Rational design and preparation of transitional-metal-oxide-based battery-type materials possessing comprehensive merits for supercapacitors have attracted extensive attention due to the high theoretical specific capacity energy density. Herein, we demonstrate general fabrication ultrathin-nanosheet-structured transitional-metal oxides on Ni foam via a facile hydrothermal synthesis with assistance formamide. Using poly(vinyl pyrrolidone) (PVP) as directing agent, can generate ultrathin Co3O4...
We designed and synthesised a reactive mesogen (CRM) containing cinnamate moiety in the core two acrylate groups at both ends. The structure was characterised by 1H NMR FT-IR, its liquid crystalline property investigated DSC POM. compound showed nematic phase between 175.2 – 97.5 oC, followed smectic C 57.9 oC during cooling cycle. proposed fabrication method to achieve uniaxial homogeneous alignment of crystals irradiating CRM-doped LC mixture sandwich cell in-plane switching mode (CRM-IPS)...
A polymer-stabilized vertical alignment (PS-VA) mode using a new type of photoreactive monomer for polymer stabilization the liquid crystal (LC) director was developed. Conventional reactive mesogens having higher molecular weight than those host LC tend to aggregate and form large-sized grains when exposed ultraviolet (UV) light, subsequently deteriorating quality dark state. To address these problems, bis(4-hydroxyphenyl) diacrylates were synthesized with four different linking groups as...
Novel photocrosslinkable sulfonated poly(arylene ether sulfone)s containing chalcone moieties in the polymer backbone (SPAEF) were synthesized from 4,4′-dihydroxychalcone (4DHC), 4,4′-difluoro-diphenylsulfone-3,3′-disulfonate (SDFDPS) and decafluorobiphenyl (DFBP). We introduced a new strategy to crosslink photosensitive electrolyte membranes by UV irradiation swollen state order preserve interconnected hydrophilic channels hydrated SPAEF membrane. Photocrosslinked showed desired effects of...
The <sc>l</sc>-<i>tert</i>-leucine-derived AmidPhos/silver(I) catalytic system has been developed for the asymmetric [3+2] cycloaddition of azomethine ylides with electronic-deficient alkenes or without Et<sub>3</sub>N. Under optimal conditions, highly functionalized <i>endo</i>-4-pyrrolidines were obtained modest to high yields (up 99% yield) and enantioselectivities 98% ee).
Abstract Novel sulfonated poly(arylene ether ketone)s (SCKs) containing photosensitive chalcone units in the main chain are synthesized by polycondensation of 4,4′‐dihydroxylchalcone, perfluorobiphenyl, and sodium 5,5′‐carbonyl bis(2‐fluorobenzenesulfonate). Photocrosslinking SCK membranes a hydrated state is implemented under UV irradiation, characterization UV–vis X‐ray photoelectron spectroscopic techniques. The crosslinked structure formed endows with desired properties, such as greatly...
发展了一种以哌啶乙酸盐为催化剂,催化邻羟基苯基β-二酮和不同系列醛进行Knoevenagel与O-Micheal串联反应的新方法,以较好的底物适应性及中等以上的产率,合成了16个2,3-二取代苯并二氢吡喃-4-酮和9个2,2-二取代苯并呋喃-3-酮类衍生物,并且该串联反应合成途径简捷,反应条件温和,催化剂廉价易得.
The alignment of liquid crystals (LCs) in LC-based optical devices determines the visual quality devices, and a simple pretreatment is necessary for LC alignment. Here, we present BiFeO3 (BFO) thin layer working as an layer, homogeneously aligning LCs after pre-thermal annealing treatment. Dramatic BFO bumps were observed during thermal process, corresponding enhancement wettability was detected from measurement tunable contact angles. bump sandwiched TN cell found to be perfectly aligned...
