Summary: In this study, five coordination polymers based on triazole carboxylic acid ligands were synthesized and characterized. The results showed that complexes 1-3 have two-dimensional layered structures, while complexes 4 and 5 have chain structures, and complex 5 further forms a two-dimensional supramolecular structure through hydrogen-bonding interactions. The magnetic properties of complexes 1-4 were investigated and showed antiferromagnetic behavior. Additionally, complex 5 exhibited adsorption performance to Congo red, and detailed studies on adsorption isotherm, kinetics, pH effects, and cycling performance were conducted.

Summary: This study describes two strategies for enantioselective total synthesis of gelsenicine. One approach using chirality transfer cyclization fell short, while a separate asymmetric catalysis route utilizing bisphosphine-gold-catalyzed cyclization was pursued. A catalytic system was identified that provided a synthetic intermediate in high enantiopurity, allowing for the enantioselective formal total synthesis of (+)-gelsenicine.

Summary: Combining chiral ligands with metal ions can create functional spaces similar to those found in biological systems. In this study, silver(I) ions were used to polymerize expanded l-lysine and l-ornithine derivatives, resulting in unique helical structures. The structures of the oligomeric products were determined using DOSY and circular dichroism measurements.

Summary: By doping lanthanides with different binding motifs into coordination polymers, the influence of different fluorine positions in the structure on the decay time of the excited states can be investigated. The CP with a metal-fluorine bond exhibits the highest lifetime of the excited states of lanthanides, enabling the simultaneous excitation of different lanthanides.

Summary: This article discusses the design principles, strategies, and structural outcomes of supramolecular architectures constructed using well-defined coordination complexes as metalloligands. Selected examples of metalloligands with pyridyl or arylcarboxylic acid groups are included to illustrate the construction of supramolecular architectures. The position and number of functional groups appended to a metalloligand were found to critically regulate the resulting material's structural aspects and dimensionality. The article concludes by describing the structure-directing lessons and potential applications of metalloligand-based supramolecular architectures for next-level materials generation.

Summary: Nine heterometallic iodobismuthates with the general formula Cat(2){[Bi2M2I10}] (M = Cu(I), Ag(I), Cat = organic cation) were synthesized. Their crystal structures consisted of {Bi2I10} units interconnected with Cu(I) or Ag(I) atoms through I-bridging ligands, forming one-dimensional polymers. The compounds exhibited good thermal stability below 200 degrees C, and their optical band gaps (E-g) ranged from 1.81 to 2.03 eV. Thermochromism was observed for compounds 1-9, and a linear thermal dependence of E-g was established for all studied compounds.

Summary: Two new Co(II) coordination compounds were synthesized and characterized, one displaying a 2D layered network while the other exhibited a dinuclear structure. Both complexes showed high pH stabilities in the range from 3 to 12, and could serve as fluorescence probes for detecting various substances with high quenching constants and low detection limits. The fluorescence sensing mechanisms of the two compounds were discussed in detail.

Summary: This study reports a new conductive framework of copper halide assembled through halogen bonding and ligand synthesis with aryl thioether. The synthesis method avoids complex organic synthesis and the use of toxic reagents, and it is simple and sustainable. Experimental results show that this new material has a small band gap, strong optical absorption, and a relatively small exciton binding energy, with potential application as a photodetector.
