Metal–organic frameworks attract great attention because they show potential for applications such as catalysis and luminescence sensing. Herein, a novel copper–organic framework, [Cu2.5(OH)(nia)2(Bibt)1.5]n, known CuBN, was hydrothermally prepared based on the self-assembly of 4,7-bis(1H-imidazole-1-yl) benzo-[2,1,3]thiadiazole (Bibt), 5-(1,8-naphthalimido)-isophthalic acid (H2nia), CuCl2·2H2O. CuBN exhibited 4, 8-connected sqc 3D porous framework with binuclear copper oxygen cluster unit point symbol {34 48 512 64}{32 42 52}. can work an efficient luminescent sensor Hg2+ via turn-on fluorescence change. Fluorescent data shows that has high selectivity to among various metal ions, detection limit is low, down 9.52 nM. The sensing behavior be mainly attributed Hg2+-promoted collapsing subsequent binding ligand Bibt. In addition, exhibits capability promoting chemical fixation CO2 cyclic carbonates under mild conditions (0.1 mol % catalyst loading, 2 TBAB, 1 atm CO2, 24 h, 80 °C without solvent) up 97% yield good reusability.

Developing a highly active catalyst that can efficiently capture and convert carbon dioxide (CO2) into high-value-added energy materials remains severe challenge, which inspires us to explore effective metal–organic frameworks (MOFs) with high chemical stability high-density sites. Herein, we report robust 3D lead(II)-organic framework of {(Me2NH2)2[Pb5(PTTPA)2(H2O)3]·2DMF·3H2O}n (NUC-111) unreported [Pb10(COO)22(H2O)6] clusters (abbreviated as {Pb10}) nodes (H6PTTPA = 4,4′,4″-(pyridine-2,4,6-triyl)triisophthalic acid). After thermal activation, NUC-111a is functionalized by the multifarious symbiotic acid–base sites open Pb2+ uncoordinated pyridine groups on inner surface void volume. Gas adsorption tests confirm displays higher separation performance for mixed gases f CO2 CH4 selectivity CO2/CH4 at 273 K 101 kPa being 31 (1:99, v/v), 23 (15:85, 8 (50:50, respectively.

The achievement of photocatalytic CO2 and epoxide cycloaddition under mild conditions such as room temperature atmospheric pressure is important for green chemistry, which can be achieved by developing coordination synergies between catalysts photosensitizers. In this context, we exploit the use coordinate bonds to connect pyridine-appended iridium photosensitizers cycloaddition, systematically demonstrated 1H nuclear magnetic resonance titration X-ray photoelectron spectroscopic measurements. It shown that hybrid Ir(Cltpy)2/Mn2Cd4 system with synergy exhibits excellent catalytic performance (yield ≈ 98.2%), 3.75 times higher than comparative Ir(Cltpy-Ph)2/Mn2Cd4 without 26.2%), conditions. Mn2Cd4 catalyst Ir(Cltpy)2 photosensitizer enhances light absorption photoresponse properties catalyst. This has been confirmed through transient photocurrent, electrochemical impedance, electron paramagnetic tests. Consequently, efficiency was enhanced utilizing
