Metal-organic frameworks(MOFs) are a new class of hybrid porous crystalline materials constructed from metal-oxygen clusters with organic linkers, creating three dimensional ordered frameworks. As porous materials, MOFs usually possess very high surface area. The framework topologies and pore size of MOFs can be designed via choosing various metal centers and organic linkers, their chemical properties can be modified by chemical functionalization of linkers and post modification. These unique characteristics make MOFs one of the research hot spots in the fields of chemistry and materials, and they have shown potential applications in various research areas. But there is a crucial weakness which hinders the development of MOFs, namely, the low stability. However, zirconium-terephthalate-based MOF UiO-66 has remarkable hydrothermal stability, the framework is claimed to be stable up to 500 ℃, and it is also highly resistant to many solvents. UiO-66 has gained great attention since the outstanding qualities. In this review, details of the synthesis modulation and functionalization of UiO-66 are presented. In addition, the research actuality and prospective of UiO-66 in the fields of adsorption, catalysis, etc. are also discussed.

Abstract4374)      PDF (336KB)(1510)      

The abilities of sodium alkyl aryl sulfonate, which had highpurity and defined structure, to emulsify alkanes, were investigated by a water diversion method. Using liquid paraffin wax as the oil phase, the effects of the concentration of emulsion, length of alkyl chain, structures and locations of aryl groups in alkyl chain on emulsion stability were studied, and the best concentration of emulsion were determined. Meanwhile, the effects of different oil phases to emulsion stability were discussed. The experimental data showed that the best mass fraction of emulsion was 0.1%. With definite structures of aryl group, emulsion stability increased linearly with the increasing of the length of carbonic chain. When the length of alkyl chain on alkyl group was set, the emulsion stability was enhanced with the increasing of the length of alkyl chain on aryl group. With the aromatic ring shifts from the terminal to the center of the long alkyl chain, the emulsion stability increased. With the increase of molecular mass of oil phases, the molecular mass of emulsifier to achieve stable emulsifying liquid increased.

Abstract4227)      PDF (359KB)(1487)      

Six different imidazoline quaternary ammonium salts were synthesized with the use of valeric acid, decanoic acid, oleic acid, diethylenetriamine, benzyl chloride and thiourea as raw materials. The corrosion inhibition performances of quaternary ammonium salts of thioureido alkyl imidazoline and alkyl imidazoline on carbon steel in 1.0 mol/L HCl medium were compared at 80 ℃ via both static mass loss and polarization curve methods. The synergies between each of these two corrosion inhibitors and each of the inorganic anions or anionic surfactants were also investigated. The results show that the inhibition effect of quaternary ammonium salt of thioureido alkyl imidazoline reaches a 98.3% rate of corrosion inhibition and is significantly superior to that of quaternary ammonium salt of alkyl imidazoline. The best corrosion inhibition effect is achieved when the mass ratio of quaternary ammonium salt of thioureido alkyl imidazoline to I- is 1∶1 during preparation process. This gives a corrosion inhibition effect 1.5% higher than that of quaternary ammonium salt of thioureido alkyl imidazoline compounds used alone.

Abstract4153)      PDF (411KB)(6806)      

A novel conjugated polymer containing azobenzene and 1,3,4-oxadiazole units(LPOXD) was synthesized. The structure of the LPOXD was charactered by FT-IR, UV-Vis, 1H NMR, GPC, TGA and DSC. The results indicate that the intrinsic viscosity of the LPOXD is 0.02960 L/g, and its Mw and molecular mass distribution or polydispersity index(PDI) values are 8500 g/mol and 1.55, respectively. A 5% mass loss of the LPOXD occurred at 290 ℃. The glass-transition temperature(Tg) is 92.8 ℃. The introduction of long side chain of alkoxy significantly improved LPOXD′s solubility in common organic solvents such as chloroform, tetrahydrofuran, and so on. Furthermore, the optical and electrochemical properties of the LPOXD were investigated throughly by UV-Vis absorption spectroscopy, fluorescence emission spectroscopy and cyclic voltammetry. The results indicate that the azobenzene in the LPOXD involve a trans-cis photoisomerization under the radiation of 365 nm UV light. A wide fluorescence peak of the LPOXD appeared in the wavelength range of blue and purple light under excitaion at 350 nm. Cyclic voltammetry reveals that the LUMO and HOMO energies of the LPOXD are -5.96 eV and -3.17 eV, respectively.

2,6-Di(2′-imidazoline-2′-yl)pyridine, even though it is not fully aromatic, has the same distribution of heteroatoms as 2,6-di(2′-benzimidazol-2′-yl)pyridine and has been synthesized from pyridine 2,6-dicarboxylic acid and ethylenediamine under microwave irradiation and without catalyst. The composition and structure of the product were identified and characterized by IR, mass spectrometry, 1H NMR, 13C NMR and melting point determination. The ratio of products and byproduct was found to be different under different experimental conditions(solvents, proportion of reacting mass, power of microwave irradiation). Among them, solvents have very obvious effects on the ratio of product and byproduct. The experimental results indicate that the best solvent is ethylene glycol. The optimal reaction condition are follows:molar ratio of raw materials 1∶2.7, microwave power 450 W, irradiation time 65 min, irradiation temperature 130 ℃ and the overall yield 71.2%. The binding of this compound with calf thymus DNA was investigated by UV and viscosity measurements. The binding constant Kb is meaused to be (9.60±0.05)×104 L/mol, which is lower than those observed for typical classical intercalators. The results of viscosity measurement reveal that the presence of 2,6-di(2′-imidazoline-2′-yl)pyridine has no obvious effect on the relative viscosity of DNA. It may bind to DNA by hydrogen bonding and grooveface binding.

Nanozymes are a kind of nanomaterials with enzyme-like activity. Since they were first discovered in 2007, nearly a thousand kinds of nanomaterials with different compositions have been found to have enzyme-like activity. They exhibit similar enzymatic reaction kinetics and catalytic mechanisms to natural enzymes and can be used as a good substitute for natural enzymes. Due to the enzyme-like activity and the advantages of multifunctionality, economy, stability, and easy to scale production, nanozymes have shown good application prospects in the rapid detection of pathogenic microorganisms and the prevention or treatment of infectious diseases. Therefore, nanozymes are regarded as a new type of biosafety material. This article reviews the application of nanozymes in detecting and killing of bacteria and viruses in recent years, and provides a basis for the development of diagnostic and anti-pathogenic microbial treatment strategies based on nanozyme when responding to major biosafety threats and preventing biosafety hazards.

PL spectra indicate that the broad near-infrared(NIR) photoluminescence ranging from 600 to 800 nm can be acquired from graphene oxide under excitation of visible light. By comparing PL spectra from GO with that from RGO, and through the analysis of their UV-Vis absorption and FTIR spectra, the oxygen related groups, such as C=O and COOH, are found to be responsible for the NIR PL from GO. NIR fluorescence is favorable for bio-imaging because of its excellent penetrating ability and little damage to tissues. This indictates that GO has great potential applications in bio-imaging.

Five kinds of 4,6-diaryl-2-aminopyrimidine derivatives were synthesized and characterized by IR, MS and 1H NMR. The Escherichia coli methionine aminopeptidase(EcMetAP) inhibitactivities and the CXCR4 receptor antogonists activities of the five compounds were determined. The results show that all the five compounds have the EcMetAP inhibit-activities, and they also have CXCR4 receptor antogonists activities except the compound 2. The structure-activity relationships were studied by the FieldTemplater and FieldAlign software through molecular field analysis. The results show that the pharmacophore could be 3-N atom and 4,6-bencycles used as the EcMetAP inhibitor,and the EcMetAP inhibit-activities could be increased by addition of electron-donating groups at 6-benzyl. It also shows that the pharmacophore could be 2-C atom and 4,6-bencycles used as the CXCR4 receptor antogonists. The CXCR4 receptor antogonists could be increased by addition of electrondonating substituent at 2-C.

Two pyridyl imidazo[4,5-f]1,10-phenanthroline derivates, namely 2-(3-pyridyl)-imidazo[4,5-f]1,10-phenanthroline(G1) and 2-(4-pyridyl)imidazo [4,5-f]1,10-phenanthroline(G2), were synthesized and characterized by elemental analysis, 1H NMR and MS. Under various concentrations of cucurbit[n]urils(Q[n], n=6,7), the interaction of Q[n] with G1 and G2 were studied in buffer solutions with different pH values by using UV-Vis spectroscopy and fluorescence spectrophotometry. The results revealed that cucurbit[n]urils(n=6,7) form a 1∶1 complex with G1, and Q[6] form a 1∶1 complex with G2 in acidic solution, fluorescent sensitizing effects of both Q[6] and Q[7] toward guests were determined. Under acidic solution Q[7] formed a 2∶1 complex with G2, and a fluorescent quenching effect of Q[7] on G2 was observed. Association constants(K) of Q[n](n=6,7) with G1 were found to be 3.00×104 L/mol, 1.86×104 L/mol respectively, while those of Q[n](n=6,7) with G2 are 1.64×104 L/mol and 1.01×103 L/mol respectively. With decreasing acidity of the systems, the interaction between guests and Q[n](n=6,7) weakened and no interaction was observed under neutral conditions.

In order to provide a reference for octenyl succinic anhydride(OSA)-modified starch and methyl oleate used in green pesticide preparations, the formulation of the lambda-cyhalothrin oil-in-water emulsion with OSA-modified starch and methyl oleate as emulsifier and solvent was studied. Furthermore, the effects of different processing parameters, including the concentration of pretreating fluid of OSA-modified starch, rotational speed and shearing time on the stability of emulsion were studied by measuring oil droplet diameter distribution. Results demonstrated that OSA-modified starch had excellent emulsification ability to methyl oleate. High stable emulsions(2.5%) could be prepared with OSA-modified starch. The mean droplet diameters of emulsion were about 1.2 μm, and increased by only 0.1~0.3 μm after storing at 25 ℃ for 6 months or at (54±2) ℃ for 14 days, and approximately 100% of the oil remained stable in the emulsion. Higher stable emulsions could be prepared by emulsification at high viscosity with mass fraction of pretreating fluid of OSA-modified starch in the range of 15%~25%. Smaller oil droplet diameters were obtained when the rotational speed was increased, which had no significant effect on homogeneity of emulsions. On the other hand, an increase of the shearing time reduced the span of oil droplet diameter distribution, but had no significant impact on the mean oil droplet diameter. Lambda-cyhalothrin oil-in-water emulsion prepared with OSA-modified starch had a better stability than the conventional emulsions. The results of this study show that OSA-modified starch and methyl oleate can be used as an effective emulsifier and solvent for the environment-friendly lambda-cyhalothrin oil-in-water emulsion formulations.
