Hybrid Zeolitic Imidazolate Frameworks Controlling Framework Porosity and Functionality by a Mixed-Ligand Synthetic Approach

摘要

Metal-organic frameworks, in particular hybrid zeolitic imidazolate frameworks (ZIFs), devices having hybrid ZIFs, and methods for preparing hybrid ZIFs are disclosed herein. In some embodiments, the method includes preparing a first solution comprising a first imidazolate and a second imidazolate, preparing a second solution comprising a metal ion, and combining the first solution and the second solution to form the hybrid ZIF.
