The synthesis of metal-organic frameworks (MOFs) often involves high-boiling-point organic solvents, which can have extensive environmental impact and limit their large-scale applications. Here, we present a one-pot aqueous-phase approach for the rapid preparation 33 trinuclear-copper-cluster-based MOFs (1 to 33) with different pyrazoles under ultrasonic irradiation. To address water-solubility challenge linkers, employ aromatic amines/aldehydes pyrazole aldehydes/amines in situ generate imine-based pyrazoles. This linker dismantling strategy enables formation low-concentration pyrazoles, are essential assembly aqueous phase. use preassembled trinuclear gold complexes instead amines affords an Au-Cu-based MOF (34) alternating copper clusters, rare example mixed yet precise arrangement metal compositions. Additionally, direct addition pyruvic acid reaction mixture results facile carboxylic-acid-functionalized (35), eliminating need preinstallation or postmodification steps traditional synthesis. Furthermore, demonstrate 11-AA as efficient photocatalyst cross-dehydrogenative coupling (CDC) reactions, exploiting synergetic effect substrate activation on sites subsequent initiated by photosensitive linkers. work offers simple solution making minimal impact; it also opens up possibilities developing multifunctional diverse

Abstract The development of porous solids for gold recovery is highly desired from both an economical and environmental point view; however, the design solid adsorbents with high overall performance still challenging. Herein, we designed three copper(I) cyclic trinuclear units, Cu(I)‐CTUs, based covalent metal‐organic frameworks (CMOFs) by networking metal clusters dynamic linkages. These CMOFs deliver a adsorption capacity 3687 mg g −1 , ultra‐fast kinetics (i.e., removal efficiency > 99% within 20 s), excellent selectivity reusability. In addition, they can be readily used extraction e‐waste. Owing to rich redox properties Cu‐CTUs, these show sorption mechanisms including adsorption, chemical reduction photocatalytic reduction. Interestingly, gold‐loaded as catalysts hydration alkynes ketones yields (e.g., up ∼ 95% 6 examples).

Radiotherapy, as an important means of treating hepatocellular carcinoma (HCC), has shown unique therapeutic advantages, especially in patients who are unable to undergo surgery or transplantation. It mainly includes external radiotherapy, transarterial radioembolization and intratumoral radioactive particle implantation. However, under the influence factors such hypoxic characteristics liver tumor microenvironment radioresistance cells, effect radiotherapy may be unstable cause side effects, affecting quality life patients. In recent years, with development nanotechnology, drug delivery systems based on micro-nanomaterials have provided new solutions for improving HCC. Despite this, application micro-nano treatment HCC still faces some challenges, including vivo safety metabolism materials. This article reviews latest progress materials HCC, their radiosensitization clinical translation potential. systematically analyzes role internal sensitization radioimmunotherapy explores advantages
