H4L5, respectively. Furthermore, their C2H2 adsorption properties were systematically investigated, revealing that their different C2H2 uptake capacities can be mainly related to their different pore sizes since they possess the same chemical compositions and gravimetric densities of open metal sites. In particular, of these five MOF compounds investigated, ZJNU-71 exhibits the highest gravimetric C2H2
在这项工作中,五个位置异构体配体由两个以不同方式连接到中心萘基核上的周边邻苯二甲酸酯部分组成,即5,5'-(萘基-1,3-二基萘基)二间苯二甲酸酯(H4L1),5,5'- (1,4-萘基萘基)二间苯二甲酸酯(H4L2),(5,5'-(1,5-萘基萘基)二间苯二甲酸酯(H4L3),(5,5'-(萘基-1,6-萘基基)二间苯二甲酸酯(H4L4) )和5,5'-(-2,6-萘基萘基)二间苯二甲酸酯(H4L5)已用于生成五种基于铜的MOF异构体。正如单晶X射线衍射研究所揭示的那样,他们根据有机配体采用了两种不同类型的拓扑:分别基于配体H4L1和H4L4的MOF ZJNU-71和ZJNU-74的ssa拓扑以及nbo拓扑分别衍生自配体H4L2,H4L3和H4L5的MOF ZJNU-72,ZJNU-73和NOTT-103。此外,系统地研究了它们对C2H2的吸附性能,发现它们具有不同的C2H2吸收能力,这
