Photocatalytic water splitting for hydrogen production holds considerable potential simultaneously addressing fuel and carbon neutrality, although increasing photocatalyst activity enhancing exciton dissociation continue to be very difficult tasks. Covalent organic frameworks (COFs) with predesignable structures customizable functionalities are promising candidates photocatalysis. In this study, we present the design synthesis of these COFs using thiazole rings as linkage units. Three (denoted COF-S-OH-1, COF-S-OH-2, COF-S-OH-3) were prepared based on aldehyde ligands varying numbers hydroxyl groups (2-hydroxybenzene-1,3,5-tricarbaldehyde, 2,4-dihydroxybenzene-1,3,5-tricarbaldehyde, 2,4,6-trihydroxybenzene-1,3,5-tricarbaldehyde, respectively). The results demonstrate that constructed linkages exhibit superior stability conjugation compared those linked solely by imine bonds, ultimately achieving enhanced electronic conductivity. tight interaction between donor acceptor in donor-acceptor (D-A) system facilitates an improved photocatalytic evolution performance. Furthermore, number (electron-donating groups) significantly enhances efficiency resulting COFs.

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.
