MOF positioning technology and device fabrication

Abstract

Metal organic frameworks (MOFs) offer the highest surface areas per gram of any known material. As such, they epitomise resource productivity in uses where specific surface area is critical, such as adsorption, storage, filtration and catalysis. However, the ability to control the position of MOFs is also crucial for their use in devices for applications such as sensing, delivery, sequestration, molecular transport, electronics, energy production, optics, bioreactors and catalysis. In this review we present the current technologies that enable the precise positioning of MOFs onto different platforms. Methods for permanent localisation, dynamic localisation, and spatial control of functional materials within MOF crystals are described. Finally, examples of devices in which the control of MOF position and functionalisation will play a major technological role are presented.

Ammonia Adsorption and Co-adsorption with Water in HKUST-1: Spectroscopic Evidence for Cooperative Interactions

“…[1][2][3][4][5][6][7][8][9][10] MOFs are porous materials composed of metal centers, or nodes, connected with organic components to form threedimensional ordered networks. MOFs exhibit large surface areas, high porosity, and structural tunability by varying the attached linkers and metal nodes to modify the pore chemistry.…”

Bilayer Porphyrin-Graphene Templates for Self-Assembly of Metal-Organic Frameworks on the Surface

“…[10][11][12][13][14] Для многих из этих областей требуется, чтобы металлорганические каркасы формировались в виде тонких пленок на твердых подложках, а также мембран, что объясняет большой интерес к разработке способов получения и исследованию структуры и свойств этого типа МОК. Особые свойства таких иммобилизованных на поверхности систем, отличающие их от объемных Bilayer Porphyrin-Graphene Templates Другой давно и хорошо известный метод сборки, популярность и полезность которого периодически и резко возрастают с появлением новых классов со-единений, типов материалов, областей применения -это метод Ленгмюра-Блоджетт.…”

Advanced Fabrication Method for the Preparation of MOF Thin Films: Liquid-Phase Epitaxy Approach Meets Spin Coating Method

“…Noticeably, the deployment of such advanced methods would allow for the effective integration of the unique chemical and physical properties of MOFs, e.g. pore space, functionality, charge, etc., [9][10][11] into state-of-the-art devices leading to new electronic, photonic, and catalytic systems. It is to mention that serval research groups, including ours, had recognized the potential of MOF thin films in many key applications and thus the ongoing development of different MOFs thin film fabrication methods.…”

“…[9][10][11] Markedly, MOF thin films prepared on a functional surface, e.g. interdigitated capacitive or quartz crystal electrodes, would permit the introduction of numerous sensory transduction mechanisms in response to the interactions between the sorbed gas and the deposited host porous material.…”
