Thiacalix[4]arene ligands have the advantages of high recognition, derivatization, excellent stability and other advantages. Lanthanide (Ln) ions can coordinate with thiacalix[4]arene ligands to form multi?functional coordination clusters, which received increasing attention due to their unique catalytic, magnetic, optical properties. Thiacalix[4]arene can sensitize Ln ions to luminescence by the coordination of phenol and S groups via the "Antenna effect". This paper reviewed recent advances in structures, luminescent properties, and applications of luminescent Ln?thiacalix[4]arene complexes.

A double polyoxometalates?based composite catalyst material was prepared by Mechanochemistry. In order to compare with the double polyoxometalates?based composite catalyst material, one polyoxometalates?based were prepared by the same method. The structures of these catalysts were characterized by X?ray powder diffraction, Fourier transform infrared spectroscopy, and liquid ultraviolet spectroscopy. The photocatalytic degradation of rhodamine B (RhB) was selected as a model reaction to evaluate its photocatalytic activity and the possible mechanism were further explored in the degradation process. The results indicate that the degradation efficiency of H₃PMo₁₂O₄₀&H₄SiW₁₂O₄₀@MOF?199 is 92% while irradiating in simulated sunlight for 60 minutes, which is superior to that of the corresponding single POMs catalysts H₃PMo₁₂O₄₀ or H₄SiW₁₂O₄₀@MOF?199 and has a good cycling activity. The synergistic effect of the good photocatalytic activity of polyoxotungstates and the good oxidation?reduction ability of polyoxomolybdates, which provides a new vision for designing diverse POMs@MOFs composite catalysts with different catalytic properties.

Electrospinning is a fiber manufacturing process in which polymers are drawn and spun under the action of a high?voltage electrostatic field. This method has been widely used in material chemistry due to the simple preparation, low cost as well as easily available of micro?nano?scale fibers. In this paper, a polysulfur high?nucleus caged compound (Co₄₈) constructed by thiacalixarene was used as the loading material, and polyacrylonitrile (PAN) and polymethyl methacrylate (PMMA) blend (PAN/PMMA) was used as the spinning support, Co₉S₈ nanoparticles loaded carbon nanofibers (Co₉S₈@CNFs) were prepared by electrospinning technique. Composite nanofibers were prepared by spinning carriers with PAN and PMMA mass ratios of 10∶0, 7∶3 and 5∶5, respectively, and the carbon nanofiber composites obtained after heat treatment were used as electrode materials for the study of lithium?ion battery materials. The addition of PAN and PMMA has a positive effect on the electrochemistry of the final product compared to the calcined product of Co₄₈ crystals. The composites fabricated from PAN and PMMA presented high specific capacity，good cycling stability and rate capability.
