利用锌-1，2，4-三氮唑层状结构和两种不同官能团(反式，反式-1，3-丁二烯-1，4-二羧酸，TTBDC和2，5-二羟基对苯二甲酸，DOBDC)的等长二元羧酸盐配体，我们在这里报道了两种柱层式锌-三氮唑二羧酸锌多孔膜。在PNa2 1空间群中，柔性的TTBDC导致了MOF1的结晶，而在P4/NCC空间群中，刚性的DOBDC生成了MOF2。两种柱状MOF不仅表现出显著的吸氢和吸CO2能力，而且具有较高的CO2对CH4的选择性。(C)2015爱思唯尔B.V.保留所有权利。
Take advantage of the readily accessible layered Zn-1,2,4-triazolate motif and two isometric dicarboxylate ligands with different functional groups (trans,trans-1,3-butadiene-1,4-dicarboxylic acid, TTBDC and 2,5-dihydroxyterephthalic acid, DOBDC), we report herein two porous Zn-triazolate-dicarboxylate pillar-layered MOFs. Flexible TTBDC led to the formation of MOF 1 crystallizing in Pna21 space group, but rigid DOBDC produced MOF 2 in P4/ncc space group. Both pillar-layered MOFs show not only remarkable H-2 and CO2 uptake capacity, but also high CO2 over CH4 selectivity. (C) 2015 Elsevier B.V. All rights reserved.
