Water soluble metal-organic frameworks (MOFs)

摘要

An efficient, one step solution state processing of Proton Conducting Homochiral Metal Organic Framework has been achieved by using derivate of amino acid and Zn(II) salt as a MOF constructor. Control over MOF solubility as well as proton conductivity has also been achieved by judicious selection of the ligand architecture. This invention will lead the way for ease preparation of MOF films for industrial application.
