The modular nature of metal–organic frameworks (MOFs) enables synthetic control over their physical and chemical properties, but it can be difficult to know which MOFs would optimal for a given application. High-throughput computational screening machine learning are promising routes efficiently navigate the vast space have rarely been used prediction properties that need calculated by quantum mechanical methods. Here, we introduce Quantum MOF (QMOF) database, publicly available database computed quantum-chemical more than 14,000 experimentally synthesized MOFs.

Abstract The ever‐increasing concerns over indoor/outdoor air quality, industrial gas leakage, food freshness, and medical diagnosis require miniaturized sensors with excellent sensitivity, selectivity, stability, low power consumption, cost‐effectiveness, long lifetime. Metal‐organic frameworks (MOFs), featuring structural diversity, large specific surface area, controllable pore size/geometry, host‐guest interactions, hold great promises for fabricating various MOF‐based devices diverse applications including sensing. Tremendous progress has been made in the past decade on fabrication of elevated sensitivity selectivity toward analytes due to their preconcentrating molecule‐sieving effects. Although several reviews have recently summarized different aspects this field, a comprehensive review focusing is absent. In review, latest advance relying transduction mechanisms, example, chemiresistive, capacitive/impedimetric, field‐effect transistor or Kelvin probe‐based, mass‐sensitive, optical ones are comprehensively summarized. making large‐area MOF films essential mass‐production relevant also included. compositional features MOFs intentionally correlated sensing performance.

Journal of the American Chemical Society, Год журнала: 2020, Номер 142(52), С. 21622 - 21627

Опубликована: Дек. 17, 2020

Two-dimensional conjugated covalent organic frameworks (2D c-COFs) are emerging as a unique class of semiconducting 2D polymers for (opto)electronics and energy storage. Doping is one the common, reliable strategies to control charge carrier transport properties, but precise mechanism underlying COF doping has remained largely unexplored. Here we demonstrate molecular iodine metal–phthalocyanine-based pyrazine-linked c-COF. The resultant c-COF ZnPc-pz-I2 maintains its structural integrity displays enhanced conductivity by 3 orders magnitude, which result elevated concentrations. Remarkably, Hall effect measurements reveal mobility reaching ∼22 cm2 V–1 s–1 ZnPc-pz-I2, represents record value c-COFs in both direct-current alternating-current limits. This phenomenon with increased upon can be traced scattering time free carriers, indicating that mechanisms limiting mitigated doping. Our work provides guideline on how assess effects COFs highlights potential display high conductivities mobilities toward novel (opto)electronic devices.
