Metal-organic framework-177 (MOF-177) is one of the most porous materials whose structure is composed of octahedral Zn4O(-COO)6 and triangular 1,3,5-benzenetribenzoate (BTB) units to make a three-dimensional extended network based on the qom topology. This topology violates a long-standing thesis where highly symmetric building units are expected to yield highly symmetric networks. In the case of octahedron and triangle combinations, MOFs based on pyrite (pyr) and rutile (rtl) nets were expected instead of qom. In this study, we have made 24 MOF-177 structures with different functional groups on the triangular BTB linker, having one or more functionalities. We find that the position of the functional groups on the BTB unit allows the selection for a specific net (qom, pyr, and rtl), and that mixing of functionalities (-H, -NH2, and -C4H4) is an important strategy for the incorporation of a specific functionality (-NO2) into MOF-177 where otherwise incorporation of such functionality would be difficult. Such mixing of functionalities to make multivariate MOF-177 structures leads to enhancement of hydrogen uptake by 25%.

多元金属-有机框架中的功能介绍、拓扑选择和气体吸附增强-177
Metal-organic framework-177 (MOF-177) 是多孔材料之一,其结构由八面体 Zn4O(-COO)6 和三角形 1,3,5-苯三苯甲酸酯 (BTB) 单元组成,形成三维扩展基于qom拓扑的网络。这种拓扑结构违反了一个长期存在的论点,即高度对称的建筑单元有望产生高度对称的网络。在八面体和三角形组合的情况下,预计基于黄铁矿 (pyr) 和金红石 (rtl) 网的 MOF 代替 qom。在这项研究中,我们在三角形 BTB 接头上制作了 24 个具有不同官能团的 MOF-177 结构,具有一种或多种功能。我们发现 BTB 单元上官能团的位置允许选择特定的网络(qom、pyr 和 rtl),以及官能团(-H、-NH2、和 -C4H4) 是将特定功能 (-NO2) 结合到 MOF-177 中的重要策略,否则很难结合这种功能。这种混合功能以制造多元 MOF-177 结构导致氢吸收增加 25%。
