Treatment of ArNHCH₂CH₂OH (HL, Ar＝2,6-Me₂C₆H₃) with AlMe₃ and ZnEt₂ resulted in the formation of a bi-aluminum complex, [(Me₂Al)(L)]₂ (1), and a tetra-zinc complex, [EtZn₂(L)₃]₂ (2), respectively. They were characterized by elemental analysis, NMR, and single-crystal X-ray diffraction analysis. Complex 1 is a crystallographically centrosymmetric dimer with an Al₂O₂ core in the solid state, while a Zn₄O₆ core is observed in 2, which can be viewed as two side-by-side cubes missing a pair of opposite vertices. Preliminary catalytic activity tests indicated that the aluminum complex 1 was inactive for the ring-opening polymerization (ROP) of ε-caprolactone, while the zinc complex 2 was a highly active initiator for the ROP of ε-caprolactone and could control the molecular weight distribution of the resulted polymers in narrow ranges.

A cobalt-based metal-organic framework [Co₃(L)₂(1, 4-bib)₄]·4H₂O (Co-MOF) was prepared using 5-[(4-carboxyphenoxy)methyl]isophthalic acid (H₃L) and 1, 4-bis(1H-imidazol-1-yl)benzene (1, 4-bib) as ligands. Then, an electrochemical sensor modified with Co-MOF on a glassy carbon electrode (Co-MOF@GCE) was constructed for detecting Cd²⁺ and Pb²⁺ in aqueous solutions. The sensor exhibited a linear range of 1.0-16.0 μmol·L^-1 with a detection limit (LOD) of 4.609 nmol·L^-1 for Cd²⁺, and 0.5-10.0 μmol·L^-1 with an LOD of 1.307 nmol·L^-1 for Pb²⁺. Simultaneous detection of both ions within 0.5-7.0 μmol·L^-1 achieved LOD values of 0.47 nmol·L^-1 (Cd²⁺) and 0.008 nmol·L^-1 (Pb²⁺), respectively. Analysis of real water samples (tap water, mineral water, and river water) yielded recoveries of 95%-105%, validating practical applicability. Density functional theory (DFT) calculations reveal that synergistic interactions between cobalt centers and N/O atoms enhance adsorption and electron-transfer efficiency. CCDC: 2160744.

使用不同金属盐(高氯酸锌、高氯酸镍)与配体2，7-萘二羧酸(H₂NDA)、1，4-二(1H-咪唑-1-基)苯(1，4-DMB)反应，在溶剂热条件下成功构筑出2例具有不同性质的配位聚合物：{[Zn(NDA)(1，4-DMB)_0.5(H₂O)]}_n (Zn-CP)和{[Ni(NDA)(1，4-DMB)(H₂O)₃]}_n (Ni-CP)，并采取单晶X射线衍射、Hirshfeld表面分析、热重分析等手段进一步探究二者的结构、晶体内相互作用、相纯度及热稳定性。研究结果表明：2个配位聚合物均为一维链状结构，并最终都通过丰富的分子间氢键和π…π堆积相互作用形成了3D超分子结构。值得注意的是，2个配合物合成时，除金属阳离子不同外，阴离子及其余试剂和条件方法均相同，但在Zn-CP中Zn²⁺处于四配位的变形四面体中心，NDA^2-配体中的羧基均参与配位，为一双齿桥联配体，配位聚合物最终结构为一维梯子形链；而Ni-CP中，Ni²⁺处于六配位的变形八面体中心，但NDA^2-配体中只有一个羧基参与配位，为一单齿端基配体，因此配位聚合物仅为一维扭曲梯形链。此外，固体荧光和电催化硝酸根还原制氨性能测试结果显示，Zn-CP具有较好的荧光性质，而Ni-CP具备一定的电催化硝酸根还原制氨能力。

To overcome the limitations of traditional photocatalysts, such as inefficient separation of charge carriers and poor visible-light absorption, S-scheme g-C₃N₄/TiO₂ heterojunction photocatalysts were synthesized via a combined method of thermal polymerization, hydrothermal synthesis, and calcination. The crystal structures, morphological features, and optical properties of the composites were systematically characterized, and their photocatalytic performance was evaluated through tetracycline (TC) degradation and hydrogen evolution experiments. Trapping experiments and electron paramagnetic resonance (EPR) measurements were conducted to elucidate the reaction mechanisms. The results demonstrate that the S-scheme heterojunction effectively extends the visible-light absorption range and facilitates the efficient separation of photogenerated electron-hole pairs. Under optimal conditions, the composite achieved a TC degradation rate of 94.5% and a hydrogen evolution rate of 329.1 μmol·h^-1·g^-1 after 8 h of irradiation, both values being significantly higher than those of pristine g-C₃N₄ or TiO₂. Moreover, the S-scheme g-C₃N₄/TiO₂ heterojunction retained high photocatalytic activity over five consecutive cycles, confirming its excellent stability. Mechanistic investigations revealed that the S-scheme heterojunction maintained strong redox capacities, with superoxide radicals (·O₂^-), hydroxyl radicals (·OH), electrons (e^-), and holes (h⁺) serving as the primary active species responsible for TC degradation and H₂ production.
