Metal–Organic Framework Nanoparticles

Abstract

Due to their well-defined 3D architectures, permanent porosity, and diverse chemical functionalities, metal-organic framework nanoparticles (MOF NPs) are an emerging class of modular nanomaterials. Herein, recent developments in the synthesis and postsynthetic surface functionalization of MOF NPs that strengthen the fundamental understanding of how such structures form and grow are highlighted; the internal structure and external surface properties of these novel nanomaterials are highlighted as well. These fundamental advances have resulted in MOF NPs being used as components in chemical sensors, biological probes, and membrane separation materials, as well as building blocks for colloidal crystal engineering.

“…Ihre vorhersagbaren Struktur-Eigenschafts-Beziehungen und die modulare Synthese haben MOFs [221][222][223] als eine der am intensivsten untersuchten Klassen von Polymernetzwerken fürp otenzielle Anwendungen auf Gebieten wie Gasspeicherung und -trennung, [224] Katalyse, [225] Wirkstofffreisetzung, [226] Lumineszenz und Sensorik, [227] Elektrizitätsleitung [228] und Ionentransport [229] [232] COF-102 hatte eine große Oberfläche (3472 m 2 g À1 ).…”

“…Nevertheless, MOFs have a couple of drawbacks. Firstly, metal oxides/carbon materials derived by MOFs are particle‐like form . To stick the particles by nonconductive polymer binder in electrode preparation process will lead to ‘invalid volume’, which complicates the ion diffusion and rises interfacial resistance .…”

MOF@PEDOT Composite Films for Impedimetric Pesticide Sensors

“…Having in mind that zeolites perform poorly in aqueous environments for the adsorption of uncharged or large organic compounds, while carbons excel with large nonpolar adsorbates; it is expected that IMZ would sit outside the range where good adsorption performance can be expected using either of the above-mentioned adsorbents. [23,24] The use of many MOFs was extensively explored regarding its possible applications in water-based separations and chromatography, [25][26][27][28] provided that selected materials fulfill the crucial requisite of stability toward hydrolysis. [20][21][22] MOFs can be generally described as microporous crystalline solids with high surface area and very versatile surface chemistry, constructed from coordination of metal ions (or clusters containing metal ions), linked with multi-dentate organic molecules.…”
