Coordination polymer particles with high degree of porosity are promising for diverse applications. Downsizing to nanoscale, this class of materials is of great interest due to the size-, shape-, and composition-dependent properties. We are reporting a noble Zn-based coordination polymer nanocubes (Zn-CPNs). The solvothermal synthetic protocol for ZIF-8 is employed, and 2,6-bis[(4-carboxyanilino)carbonyl] pyridine (N3) ligand is additionally coupled. Importantly, N3 ligand works as a shape-directing modulator, to change the size and shape of Zn-CPNs in a controllable fashion. The average dimension of Zn-CPNs is 156 ± 14 (nm) and the size is narrowly dispersed. The synthesized Zn-CPNs show high specific surface area (ca. 2100 m2g-1). The N3 ligand in Zn-CPNs can be used for the coordination of other metal ions than ZnII. In a further step, gas storage and catalysis performances of Zn-CPNs as well as theirs derived metathesis in Zn-CPPs are also investigated. |
