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.

Abstract4232)      PDF (411KB)(6839)      

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.

Abstract3889)      PDF (346KB)(6232)      

We monitored the imidization process of poly(amic acid) synthesized from pyromellitic dianhidride and 4,4′-oxydianiline, and analyzed the IR bands of the poly(amic acid) and the polyimide after thermal imidization using variable temperature FTIR spectroscopy in transmission mode. We investigated peak assignments of the poly(amic acid) and the polyimide and found —COO- and —NH+2 in the system. The C=O symmetrical and asymmetrical stretching vibrations in —COO- locate at 1607 and 1406 cm-1 respectively, NH+2 stretching vibration locate at 3200, 3133, 2938, 2880, 2820, 2610 cm-1. According to the identified IR absorption peaks of —COO- and —NH+2, we proposed the mechanism of the imidization process of poly(amic acid) that during the imidization H+ from COOH of the poly(amic acid) can move to NH of the poly(amic acid) and form —COO- and NH+2, then the intermediate cyclodehydrates to polyimide at last.

Compared with single lithium or sodium, lithium-sodium alloy has better performance. In-situ electrochemical preparation of lithium sodium alloy is successfully achieved in button battery which is charged and discharged under gradient current density by using sodium metal as the positive electrode, lithium metal as the negative electrode, and LiPF6, NaClO4 or lithium sodium mixed ion electrolyte as the electrolyte. Benefiting from the synergistic effect of lithium and sodium double electrochemically active ions, the lithium-sodium mixed ion capacitors with different lithium contents as negative electrodes show good electrochemical performance. In particular, with lithium sodium alloy with high lithium content as the negative electrode and NaClO4 electrolyte added, Carbon derived from sodium citrate (Sodium citrate derived carbon, SCDC-activated) maintains the high specific capacity of 238 mA·h/g and the capacity retention rate of 99% at the current density of 1 A/g for 300 cycles. With the addition of lithium-sodium mixed ion electrolyte, SCDC-activated exhibits the specific capacity of 319 mA·h/g, and it can retain 93 mA·h/g and 98% capacity retention rate after 1040 cycles.

Abstract1761)      PDF (1785KB)(4318)      

Chitosan/polyvinyl alcohol/sodium tripolyphosphate complex microparticles were prepared from chitosan, polyvinyl alcohol and sodium tripolyphosphate. The effects of CS content on complex microparticles and different ions, pH on the degree of equilibrium swelling were investigated. The component, structure and morphology of complex microparticles were characterized by means of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM). The results indicate that the chitosan-polyvinyl alcohol is a compatible system; the crystallization of PVA declines with the increase of CS content; the particle size is about 400-950 μm with rough surfaces. The equilibrium swelling tests show that with the increasing of CS content, the equilibrium swelling ratio increases firstly, then decreases; the equilibrium swelling ratio of  CS/PVA/TPP complex microparticles in pH=3-8 solution is the best and in the same solution, that of microparticles decreases with the ion content increases.The microparticles have swelling-shrinking reversibility, implying that CS/PVA/TPP complex microparticles are pH/ion-sensitive and could provide experimental and theoretical basis for drug delivery system.

One linear and one macrocyclic tetrapepitides(4 and 5) with Fmoc were synthesized by two ways of Trt protection group cleavage in the preparation of symmetrical tetrapepitides using cysteine-modified cyclo(L-Lys-L-Lys) diketopi-perazines. Both tetrapepitides show excellent capability to gelate a number of organic solvents to give thermo-reversible organogels. The self-assembled fibrillar networks in the organogels were distinctly observed by SEM. Interestingly, two organogelators could selectively gelate common chlorinated organic solvents from their mixture with water, even at a concentration as low as 0.1%(volume fraction). Moreover, the xerogel obtained from the organogel of compound 4 in chloroform can high efficiently adsorb various tested dyes from aqueous solutions due to the larger specific surface area of 3D xerogel network showing a micro- and nano-sized structure and the π-π interaction between dye molecules and Fmoc protection groups. The absorption capacity of the xerogel for those dyes increases with the temperature.

Synthesis of New Fluorinated Epoxides and Preliminary Investigations on Their UV-curing Properties

Abstract2572)      PDF (384KB)(3974)      

Perfluoroalkyoxy-substituted cyclohexene oxides(EFPO1 and EFPO2) were obtained by two-step reactions using the dimer and trimer of hexafluoropropylene oxide and 4-cyclohexene-1,2-dimethanol as main raw materials. The structures of assynthesized products were confirmed by spectroscopy analyses including FT-IR and 1H NMR. These fluoro-epoxides are compatible with the prepolymers such as bisphenol-A diglycidyl ether and ethylene glycol diglycidyl ether, thereby endowing the coatings composed of them with improved hydrophobicity as evidenced by the photoinitiated curing experiments. The preliminary investigation of their UV-curing performance shows that the hydrophobicity increases linearly with increasing fluoro-epoxide content in the composition. As expected, the hydrophobic effect is more pronounced for EFPO2 than EFPO1 at the same conditions, because the former has a longer ferfluoroalkyoxy group. For example, upon addiing 1% mass fraction of EFPO2, the water contact angle of the UVcured films was 99° and was higher 14° than that found for the films without the fluoro-component, whereas the value for EFPO1modified films was 87°. When containing 5% EFPO2, high hydrophobic surface was achieved with a water contact angle of 113 for the UV-cured films. In addition, it should be pointed out that the hydrophobic surface can be further improved by heating the UVcured films at 110 ℃ for 6 h. For the coatings containing 1%~5% EFPO2, the post-heating treatment resulted in a change of the water contact angles from the range 99°~113° to 113°~118°, while the changes were from 87°~100° to 99°~110° for EFPO1 analogs. The thermal migration of fluorochains and aggregation on the film surface seems to be responsible for the enhancement in hydrophobicity. Consequently, this new type of fluorinecontaining epoxy monomers is expected as the surface modifier used in coatings, inks and release materials.

Inorganic halide perovskite CsPbX3(X=Cl,Br,I) nanocrystals(NCs) have been received much concern because it owns many excellent optical properties, such as high quantum yield(~90%), the emission wavelength covering the entire visible light region(400~700 nm), and the narrow full width at half maximum(12~42 nm). These advantages make it becomes one of the luminescence materials which have the most potential applications. Therefore, in recent years, reports involving inorganic halide perovskite materials become more and more. In this review, the development history, the synthetic routes, structures, growth mechanisms, and applications of inorganic halide perovskite NCs that make them excellent optoelectronic materials for various strategies are mainly discussed and highlighted. The existing problems of inorganic halide perovskite luminescence materials under the current research backgrounds are summarized. Finally, perspectives on future exploration of inorganic halide perovskite NCs for photoelectric devices are also given.

Graphene oxide (GO) and reduced graphene oxide (RGO) were prepared by modified Hummers method and hydrothermal reduction, respectively. They were characterized by transmission electron microscopy (TEM), UV-Vis absorption spectroscopy (UV-Vis), Fourier transform infrared (FTIR) spectroscopy, and photoluminescence emission and excitation spectroscopy(PL, PLE). 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.
