Abstract:

Metal-organic frameworks (MOFs) as a kind of inorganic-organic hybrid materials have potential applications in many fields due to their diverse structures and unique functionalities. In particular, liquid phase epitaxial layered MOFs films (called SURMOFs films, SURMOFs) have attracted much attention due to their controllable thickness, optimal growth orientation and uniform surface. This article summarizes the liquid phase epitaxy (LPE) layers of assembly MOFs thin film technology and methods, such as layer-by-layer (LBL) dipping method, LBL pump method, layer spray method and LBL spin coating method. The article also introduces the classical SURMOF layers of HKUST-1 assembly strategy and its related applications in photoluminescence, photochromic, photocatalytic and electrocatalysis. As one of the classical MOF materials, HKUST-1 has a wide range of applications in photoelectric field, and it has the unique properties: it can be used as a luminous carrier to achieve good optical properties; it has the advantage of unique Cu catalytic active site and can effectively degrade pollutants; it has potential applications in electronic devices because of its dielectric properties. Since SURMOF HKUST-1 has unique properties in many fields, it also faces some challenges: it needs to simplify the process of film synthesis; the structure of thin films and the mechanism of electrocatalysis also need further study; methods for reducing HKUST-1 internal resistance which can increase the conductivity also need to be improved. SURMOFs still has a long way to go for large-scale industrial applications and expansion to other unexplored areas.
