Thiophene hydrodesulfurization on clean and sulfur covered MoP(001): Theoretical survey of the positive effect of sulfur deposition on the catalytic performance.
Molybdenum phosphide (MoP) has been extensively experimentally shown to possess high and surprisingly increasing hydrodesulfurization (HDS) activities during the HDS process. In order to understand the HDS mechanism, we investigate the HDS of thiophene on clean and single-sulfur-atom-modified MoP(001) using self-consistent periodic density functional theory (DFT). Thiophene strongly prefers flat...

A planar dithiafulvene based sensitizer forming J-aggregates on TiO2 photoanode to enhance the performance of dye-sensitized solar cells.
A newly planar dithiafulvene sensitizer (DTF-C4) trending to form J-aggregates on the surface of mesoporous TiO2 by simply rinsing with a poor solvent acetonitrile was synthesized. We further show that the self-assembled J-aggregates optimized the TiO2surface utilization, enhanced the light harvesting ability by broadening and red-shifting the absorption, and suppressed the electron recombinatio...

[Compos. Sci. Technol.]Development of wave-transparent, light-weight composites combined with superior dielectric performance and desirable thermal stabilities
In this paper, a novel interfacial compatibilizer of soluble epoxy-terminated poly (p-phenylene-2, 6-benzobisoxazole) precursor (epoxy-prePBO) was synthesized to modify bisphenol A cyanate ester (BADCy) resin via copolymerization. Compared to PBO fibers/BADCy wave-transparent composites, the obtained PBO fibers/epoxy-prePBO modified BADCy (PBO fibers/PBO-co-BADCy) wave-transparent composite with...

(Macromolecules) Vanillin-derived High-performance Flame Retardant Epoxy Resins: Facile Synthesis and Properties
Lignin derivative vanillin when coupled with diamines and diethyl phosphite followed by reaction with echichlorohydrin yields high-performance flame retardant epoxy resins. Biorenewable and environment-friendly flame retardant alternatives to bisphenol A epoxy resins (having plenty of applications such as coatings, adhesives, composites, etc.) have captured great attention due to their ecologica...

High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
A novel high-performance polyindole containing a pyridine ring (P1)was successfully prepared by the catalyst-free nucleophilic substitution polycondensation of 4-hydroxyindole with 2,6-difluoropyridine via a C?N and C?O coupling reaction process. This semirigid polyindole P1 exhibits good thermal stability, and it can be dissolved well in common organic solvents. Fluorescent spectral studies ind...

Synthesis of High-Performance Polymers via Copper-Catalyzed Amination of Dibromoarenes with Primary Aromatic Ether Diamines
In this paper, we introduce three high-performance polymers with similar structures, poly(imino ether ketone) (PIEK)s, which are synthesized by the ligand free copper-catalyzed C-N cross coupling reaction of aryl halides and primary aromatic diamines at moderate temperature. The influence of the solvents, base, temperature, and catalyst ligands on the polycondensation reaction is investigated. T...

Design and preparation of high performance amine-based poly(ether ketone)s with strong photonic luminescence
Amine-based poly(ether ketone)s (A-PEKs), as novel high-performance functional polymers, have been obtained by the polycondensation of dibromo ketones with aromatic ether diamines via palladium-catalyzed aryl amination reaction. The structures of the polymers are characterized by means of FT-IR, 1H NMR spectroscopy and elemental analysis, the results show a good agreement with the proposed struc...

Poly(vinylidene chloride)-Based Carbon with Ultrahigh Microporosity and Outstanding Performance for CH4 and H2 Storage and CO2 Capture
Poly(vinylidene chloride)-based carbon (PC) with ultrahigh microporisity was prepared by simple carbonization and KOH activation, exhibiting great potential to be superior CO2, CH4, and H2adsorbent at high pressures. The CO2 uptake for pristine PC is highly up to 3.97 mmol/g at 25 °C and 1 bar while the activated PC exhibits a slightly lower uptake at 1 bar. However, the activated PC has an outst...

Large Surface Area Ordered Porous Carbons via Nanocasting Zeolite 10X and High Performance for Hydrogen Storage Application
We report the preparation of ordered porous carbons for the first time via nanocasting zeolite 10X with an aim to evaluate their potential application for hydrogen storage. The synthesized carbons exhibit large Brunauer-Emmett-Teller surface areas in the 1300–3331 m2/g range and pore volumes up to 1.94 cm3/g with a pore size centered at 1.2 nm. The effects of different synthesis processes with py...
