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.

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
