摘要：

An exceptional anionic porous framework CPF-13 that integrates multiple desirable features such as nanoscopic polyhedral cages, framework functionalization by amino groups, and charged framework, was reported. CPF-13 was obtained in high yield as colorless octahedral crystals via solvothermal reaction between zinc nitrate, DATRZ and BDC in DMF at 90°C. Results show that the presence of the mixed triazole-ccarboxylate trigonal bipyramidal SBU-2 helps overcome the shape limitation and leads to the formation of this unique polyhedral cage in CPF-13. Thermogravimetric analysis shows that the removal of solvent molecules occurs in the temperature range of 40-220°C and there is no further weight loss up to approx 300°C. Results suggest that CPF-13 has an optimum pore size to sustain the stability of the porous framework while exhibiting a high porosity for the gas uptake.
