1D Magnetic Nickel‐Carbon Matrix Nanotube Composites Derived from Hydrogen‐Bonded Organic Frameworks and Metal–Organic Frameworks for Electromagnetic Wave Absorption

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 6, 2024

Abstract Hydrogen‐bonded organic frameworks (HOFs) and metal–organic (MOFs) emerge as promising materials for electromagnetic wave (EMW) absorption, due to their high specific surface area readily modifiable characteristics. In this study, 1D magnetic nickel‐carbon matrix nanotube composites (Ni‐HMCNTs) from a mixture of HOFs MOFs (Ni‐HMNTs) EMW absorption are synthesized. The Ni‐HMNTs achieved via one‐step method involving single‐pot solvothermal reaction among melamine, trimeric acid, nickel nitrate. This process involves HOF‐to‐MOF transformation, characterized by the penetration Ni ions into HOF structure competitive coordination reaction, resulting in hollow Ni‐HMNTs. Subsequent calcination yields Ni‐HMCNTs optimized absorption. Remarkably, with filling degree only 10 wt%, 1.2 Ni‐HMCNTs‐700 (heat‐treated at 700 °C) exhibits exceptional properties, minimum reflection loss ( RL min ) value −50.4 dB maximum effective bandwidth (EAB) 7.32 GHz (10.64–17.96 GHz). These findings pave way further exploration magnetically modified HOFs/MOFs applications.

Heterostructure of Hydrogen‐Bonded Organic Frameworks for White Light Emission and Information Encryption

Advanced Optical Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 25, 2024

Abstract Two dumbbell‐shaped building blocks (TMB and TMBT), featuring methyl benzoate groups as hydrogen bond units, are selected to construct heterostructures of HOFs, aiming achieve multiple functions including white luminescence, stimulus‐response behavior, well application in information encryption. TMB molecules self‐assembled form a flexible HOF (X‐HOF‐8) p‐xylene, containing solvent channels blue fluorescence. Upon removal guests, it can transform into nonporous crystal with gray In contrast, TMBT forms guest‐free (X‐HOF‐9) displaying orange They could bulk heterojunction (BHJ) HOFs energy transfer from TMBT, exhibiting composition‐dependent fluorescent color. Notably, emission be achieved BHJ converted fluorescence upon guest removal; subsequently, is restored re‐capturing guests. Furthermore, rod‐like triblock (THJ) also constructed, which exhibit regulatory behavior response gaining or losing The unique luminescent characteristics stimulus responsiveness these make them an excellent platform for applications anticounterfeit. This represents the pioneering achievement light HOF, groundbreaking realization THJ remarkable exciting characteristics.
