Ribbon-like coordination polymers (CP) represents a highly unexplored innovative class of metal-coordination network. Herein, we have developed scalable and chemically robust (pH=3-10 stable) ribbon-like CP [{Cu(Pim)(L)(H2O).H2O}]n (1) following complete environment-friendly green synthesis route. Considering the presence surface flanked labile coordinated water molecules their appealing correlation with one-dimensional structural characteristics, such sort was explored for first time as excellent heterogeneous catalyst largely three-component Hantzsch condensation different classes dihydropyridine (DHP). Moreover, 1 is employed to synthesize bio-responsive drug 'Ethidine' (possessing high anti-oxidant anticarcinogenic properties) characterized Single Crystal X-ray Diffraction (SCXRD) analysis. Several DHP-based products are also analysed through in-depth SCXRD This report inaugurates usage Cu(II) based CPs environmentally benign manner bioactive DHPs Drugs.

Abstract Metal‐cluster‐based covalent organic frameworks (MCOFs), obtained through connections between metal clusters and molecules, have shown considerable promise in many applications. However, MCOFs rarely been employed as triboelectric materials nanogenerators (TENGs), their corresponding effect on the output has not systematically elucidated. Here, for first time, a set of (Cu 3 ‐S‐MCOF, Cu ‐M‐MCOF, ‐L‐MCOF) having similar skeletons but different pore spaces (2.1, 3.4, 4.2 nm) are synthesized using copper‐cyclic trinuclear units. All utilized fillers methyl cellulose (MC) matrix to prepare series films layers TENGs. Kelvin probe force microscopy (KPFM) showed that surface charge density fabricated can be precisely altered based MCOFs. The mixing ratio MC is optimized boost outputs A very high current voltage up 54.8 µA 532.9 V, respectively, at 5 Hz from TENG with 10wt%Cu ‐M‐MCOF@MC, which further sensor monitor human motions. This study provides new insights into investigation MCOF tunable functionality achieve high‐performance devices.

Selected area electrochemical etching (EE) and deposition (ED) are widely used for fabricating microstructures devices, but they require complex processes expensive equipment generate significant electrolyte waste. This study demonstrates a novel single-droplet system using triboelectric nanogenerator (TENG) self-powered selected EE ED reactions. Utilizing TENG's pulsed power, Al nanostructures were created by EE, while nano-Ag Cu2O nanocubes synthesized ED. The generated nanomaterials applied to detect trace chemicals through the Surface-Enhanced Raman Scattering effect. reaction can be controlled droplet size, patterns needle movement platform. size density of adjusted current, collision frequency, concentration. gradient from center edge is distance between substrate. COMSOL Multiphysics calculations show that smaller D creates larger electric field gradient. However, varied gradients attributed competition field, diffusion effects, capillary flow. proposed green technology offers low cost, simplicity, no waste electrolyte, self-powering capabilities, pioneering new research directions in
