Tetrakis(l,3-dihydrobenzoxazine) calix[4]resorcinarenes 4–6 were synthesized via the Mannich reaction from the corresponding resorcin[4]arenes 1–3 with S-(−)-α-methylbenzylamine or R-(+)-α-methylbenzylamine and formaldehyde (aq.). The products were well characterized by FT-IR, 1H NMR, 13C NMR spectroscopies and single crystal X-ray diffraction analysis. Molecular structures of compounds 4, 5 and 6 showed the same R/S configuration to the starting amines. Compounds 4–6 are stabilized by a collar of intramolecular hydrogen bonding networks between the hydroxy groups and the oxygens from the benzoxazine rings. Compounds 4 and 5 could encapsulate the guest molecules of acetone and dichloromethane, respectively. The UV and 1H NMR titration experiments were performed to study the host-guest chemistry between compound 4 and small acetone molecules, indicating that compound 4 exhibited encapsulation behavior towards acetone molecules through hydrogen bonding interactions.

Nanoporous carbon materials have always presented a special interest due to their properties, which include adsorption (especially of gases), catalyst activity, fluorescence, and luminescence. Their porosity leads to a high surface area, making them suited for assisting processes, such as synthesis (especially carboxylation and electrolytic reduction), catalysis (particularly electrocatalysts and photocatalysis), and separation. Considering these features, carbon nanotubes, graphene oxide, and graphene quantum dots have been extensively investigated for pharmaceutical applications. Coming from either organic, inorganic or synthetic precursors, the nanoporous carbon composites are of great value as adsorbent for the removal of various pollutants. Apart from the removal of pollutants, nanopores serve to separate single stranded and double stranded DNA in solution and rapid DNA sequencing. While the size of the pores depends on the method used for preparation, from a usage standpoint, the nanopores are micropores ((< ! 2 ~ text {nm})), mesopores ((2 !- ! 50 ~text {nm})) and macropores ((> ! 50 ~ text {nm})). The methods of investigation related with nanoporous carbon materials often include X ray diffraction, scanning electron microscopy, fourier transform infrared spectroscopy, transmission electron microscopy, X ray photoelectron spectroscopy, thermogravimetric analysis and X ray powder diffraction. This review summarizes the most recent studies in developing nanoporous carbon materials for various pharmacautical applications including bio-sensing, drug delivery, tissue engineering, biomedicine, gene transfection or cancer therapy. New porous carbon materials, including metal organic frameworks, carbon dots and nanotubes, have been detailed in this review.
纳米多孔碳材料由于其吸附(尤其是气体)、催化剂活性、荧光和发光等特性,一直受到人们的特别关注。它们的孔隙率导致高表面积,使它们适合辅助过程,如合成(特别是羧基化和电解还原),催化(特别是电催化剂和光催化)和分离。考虑到这些特点,碳纳米管、氧化石墨烯和石墨烯量子点在制药应用方面得到了广泛的研究。纳米多孔碳复合材料可由有机、无机或合成前驱体制备而成,在去除各种污染物方面具有重要的吸附剂价值。除了去除污染物外,纳米孔还可以分离溶液中的单链和双链DNA,并快速测序。虽然孔的大小取决于所用的制备方法,但从使用的角度来看,纳米孔是微孔((< ! 2 ~ text {nm}))、中孔((2 !- ! 50 ~text {nm}))和大孔((> ! 50 ~ text {nm}))。与纳米多孔碳材料有关的研究方法通常包括X射线衍射、扫描电子显微镜、傅里叶变换红外光谱、透射电子显微镜、X射线光电子能谱、热重分析和X射线粉末衍射。本文综述了纳米多孔碳材料在生物传感、药物传递、组织工程、生物医学、基因转染和癌症治疗等方面的最新研究进展。本文综述了新型多孔碳材料,包括金属有机骨架、碳点和纳米管。

In biological systems, biomolecules achieve sophisticated functions based on both thermodynamic control and kinetic control. In contrast, in artificial supramolecular systems, molecular recognition behaviors in host–guest systems or self-assembly processes under thermodynamic control have been widely investigated for several decades. Recently, kinetic control of these processes has attracted more interest. This review describes three approaches for the kinetic control of supramolecular systems based on coordination chemistry. The discussion first focuses on the kinetic control of guest uptake of host–guest systems. The guest binding kinetics (i.e., guest uptake/release rate) can be basically controlled by the change in the aperture sizes of the host molecules. The second part provides representative examples of unveiling guest uptake/exchange mechanisms for a variety of supramolecular host–guest systems, which is important for the rational design of host molecules and prediction of their specific functions for future studies. The kinetic control of metal-assisted self-assembly processes is also introduced in the last part. The discussion especially focuses on investigation of the self-assembly pathway, control of the kinetic stability of self-assembled complexes, and the speed tuning of self-assembly processes by modulating the individual metal–ligand exchange rate.

The monitoring of shifting of the redox potential of macrocyclic complexes towards anodic or cathodic regions, which acts as a mediator in many electrocatalytic events, is made possible by inserting electron donating or electron withdrawing group into their frameworks. Herein, using a template strategy, two [14]-membered N4-macrocyclic complexes (denoted as complex A and complex B) with similar molecular cores but different phenyl moieties were prepared and characterized using multiple characterization techniques. The characterization results suggested a saddle-shaped geometry for these complexes, which might be due to the steric repulsions between the benzenoid and amidic moieties on the macrocyclic framework, as also supported by theoretical computations. Further, to investigate the electrochemical behaviors of these complexes, cyclic voltammetry was used and found that the Fe3+/2+ redox potential was systematically shifted in anodic direction with the increment of phenyl moieties on the [14]-membered N4-macrocyclic core. DFT calculations indicated the down-shifting in the most occupied molecular orbital due to the increased phenyl conjugation, which could be correlated with the shifting of Fe3+/2+ redox potential. Biological evaluation of these complexes has also been carried out.

Purpose
Due to the mentionable importance of macrocyclic compounds different metal complexes with a new macrocyclic ligand have been prepared in this study. To materialize this expectation, a new N-pendent derivative LAZ was prepared by the interaction between isomeric ligand, LA (a C-chiral isomer of 3,10-C-meso-Me8[14]ane) and CH3I at 1:4 ratio under reflux in methanolic solution. LAZ underwent complexation with Ni(II), Cu(II) and Zn(II) salts to form four coordinated square planar orange [NiLAZ](ClO4)2 square planar violet [CuLAZ](ClO4)2, and five coordinated square pyramidal white [ZnLAZ(NO3)](NO3) complexes respectively. The axial addition reactions on [CuLAZ](ClO4)2 with NCS−, NO3−, NO2−, Cl−, Br− and I− afforded different colored six coordinated octahedral axial addition products: purple [CuLAZ(NCS)2]; pink [CuLAZ(NO3)(ClO4)]; pink [CuLAZ(NO2)(ClO4)]; pink [CuLAZCl(ClO4)]; pink [CuLAZBr2] and deep blue [CuLAZI(ClO4)] respectively.
Methods
The compounds were characterized on the basis of different analytical parameters. Antibacterial and antifungal activities of newly prepared compounds were investigated by using standard methods.
Results
The metal complexes of LAZ showed different geometries with required coordination. Theses complexes also showed electrolytic behavior in different solvents. The ligand LAZ and its metal complexes exhibit moderate antimicrobial activities toward different phytopathogenic bacteria and fungi.
目的由于大环化合物的重要性,本研究制备了不同的金属配合物与新的大环配体。为了实现这一期望,在甲醇溶液回流条件下,将异构体LA (3,10- c -meso- me8[14]烷的c -手性异构体)与CH3I以1:4的比例相互作用制备了新的n -依赖性衍生物LAZ。LAZ分别与Ni(II)、Cu(II)和Zn(II)盐络合形成4个配位方形平面橙色[NiLAZ](ClO4)2方形平面紫色[CuLAZ](ClO4)2和5个配位方形锥形白色[ZnLAZ(NO3)](NO3)配合物。在[CuLAZ](ClO4)2上与NCS−、NO3−、NO2−、Cl−、Br−和I−进行轴向加成反应,得到不同颜色的六配位八面体轴向加成产物:紫色[CuLAZ(NCS)2];粉色(CuLAZ(3号)(ClO4)];粉色(CuLAZ (NO2) (ClO4)];粉色(CuLAZCl (ClO4)];粉色[CuLAZBr2]和深蓝色[CuLAZI(ClO4)]。方法采用不同的分析参数对化合物进行表征。采用标准方法考察了新制备化合物的抑菌活性和抗真菌活性。结果LAZ金属配合物具有不同的几何形状和配位要求。这些配合物在不同溶剂中也表现出电解行为。配体LAZ及其金属配合物对不同的植物病原菌和真菌表现出适度的抑菌活性。

A novel derivatives of tetraazacalix[4]arene[2]triazine-based catalysts for enantioselective Michael addition reactions of nitroolefins and diketones were presented. Chiral moieties were connected to the heteroatom-bridged calix-triazin scaffold by reactions of (S)- or (R)-(+)-1-(1-Naphthyl)ethylamine with tetraazacalix[4]arene[2]triazine. To utilize the catalytic activity of the chiral catalysts, diketones reacted with a wide variety of trans-β-nitrostyrenes in Toluene, respectively, obtaining the Michael products in excellent yields and enantiomeric excesses (up to 96% yield and 99% ee).
