Colloidal Route for Preparing Optical Thin Films of Nanoporous Metal–Organic Frameworks

Abstract

Colloids of a highly flexible porous metal-organic framework (MOF) have been prepared using nontoxic and easily removable solvents. Furthermore, a simple dip-coating method for the preparation of optical-quality thin films of the MOF has been developed. The homogeneous thin film exhibits reversible flexibility, as has been proven by environmental ellipsometry.
