Metal-organic frameworks (MOFs) are hybrid materials consist of inorganic metal centers connected by organic linkers. This nature gives MOFs synergetic properties of both inorganic and organic porous materials. Due to their thermal and chemical stability, high surface area, low densities, designable framework, sorption capacities and functionality, MOFs are such a widely growing field for many different applications that in the past decade, more than 20,000 different MOFs have been reported and studied1. In particular, the availability of preparation of thin MOF films will open new doors in terms of applications such as membranes, gas separation, catalytic coatings, optical coatings and sensors for MOFs2. Therefore developing techniques to prepare thin MOF films is recently attracting considerable attention of many researchers.
This project focusses on the preparation of continuous thin porous metal organic framework (MOF) films with different techniques that allow localized film formation. The aim is to make films with limited or no inter-crystalline porosity, for instance to increase the molecular selectivity of these layer in membrane applications.
