Metal-organic frameworks (MOFs), known for their exceptional gas permeability and abundant active sites, are a class of porous coordination polymers that can serve as ideal candidates constructing advanced sensors. However, the limitations low electrical conductivity inadequate stability under extreme conditions hinder advancements in gas-sensing applications. Moreover, single MOF structure occasionally demonstrates insufficient selectivity toward specific gases, failing to meet stringent sensing requirements. To overcome these challenges, this study innovatively constructs an MOF-on-MOF architecture by etching Ti-MOF into hollow cage-like with l-glutamic acid connecting it Ni2+ ions form Ni-MOF via peptide bonds. The approach not only enhances surface area pore material but also facilitates carrier transport rates at interface effectively linking two MOFs. resultant exhibits remarkable sensitivity detecting triethylamine operating temperature 140 °C, along reproducibility long-term stability. This work novel amino acid-assisted feasible simple method construct material, showcasing immense potential high-performance detection

Monochromatic Responsive HOF Heterostructures via VIA‐Group‐Based Framework Hybridization for Fully‐Covert Photonic Barcode

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 11, 2025

Abstract Luminescent responsive heterostructures with region‐domained emission and integrated responsiveness exhibit great potential in information security, but always suffer from the direct exposure of fingerprint at initial state, making it easy to decode hidden confidential information. Herein, first monochromatic hydrogen‐bonded organic framework (HOF) are reported based on VIA‐group‐based hybridization toward fully‐covert photonic barcodes. Designed HOF blocks different VIA‐group elements via a configuration‐assimilation‐based assembly method generate intrinsic heterostructures. Differentiated electronegativity endows each block distinct bonding stability, which triggers actions same stimuli, finally forming multicolor mode state. These can effectively hide information, further demonstrates coding capability as high‐security anti‐counterfeiting labels. findings offer novel insight exploitation smart‐responsive hetero‐HOF systems for advanced encryption anticounterfeiting applications.

Stepwise Epitaxial Growth of Core–Shell Organic Crystals for Advanced Dual-Emission Optical Applications

Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Апрель 24, 2025

Organic core-shell heterostructures (CSHs) offer a unique platform for integrating complementary properties of the core and shell materials, leading to an optimized multifunctional performance. However, growth mechanism within CSHs remains unclear due poor crystallographic compatibility between different components fast crystallization. This study elucidates detailed process fabricating organic crystalline with tunable morphologies through in situ epitaxial approach, by employing IDF-TCNB (CryDFNB) IDT-TCNB (CryDTNB) charge-transfer cocrystals. After lattice matching three dimensions is satisfied, CryDTNB epitaxially grows on CryDFNB surface along specific orientations, sequence determined differences attachment energy. The bilayer structure results distinct dual-emission optical properties, including differentiated polarization, dual-band quasi-whispering gallery mode resonance, waveguides. work provides new framework design synthesis controlled structures advanced photonic functionalities.
