pyridyl)ethylene, and m = 0 for 1Co; L2 = 1,4-bis(4-pyridy1)-2,3-diaza-1,3-butadiene and m = 2 for 2Co) were assembled in a MeOH-H2O solvent system. They crystallized in a monoclinic system with space group P2(1)/c, Z = 4, a = 9.479(4) angstrom, b = 13.704(6) angstrom, c = 14.455(6) angstrom, and beta = 99.424(6)degrees for 1Co, and a = 14.349(11) angstrom, b = 12.088(9) angstrom, c = 26.62(2) angstrom, and beta = 97.255(11)degrees for 2Co. It was shown that N-ligand can regulate and control the conjunctive orientation of carboxyl groups in these MOFs; thus, the MOFs exhibited structures that ranged from layers to micropores. Furthermore, the micro-nanoparticles of 1Co and 2Co were investigated for new potential applications of micro-nano MOFs. (C) 2015 Elsevier B.V. All rights reserved.
