“…By taking advantage of the varied functional groups, such as self-assembled monolayers (SAMs) with different end groups, the specific orientation of growing MOFs on the different surfaces was realized and studied by Wöll and coworkers. 7,[30][31][32][33][34] Although the LBL technique provides good control of the film orientation and crystallinity, the oriented directions of the MOF thin films prepared by the LBL technique usually depend on the speciation of the SAMs and require solid supports. Kitagawa et al combined the Langmuir-Blodgett (LB) method with the LBL technique for MOF thin film deposition.…”

Metal-organic frameworks (MOFs) hold tremendous promise for various academic and industrial applications because of their structural merits (e.g., high surface areas, enormous porosity, and regular order). Recently, processable MOF films have been sought for application in various technologies, from separation to sensor devices. Essentially, MOFs deposited as thin films, with thicknesses ranging from nanometres to micrometres, low roughness and high homogeneity, are important for practical use and application-specific configurations, particularly in sensors and electric devices. Several innovative scientific methods have been developed for preparing MOF thin films. Among these methods, the electrochemical method is advantageous because it requires mild preparation, uses a short growth time, is easy to scale up and allows for controlling the phase/morphology and thickness by altering voltages in of the process of fabricating uniform and dense MOF thin films. This review focuses on recent developments of electrochemical methods for forming metal-organic framework thin films (e.g., preparation, growth mechanisms and characterization techniques) and their corresponding applications in sensing and micro-pattern devices and identifies the challenges that must be overcome.

“…[15][16][17][18][19] It is generally accepted that, independent of the deposition method, the key for the growth of homogeneous and highly oriented SUR-MOFs is the suitable adjustment of the surface chemistry,asit determines the interactions between the MOF structure and the surface.Avery convenient method to control the surface chemistry is the use of self-assembled monolayers (SAMs), which can be tailored to expose av ariety of functional groups.

As well-oriented, surface-bound metal-organic frameworks become the centerpiece of many new applications, ap rofound understanding of their growth mode becomes necessary.This work shows that the currently favored model of surface templating is in fact as pecial case valid only for systems with am ore or less cubic crystal shape,w hile in less symmetric systems crystal ripening and minimization of surface energies dominate the growth process.

“…In recent years, much attention has been paid to techniques of fabricating MOF thin films for practical applications such as membranes and gas sensors . From the viewpoints of efficient use of the pores of MOFs and functionality integration (heterosystem comprising different MOFs), precise control of the film thickness and growth direction are required.…”

Emergence of Surface‐ and Interface‐Induced Structures and Properties in Metal–Organic Framework Thin Films

2018

Metal–organic frameworks (MOFs) are of particular interest to researchers because of their structural diversity and variety of properties. MOF thin films have been intensively investigated for potential applications such as membranes, gas sensors, catalysts, etc. Although most MOF thin films have almost the same structure and properties as their bulk, some MOF thin films show remarkable structural changes and hidden properties that are not observed in the bulk. These phenomena would be induced by the surface and the interface. Recent improvements in thin‐film fabrication methods enabled us to construct MOF thin films and discuss the properties based on the structure, thickness and crystalline orientation in detail. This microreview describes and discusses the fascinating nature of MOF thin films originating from surface/interface. This paper is expected to help with the construction of a research strategy for MOF thin films to obtain hidden structures and properties of MOFs that are not observed in their bulk.
