We demonstrate herein an all-optical switch based on stimuli-responsive and photochromic-free metal-organic framework (HKUST-1). Ultrafast near-infrared laser pulses stimulate a reversible 0.4 eV blue shift of the absorption band with up to 200 s-1 rate due dehydration concomitant shrinking structure-forming [Cu2 C4 O8 ] cages HKUST-1. Such light-induced switching enables remote modulation intensities photoluminescence single crystals HKUST-1 as well visible radiation passing through crystal...
Abstract Structural transformations of metal-organic frameworks (MOFs) go through a complex energy landscape with multiple intermediate states. Although the allow controlling functional properties MOFs, an imbalance between MOF flexibility and rigidity sets fundamental barrier to achieving fast transformations. Here, we study stimuli-responsive structural transformation in 2D assembled from paddle-wheel secondary building units joined by semi-flexible organic ligand 1,2,4-triazole...
Abstract Direct laser writing (DLW), being a universal tool for fast creating colorless/color images on different substrates, still suffers from simultaneous grayscale and color inside the transparent media. Here, it is discovered that unique set of porosity, coordination bonding between organic inorganic building blocks, lack inversion symmetry label‐free metal‐organic frameworks (MOFs), one hand, provides possibility through amorphization/carbonization. On other reduction power leads to...

Polymers with embedded metal–organic frameworks (MOFs) have been of interest in research for advanced applications gas separation, catalysis and sensing due to their high porosity chemical selectivity. In this study, we utilize specific MOFs thermal stability non-centrosymmetric crystal structures (zeolitic imidazolate framework, ZIF-8) order give an example MOF–polymer composite nonlinear optics. The synthesized MOF-based polymethyl methacrylate (PMMA) (ZIF-8–PMMA) demonstrates the...
Laser interference patterning on top of a thin film and inside crystal is powerful tool today to create the desired patterns for optical data processing. Here, we demonstrate reversible irreversible laser metal-organic framework (MOF) through water desorption thermal decomposition processes, respectively. The pattern with period strips up 5 µm has been realized, its morphology characterized using confocal Raman reflection spectroscopy as well atomic force microscopy. We revealed that...
Metal-organic frameworks (MOFs) form a unique platform for operation with data using ReRAM technology. Here we report on large-scale fabrication of MOF-based array 6 × cells, demonstrating 50% variation in their electronic parameters. Despite this inhomogeneity, such "non-ideal" is used recording binary information followed by deep learning processes to achieve 95% accuracy reading. Next, the same record numbers (from 0 15) addition. For correct performance an analogue algorithm, determine...
