The limited active sites and poor acid-alkaline solution stability of metal-organic frameworks (MOFs), significantly limit their wider application. In this study, the acid property tannic (TA) was used as an etchant to etch surface-active sites. Subsequently, further chelation protonated TA with exposed metal site can effectively protect ions. Meanwhile, provided a large amount phenolic hydroxyl groups, which greatly improve imidazolate-coordinated MOFs. electrochemical test results indicated that MOFs composite materials synthesized using scheme had high specific capacitance stability. And mechanism its reaction process explored through in situ X-ray diffraction (XRD) theoretical calculations. addition, same treatment carried out series carboxyl-coordinated MOFs, confirmed principle obtain higher This paper explains functionalization nano-MOFs by polyphenolic compounds, providing new ideas for research nano-MOFs.

Metal-organic frameworks (MOFs), formed by the combination of both inorganic and organic components, have attracted special attention for their tunable porous structures, chemical functional diversities, enormous applications in gas storage, catalysis, sensing, etc. Recently, electronic MOFs like electrocatalysis, supercapacitors, batteries, electrochemical etc., become a major research topic MOF chemistry. However, low electrical conductivity most represents handicap development these emerging applications. To overcome limitations, different strategies been developed to enhance implementation devices. In this review, we outline all employed increase conduction intrinsically (framework-modulated) extrinsically (guests-modulated) conducting MOFs.

The demand for monitoring chemical and physical information surrounding, air quality, disease diagnosis has propelled the development of devices gas sensing that are capable translating external stimuli into detectable signals. Metal–organic frameworks (MOFs), possessing particular physiochemical properties with designability in topology, specific surface area, pore size and/or geometry, potential functionalization, host–guest interactions, reveal excellent promises manufacturing a variety MOF-coated multitudinous applications including sensing. past years have witnessed tremendous progress on preparation sensors superior performance, especially high sensitivity selectivity. Although limited reviews summarized different transduction mechanisms sensors, summarizing latest under working principles would be good complement. Herein, we summarize advances several classes MOF-based sensing, i.e., chemiresistive capacitors, field-effect transistors (FETs) or Kelvin probes (KPs), electrochemical, quartz crystal microbalance (QCM)-based sensors. chemistry structural characteristics were carefully associated behaviors relevant Finally, challenges future prospects long-term potentially practical application pointed out.

Abstract Thin‐film fluorescent sensors play critical roles in the gas sensing field. However, materials for practical applications are limited, because of aggregation‐caused quenching (ACQ) effect and photobleaching. This study investigates a host–guest thin‐film fluorescence sensor by incorporating probe into metal–organic framework (MOF). The molecule Me 4 BOPHY‐1 acts as recognition neurotoxin analog diethylchlorophosphite (DCP). MOF (ZIF‐8) provides nanocavities confinement guest molecules, which reduces self‐aggregation molecules pre‐enriches target gas. By applying ZIF‐8 to disperse ACQ can be effectively overcome. quantum efficiency is increased from 0.76% 19.72%, enables its ability with fast response time 3 s detection limit low 1.13 ppb. Besides, facilitates selectivity enhancement through effect, weakening interference HCl. Moreover, also ensures high photo‐stability well thermal stability. It maintain intensity under 4800 s’ laser irradiation. Thus, design strategy offers 3S (sensitivity, selectivity, stability) toward analytes.
