我们提出并验证了一种简单的顶点连接策略，该策略可用于框架设计和孔径/类型调制，以制备一个母结构和另外10个具有前所未有拓扑结构的高多孔等纵框架。重要的是，潜在可达孔隙体积（57-71%），孔隙大小(6.8-11。2;17.0 - -29.0;12.5 - -22.8;11.9-24.5 Å)，同时系统地调整了这一系列高孔隙框架的孔隙形状。有趣的是，IIa [zn40o (L(2))2(BDC)0.5]{(CH3)2NH2}的孔径减小幅度略小于IIc [zn40o (L(2))2(2,6- ndc)0.5]{(CH3)2NH2}；但其对CH4的选择性提高了近2倍。
We propose and validate a simple strategy of vertex connection that can be used for framework design and pore size/type modulation to prepare a mother structure and another 10 highly porous isoreticular frameworks with unprecedented topology. Importantly, the potential accessible pore volumes (57-71%), pore sizes (6.8-11. 2 Å; 17.0-29.0 Å; 12.5-22.8 Å; 11.9-24.5 Å), and the pore shapes of this series of highly porous frameworks were simultaneously and systematically tuned. Interestingly, the pore size of IIa [Zn4O(L(2))2(BDC)0.5]{(CH3)2NH2} decreased a little less than that of IIc [Zn4O(L(2))2(2,6-NDC)0.5]{(CH3)2NH2}; however, its selectivity of CO2 toward CH4 increased by almost two times.
