Abstract

A microporous metal-organic framework 1 Zn 2(CNC) 2(DPT).G [CNC = 4-Carboxycinnamic; DPT = 3,6-Di-4-pyridyl-1,2,4,5-tetrazine; G = guest molecules] was synthesized and structurally characterized by a triply interpenetrated primitive cubic net with 1D pores of about 3.7 A. 1 is highly robust enforced by triple framework interpenetration through weak van der Waals interactions, thus the activated 1b takes up 1.28 wt % hydrogen gas and exhibits high hydrogen storage density of 95.2% at 1 atm and 77 K.

摘要

一种微孔金属有机骨架1 Zn₂(CNC)₂(DPT).G [CNC = 4 - 羧基肉桂酸；DPT = 3,6 - 二 - 4 - 吡啶基 - 1,2,4,5 - 四嗪；G = 客体分子] 被合成出来，并通过具有约3.7 Å一维孔道的三重互穿原始立方网络进行了结构表征。1通过弱范德华相互作用的三重骨架互穿而具有高度稳定性，因此活化后的1b在1个大气压和77 K下可吸收1.28 wt%的氢气，并且具有95.2%的高储氢密度。
