Abstract It is still challenging to directly recognize the anionic species [UO 2 (CO 3 ) ] 4− , dominant in environment (82%‐93%), using current optical probes because of adverse effects its thick hydration shell on binding interactions. In this study, a water‐soluble Pt(II) methylated terpyridine complex ([Pt(CH ‐tpy)NCO] + supramolecular probe designed target by new strategy overlapping arrangement. The response demonstrates excellent selectivity among ≈30 investigated interfering substances, along with rapid (≈15 s), high sensitivity (64.1 n m and dual‐signals. confirmed both experimentally theoretically that superior detection performance attributed formation unique structure featuring biplane‐like building block, bicolumnar stacking water‐bridged networks, via overlap shells aligned boost superentropic driving force, distinguishable dual‐signals arises from emergence four types Pt‐Pt interactions, generating low‐energy metal‐to‐metal charge transfer adsorption/emission. addition, [Pt(CH ‐based hydrogel platform constructed for detecting cationic uranium, limit 14.89 fg. This work unlocks not only way detect but also idea sensing ions extreme layers.

The sensitive detection of the radioactive thorium (Th) ion with an oxidation state +4 (Th4+) is great significance for environmental protection and life safety. In this study, five fluorescence sensors regulated donor-acceptor (D-A) interactions were constructed Th4+ based on intramolecular charge transfer aggregation-induced emission mechanisms. Among developed sensors, TPE-D bearing electron-deficient π-bridge weak D-A presented ratiometric behavior toward in aqueous solution due to its characteristics unique D-A-D structures. Moreover, showed excellent selectivity sensitivity detection, limit was as low 8.1 × 10-8 M. sensing mechanism observation revealed that could coordinate hydroxyl, imine, carbonyl groups accompanied by electron process. addition, selectively be enriched lysosome. Both lysosome liver mice zebrafish realized strategy, a mobile-assisted approach actual water samples also established high sensitivity. This first report organelles organs, which provides reliable strategy radionuclide toxicology analysis applications.

Since their discovery, metal–organic frameworks (MOFs) and covalent organic (COFs) featuring permanent nanopores have transformed the landscape of porous materials, excelling as platforms for catalysis, gas separation, sensing thanks to exceptional surface areas, adjustable pore sizes, modular functionality. However, MOFs, while versatile, face stability challenges due coordination bonds, whereas COFs, although robust, lack metal sites, limiting catalytic activity, redox functionality, other metal-specific applications. To bridge these gaps, innovative such MCOFs, which incorporate ions into COF lattices; cluster frameworks, formed by assembling clusters networks; MOF–COF composites, integrate strengths both systems, emerged. This review explores synthesis design principles advanced showcasing applications unique advantages conferred composite nature. It provides insights future directions potential address key in materials science beyond.

Uranium plays an important role in the modern nuclear industry. However, such a radioactive element can also cause severe damage to environment once leaked or discharged into water air, having huge impact on safety of biosphere. In this work, we pioneered use fluorescent monomers as imprinted units, which promoted fluorescence emission material. A novel porous aromatic framework was obtained with uranyl ion chelating sites, namely MIPAF-15. The unique N-O pockets 4-bromo-1-H-indole-7-carboxylic acid gave rise high coordination affinity toward ions, enabled fast adsorption rate ions and capacity 44.88 mg·g−1 at 298 K initial pH value 6.0 concentration 10 ppm. At same time, quenching effect MIPAF-15 observed upon its allowed selective detection limit 5.04 × 10−8 M, lower than maximum drinking specified by World Health Organization (6.30 M) United States Environmental Protection Agency (1.11 10−7 M). This kind multifunctional material produces favorable pathway for detection, removal degeneration highly pollutive promoting overall sustainable development natural environment.
