A luminescent mixed lanthanide metal–organic framework approach has been realized to explore thermometers. The targeted self-referencing thermometer Eu0.0069Tb0.9931-DMBDC (DMBDC = 2, 5-dimethoxy-1, 4-benzenedicarboxylate) based on two emissions of Tb3+ at 545 nm and Eu3+ 613 is not only more robust, reliable, instantaneous but also higher sensitivity than the parent MOF Tb-DMBDC one emission a wide range from 10 300 K.
A highly selective and robust catalyst based on Pt nanoclusters (NCs) confined inside the cavities of an amino-functionalized Zr-terephthalate metal–organic framework (MOF), UiO-66-NH2 was developed. The NCs are monodisperse in even at 10.7 wt % loading. This confinement further confirmed by comparing catalytic performance supported external surface MOF hydrogenation ethylene, 1-hexene, 1,3-cyclooctadiene. benefit confining also demonstrated evaluating their chemoselective cinnamaldehyde.

A bifunctional Zr-MOF catalyst containing palladium nanoclusters (NCs) has been developed. The formation of Pd NCs was confirmed by transmission electron microscopy (TEM) and extended X-ray absorption fine structure (EXAFS). Combining the oxidation activity acetalization Lewis acid sites in UiO-66-NH2, this (Pd@UiO-66-NH2) exhibits excellent catalytic selectivity a one-pot tandem oxidation-acetalization reaction. This shows 99.9% to benzaldehyde ethylene acetal reaction benzyl alcohol glycol...
Control of heterogeneous catalytic sites through their surrounding chemical environment at an atomic level is crucial to catalyst design. We synthesize Pd nanoclusters (NCs) in atomically tunable using isoreticular metal–organic framework (MOF) supports (Pd@UiO-66-X, X = H, NH2, OMe). In aerobic reaction between benzaldehyde and ethylene glycol, these catalysts show product distributions that are completely altered from the acetal ester when we change functional groups on MOF linkers −NH2...

A new honeycomb-shaped electroactive metal-organic framework (MOF) has been constructed from an electron deficient naphthalenediimide (NDI) ligand equipped with two terminal salicylic acid groups. π-Intercalation of electron-rich planar tetrathiafulvalene (TTF) guests between the NDI ligands stacked along walls lowers electronic band gap material by ca. 1 eV. An improved delocalization through guest-mediated π-donor/acceptor stacks is attributed to diminished doped material, which forecasts...
Fluorescence (FL) imaging in the second near-infrared window (NIR-II, 1000–1700 nm) has emerged as a promising bioimaging modality that enables noninvasive visualization of deep tissue with an unprecedented resolution. However, there is paucity studies on high-quality responsive NIR-II FL molecules. Herein we report novel activated molecule, 4,7-bis(5-(4-(diphenylamine)phenyl)-2-thiophene) [1,2,5]selenadiazolo[3,4-f]benzo[c][1,2,5]thiadiazole (SeTT), which exhibits fast and specific...
Covalent organic frameworks (COFs) represent an emerging class of two- or three-dimensional crystalline porous materials with delicate control over topology, composition, and porosity. Here, we develop a new COF made up 1,3,6,8-tetrakis(p-formylphenyl)pyrene (TFPPy) 4,4′-diaminobenzophenone (DABP) that exhibits rare one-dimensional (1D) structure. The resulting possess good crystallinity, comparatively high Brunauer–Emmett–Teller (BET) surface area (426 m2/g), thermal stability (360 °C)....
Covalent organic frameworks (COFs) have been extensively investigated due to their unique structure, porosity, and functionality. However, at the topological level, COFs remain as two-dimensional (2D) or three-dimensional (3D) structures, while with one-dimensional (1D) topology not systematically explored. In this work, we proposed a synthetic strategy for construction of 1D-COFs based on non-linear edges suitable high-symmetry vertices. Compared 2D-COFs counterparts, AIEgens located vertex...
P450 TleB catalyzes the oxidative cyclization of dipeptide N-methylvalyl-tryptophanol into indolactam V through selective intramolecular C–H bond amination at indole C4 position. Understanding its catalytic mechanism is instrumental for engineering or design P450-catalyzed reactions. Using multiscale computational methods, we show that reaction proceeds a diradical pathway, involving hydrogen atom transfer (HAT) from N1–H to Cpd I, conformational transformation substrate radical species, and...
Abstract Skeletal disorders are commonly diagnosed by X-ray imaging, but the radiation limits its use. Optical imaging through near-infrared-II window (NIR-II, 1000–1700 nm) can penetrate deep tissues without risk, targeting of contrast agent is non-specific. Here, we report that lanthanide-doped nanocrystals passively target bone marrow, which be effective for over two months. We therefore develop high-resolution NIR-II method disease diagnosis, including 3D instrumentation to show...

The development of probes for early monitoring tumor therapy response may greatly benefit the promotion photodynamic (PDT) efficacy. Singlet oxygen (1 O2 ) generation is a typical indicator evaluating PDT efficacy in cancer. However, most existing cannot quantitatively detect 1 vivo due to high reactivity and transient state, thus have poor correlation with response. Herein, -responsive theranostic platform comprising thiophene-based small molecule (2SeFT-PEG) photosensitizer Chlorin e6...
