Secondary interaction-manipulated metal–organic crystalline nanotube array for gas sensing

Abstract

Although having attracted growing interest, design and preparation of metal-organic crystalline nanotube array (MO-CNA) remains a challenge. Herein, Pb···S metal-nonmetal secondary interaction strategy was proposed to prepare a Pb(II)-based MO-CNA...

Bi-metallic [Cu/Co(6mna)2]n metal organic chalcogenolate frameworks as high-performance electro-catalysts for dye-sensitized solar cells: a ligand-assisted bottom-up synthesis

“…Metal–organic frameworks (MOFs) have been extensively investigated as superior electro-catalysts for various electrochemical devices, including water splitting devices, 1 supercapacitors, 2 sensors 3–5 etc. Within a MOF architecture, the unsaturated coordination at metal clusters is considered as active sites to trigger numerous electrochemical reactions, while the adjustable organic ligands are expected to deliver variable pore configurations and functionalities for specific molecules.…”

Eu(III) Guests Sensitized by a Metal–Organic Framework for Sensing Cr(VI) in Strong Acids

“…Since its debut in 2009, , the linker molecule H 2 DMBD (2,5-dimercaptobenzenedicarboxylic acid) has opened two directions for coordination network [also known as the metal–organic framework (MOF)] materials. On one hand, transition metal ions (e.g., M = Cu + , Fe 2+ , Co 2+ , and Ni 2+ ) and other soft metal ions (Pb 2+ ) engage the thiol groups (−SH) to form solid frameworks with enhanced conductive and electroactive properties. − Highlights here include the 2D system M 2 DMBD reported in 2022, − which was also shown to be amenable with ion intercalations between the metal–thiolate layers, so as to conveniently modify the electronic and redox properties . On the other hand, very hard metal ions (e.g., Eu 3+ , Al 3+ , and Zr 4+ ) selectively engage the carboxyl units to form open frameworks (e.g., the now commercialized ZrDMBD solid), with free-standing mercapto groups for functionalization.…”

Array-Designed Triboelectric Nanogenerator for Healthcare Diagnostics: Current Progress and Future Perspectives

“…Environmentally, AD-TENGs are favorable due to their reliance on non-toxic materials, making them more sustainable. Lastly, their versatility in energy harvesting from various mechanical movements, including human motion and natural elements like wind and water, makes them highly adaptable for diverse applications [45][46][47][48]. These attributes collectively position AD-TENGs as highly effective and versatile for a range of applications, particularly in healthcare diagnostics and wearable technology.…”
