Abstract
Coordination polymers (CPs) have recently emerged as promising candidates for heterogeneous photocatalysis due to their structural designability and tunable properties. Herein, we developed two novel Ag(I)-calix[4]arene coordination polymers with the formula {[Ag2(μ-NO3)L1]}n (CP 1) and {[AgL1]·PF6}n (CP 2) (L1 = 2-mercapto-5-methyl-1,3,4-thiadiazole resorcinol calix[4]arene). Crystallography revealed that anion coordination and self-inclusion behavior induced the cavitand and silver ions to self-assemble into well-defined CPs 1 and 2 with different topological coordination frameworks, respectively. Furthermore, CPs 1 and 2 display high photocatalytic activity for the photodegradation of rhodamine B (RhB) and methyl orange (MO) in an aqueous solution under mild conditions (WLED and UV irradiation). The comparison results demonstrate that CP 1 exhibited better photocatalytic performance than CP 2, which correlated well with the differences in their molecular structure and HOMO-LUMO energy gaps. The photocatalysis products and possible intermediates were successfully monitored and determined using mass spectrum, gas chromatography, and electron paramagnetic resonance measurements. The rational photocatalysis mechanism was further investigated and proposed.

Structural and Antimicrobial Characterization of Co-Crystal [Ni(bpy)(acr)2(H2O)]·MA. CRYSTALS 2022. [DOI: 10.3390/cryst12081078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
A new co-crystal with the formula [Ni(bpy)(acr)2(H2O)]·MA (bpy = 2,2′-bipyridine, acr = acrylate and MA = melamine) has been synthesized and characterized using IR, UV-Vis, thermogravimetric analysis and single crystal X-ray diffraction. The complex contains discrete unities of [Ni(bpy)(acr)2(H2O)] and melamine linked in a complex network by both hydrogen bonds and π-π stacking interactions. Structural characterization revealed that Ni(II) adopts an octahedral distorted stereochemistry, and acrylate ions present both unidentate and chelate coordination modes. Thermal decomposition occurs in four steps, the ligands being stepwise released in the order of water, acrylate, bipyridine and melamine. The antimicrobial activity of the obtained complex, its precursor ([Ni(bpy)(acr)2(H2O)]) and melamine were assessed against planktonic (minimal inhibitory concentration—MIC) and biofilm-embedded (minimal biofilm eradication concentration—MBEC) Gram-positive and Gram-negative bacterial strains. The obtained results revealed that the new complex and its precursor exhibited a superior activity compared to MA, the highest susceptibility being recorded for the Staphylococcus aureus strain. The MIC and MBEC ranges were very similar, indicating the potential of this complex and its precursor to develop novel anti-biofilm agents.

Abstract
Two new supramolecular frameworks, namely [Zn(HBTC)(H2O)2]n·n(MA) (1) and {[Cd(OBDC)2(MA)(H2O)Cl](HMA)3(H2O)10(DMA)}n (2) (H3BTC = 1,3,5-benzenetricarboxylic acid, H2OBDC = phthalic acid, MA = melamine, DMA = N,N'-dimethylacetamide), have been solvothermally prepared. In addition, the solid-state luminescent properties of 1-2 at room temperature was discussed in this article as well. Their application values on the cardiovascular disease treatment were explored and we also discussed the corresponding mechanism simultaneously. Firstly, the IL-6 and IL-18 released into the plasma was measured with indicated ELISA assay. Besides, the real time RT-PCR was also performed, while activation levels of AMPK signaling pathway was determined after compound treatment.

Abstract
A new binuclear copper(ii) Schiff base complex [Cu2 L2− (NO3)2]·2CH3OH (1) [L = 2,6-bis((E)-(p-tolylimino)methyl)-4-methoxyphenol] was synthesized using a template method in which the tridentate N2O Schiff base ligand was derived from [1 + 2] condensation of 2,6-diformyl-4-methoxyphenol and p-methyl aniline in the presence of copper(ii) ions as the template agent. The X-ray diffraction analyses revealed that this complex crystallizes in the monoclinic system with space group P21/n. The most remarkable structural feature of 1 is that it contains two types of 1D right-handed helical chains. The molecules are linked by intermolecular hydrogen bonds and π⋯π interactions, then a 3D supramolecular network was constructed. Moreover, the intermolecular interactions on the crystal packing of 1 have been further studied using Hirshfeld surface analysis and corresponding 2D fingerprint plots. Binding interaction of this complex with calf thymus DNA (CT-DNA) has been investigated using absorption and emission studies, viscosity experiments and circular dichroism studies. Complex 1 shows significant binding to the DNA. The results of fluorescence spectroscopy and UV absorption spectroscopy, CD spectroscopy and viscosity indicated that this complex interacted with CT-DNA in a groove binding mode where the binding constant was 1.3 ± 0.2 × 104 L mol−1. Our fluorimeteric study showed that the reaction between 1 and CT-DNA was exothermic (ΔH = 59.6 kJ mol−1; ΔS = 268.79 J mol−1 K−1). Antibacterial activities of the complex were screened by the disc diffusion method against three Gram-positive bacteria (Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 23212 and S. epidermidis ATCC 34384), and three Gram-negative bacteria (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853 and Klebsiella pneumonia ATCC 70063). The results indicated that this complex demonstrated acceptable antibacterial activities. A new binuclear copper(ii) Schiff base complex was synthesized using a template method in which the tridentate N2O Schiff base ligand was derived from [1 + 2] condensation of 2,6-diformyl-4-methoxyphenol and p-methyl aniline.![]()

Abstract
Achieving reversible molecular crystal transformation between coordinate aggregates and hydrogen bonded assemblies has been a challenging task because coordinate bonds are generally much stronger than hydrogen bonds. Recently, we have reported the incorporation of silver ions into the cyanuric acid-melamine (CAM) network, resulting in the formation of a 1D coordination polymer (crystal 1) through forming the κ1N-Ag-κ2N coordination bonds. In this work, we find crystal 1 will undergo reversible transformation to hydrogen bonded coordinate units (crystal 2) through the breaking of coordinate chains and then the addition of CAM hydrogen bonding motifs into the framework. Crystal 2 presents a pseudohexagonal arrangement comprised of the κ1N-Ag-κ2N units connected by two sets of the triple hydrogen bonds, which extends two-dimensionally and stacks into a layer-structured crystal. Light was shed on the tautomerization of CA and M ligands associated with the crystal transformations using single crystal X-ray diffraction and infrared spectroscopy by analyzing the bond lengths and vibrations. We also highlight that photoluminescence can be a useful tool to probe the tautomer conversions of conjugated molecules. Furthermore, crystal 1 demonstrates high flexibility and can be bent over 180° and recover to its original shape after stress release. Crystal 2, on the contrary, is brittle and shows distinct mechanical anisotropy along different crystal orientations, as unveiled by nanoindentation measurements. The elastic modulus is well correlated with the chemical bonding strength along each orientation, and it is noteworthy that the contribution of the triple hydrogen bonds is comparable to that of the coordination bonds.
