以5,6-二甲基苯并咪唑和咪唑为配体，Zn(NO3)2为金属盐，采用水作为溶剂合成了一种具有 GIS 拓扑结构的沸石咪唑酯骨架（ZIFs）材料 TIF-5Zn。研究了反应溶剂（水、甲醇、甲醇-氨水）对材料形貌的影响以及材料的化学稳定性和热稳定性，并用 XRD、SEM、TG 及 CHN 元素分析等手段对材料进行了表征。结果表明：溶剂对其形貌有显著的影响，在单一溶剂水或甲醇中只能形成不规整的微/纳米颗粒聚集体，而在甲醇-氨水混合溶剂中得到了形貌规整的微球状 TIF-5Zn，它是由亚微米粒子组装而成的多级微米球结构。

Using 5,6-dimethylbenzimidazole and imidazole as ligands,Zn(NO3)2 as metal salt and water as solvent,ZIFs material TIF-5Zn with GIS topology was synthesized by solvothermal method. The influence of solvent on morphology and the stability of TIF-5Zn were investigated with XRD, SEM,TG and CHN. The results showed that solvent had great influence on morphology of the samples. Water or methanol as a single solvent generated irregular shaped aggregates of micro or nanocrystals, while based on the mixed solvent of aqueous ammonia (NH3·H2O) and methanol (CH3OH),highly ordered TIF-5Zn could be obtained. This multi-level microspheres consisted of ordered assembly of numerous submicron particles.
