Abstract Fluorescence properties of mixed‐ligand zinc(II) complexes may be affected by the interactions between different ligands, resulting in more complex fluorescence behavior due to discrepancy energy levels. In this paper, three complexes: {[Zn 2 (L 1 ) (CO 3 )](H O)} n ( ), [Zn(L )(H O) ] and [Zn 8 4 (H were obtained using 3‐amino‐1,2,4‐triazole (HL 5‐hydroxyisophthalic acid L as organic linkers.

The solvothermal reactions involving cobalt ions with 5-methylisophthalic acid (H2MIP) and 1,3-bis(2-methylimidazol)propane (BMIP) yielded two cobalt(II) organic frameworks: {[Co4(MIP)4(BMIP)3]·1/2DMA}n (SNUT-31) {[Co4(MIP)4(BMIP)3]·(EtOH)2·H2O]}n (SNUT-32) where DMA represents N,N-dimethylacetamide EtOH signifies ethyl alcohol. Single-crystal X-ray diffraction analyses reveal that SNUT-31 SNUT-32 possess an isomorphic structure, featuring a unique 2-fold interpenetration of 3D frameworks in parallel manner. Notably, both demonstrate remarkable performance electrocatalytic oxygen evolution exhibit exceptional photocatalytic degradation capabilities against model comprising three distinct dyes: rhodamine B, methyl orange, blue.

We have demonstrated a single‐crystal‐to‐single‐crystal (SCSC) transformation from two‐dimensional noninterpenetrated layer to microporous three‐dimensional fourfold interpenetrated MOF. The centrosymmetric [Co 2 (μ ‐OH)(EIBA) 3 ] n ( SNUT‐25 ) transforms into [Co(EIBA) SNUT‐26 ), which is triggered by the reaction time with DMF that acts as structure‐directing agent (HEIBA = 4‐(2‐ethyl‐1H‐imidazol‐1‐yl)benzoic acid; N,N′‐dimethylformamide). Despite distinct structure and coordination arrangements of in contrast , both Co‐MOFs were synthesized using same ligand. Fascinatingly, upon introducing specific quantity combined negligible proportion nitric acid, will progressively completely transform . Under synergistic induction solvent molecules temperature, changed original layered pore In addition, are efficient photocatalysts for degradation organic dye methyl blue (MB) under visible light irradiation. Surprisingly, rates can reach over 96%. also exhibited high electrocatalytic oxygen evolution reaction.
