Article Abstract
Rational design of heterogeneous acid catalysts possessing uniform dispersion of active sites plays a significant role in the catalytic performance. In the present work, a coordination polymer, [Zn(4,4'-bpy)(μ-Hbtc)(HO)] ⋅ 2HO (Zn-CP), was solvothermally synthesized using 4,4'-bpy (=4,4'-bipyridine) and Hbtc (=1,3,5-benzenetricarboxylic acid) mixed linkers. Single crystal X-ray analysis of the polymer displayed that Zn-CP chains were decorated with 4,4'-bpy having unidentate coordination fashion. Then, the free N atom of the linker in Zn-CP was functionalized by -SOH groups to afford Zn-CP-SOH with enhanced acidity. The structures were characterized by FT-IR, thermogravimetric analysis, powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), temperature programmed desorption of NH (NH-TPD), and field emission scanning electron microscopy (FE-SEM) analyses. The coordination polymer was employed as a heterogeneous catalyst for the alcoholysis of epoxides under room conditions. Zn-CP-SOH exhibited excellent catalytic activity and regioselectivity in the methanolysis of styrene oxide within short reaction time.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

Coordination polymers (CPs) are versatile materials formed by metal ions and organic ligands, offering a broad range of structural and functional possibilities. Phosphonates and phosphinates are particularly attractive ligands for CPs due to their multiple binding sites, varied coordination geometries, and ability to form robust network structures. Phosphonates, considered harder ligands, form strong bonds with hard metals such as Fe, while phosphinates offer additional versatility due to the varied pendant groups on phosphorus.

In the context of the importance of manganese β-diketonates as precursors for the preparation of manganese oxide thin films and nanostructured materials, we report synthetic protocols and pitfalls encountered in the preparation of a family of Mn(ii) complexes of two fluorinated β-diketonates, 1,1,1-trifluoroacetylacetonato- (tfac) and 1,1,1,5,5,5-hexafluoroacetylacetonato- (hfac). The synthetic conditions and crystal structures of six new complexes are reported, including a coordination polymer {K[Mn(tfac)]}, an unusual trinuclear complex Mn(tfac)(OH), and a series of mononuclear complexes with coordinated solvents tetrahydrofuran, 1,2-dimethoxyethane, water, and acetonitrile. The crystal structures of two known Mn(ii) complexes are also reported for completeness.

Dynamic micro/nano-structured surfaces play pivotal roles in biological systems and engineering applications. Despite considerable progress has been made in fabricating precisely ordered architectures, achieving controlled motion in top-down fabricated structures remain a formidable challenge. Here, we introduce an advanced dynamic micron-nano optical platform featuring hierarchical microscale wrinkles integrated with ordered nanoscale arrays.

[Cu(3-bph)(PABA)(HO)] () (3-bph = ,'-bis(3-pyridylmethylene)hydrazine and PABA = -amino benzoate) is a pyridyl-N bridging Cu coordination polymer, and PABA acts as a carboxylate-O donor forming a square pyramidal CuNO motif following a zigzag one-dimensional (1D) lattice. The shows weak antiferromagnetic coupling ( = -0.196(1) cm), and emission appears at 352 nm (λ = 293 nm), which is selectively quenched by Fe via the FRET mechanism.
