Under hydro(solvo)thermal conditions, two 4-(4-carboxyphenoxy)phthalate-based three-dimensional (3-D) coordination polymers: [Cd3(cpph)2(bpa)2(H2O)]·0.5H2O (cpph = 4-(4-carboxyphenoxy)phthalate, bpa = 1,2-bis(4-pyridyl)ethane) 1, and [H2(bpp)][Mn2(cpph)2(H2O)2] (bpp = 1,2-bis(4-piperidyl)propane) 2 were isolated. In both compounds, the cpph molecules extend the metal ions into a 3-D network: a (4,6)-connected net for 1 and a simple 6-connected net with a pcu topology for 2. The introduced bpa or bpp molecule stabilizes the 3-D metal-cpph architecture in the form of linker or guest molecule. The sensing ability of 1 was investigated, revealing that it can be used as a fluorescence probe to sense nitrobenzene at ppm concentrations.

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.

As a new generation of high-energy-density energy storage system, solid-state aluminum-ion batteries have attracted much attention. Nowadays polyethylene oxide (PEO)-based electrolytes have been initially applied to Lithium-ion batteries due to their flexible processing and good interfacial compatibility, their application in aluminum-ion batteries still faces problems. To overcome the limitations in aluminum-ion batteries-specifically, strong Al coordination suppressing ion dissociation, high room-temperature crystallinity, and inadequate mechanical strength-this study develops a blended polymer electrolyte (BPE) of polypropylene carbonate (PPC) and PEO.
