Abstract
Presented here is a new Zn(II) coordination polymer, namely [Zn2(L)2(bpe)]n (1, H2L = 4-({2-[(4-carboxyphenoxy)methyl]phenyl}methoxy)benzoic acid, bpe = 1,2-bis(4-pyridinyl)ethane), which has been hydrothermally synthesized via the mixed-ligand strategy. Moreover, compound 1 emits intense luminescence at room temperature, and can be used as a luminescent sensor for the detection of Fe3+ in water solution with high selectivity and sensitivity. As representatives of natural polysaccharides, hyaluronic acid (HA) and carboxymethyl chitosan (CMCS) have good biocompatibility. A new type of HA/CMCS gel particles loaded with Paclitaxel drug metal-organic framework was prepared by chemical synthesis method and its micromorphology was studied. Finally, biological experiments were conducted to evaluate the new system's effect on the activity of human lung cancer cells.

Abstract
Abstract
A two-dimensional Ni(II) coordination polymer (NiCP) of the formula {[NiL(terephthalate)(H2O)2]·2H2O}
n
(L = bis(1-(pyridin-4-ylmethyl)-benzimidazol-2-ylmethyl)ether), has been obtained from a solvothermal reaction, and characterized by single-crystal X-ray diffraction, elemental analysis, and IR and UV/Vis spectra. The coordinated terephthalate anions and the L ligands connect the Ni(II) ions in two directions, resulting in the construction of a corrugated layered structure. The electrochemical properties of a NiCP-CPE composite electrode supported by this coordination polymer were studied. For the electrocatalytic hydrogen evolution reaction, the required overpotential of this electrode (NiCP-CPE) is −521 mV when the current density reaches 10 mA cm−2. Compared with the solid carbon paste electrode (sCPE, −976 mV), the smaller overpotential proves effective electrocatalysis of the coordination polymer of the hydrogen evolution reaction. The doped electrode also exhibits high-efficiency in the electrochemical sensing of l-ascorbic acid in water, showing a detection limit of 0.28 μM in a linear range of 0.4–4000 μM.
