For achieving a well-miscible and highly enhanced polyethylene/ultrahigh-molecular-weight polyethylene (PE/ UHMWPE) blend, which is an important blend for polyolefin materials with wide applications, tailored bonded interfacial intermolecular entanglement between the two phases was innovatively constructed via a facile reactive melt process through reaction between epoxy and carboxyl groups grafted onto polymer chains. The UHMWPE phase with obvious decreasing size and distribution was tightly embedded in a PE matrix, and the interfacial transition area increased dramatically, leading to forming a homogeneous and miscible blend. Meanwhile, the viscoelasticity and molecular entanglement density were improved remarkably, indicating an enhanced interfacial intermolecular diffusion, and a tight and robust dual network structure with covalent linkage and intermolecular entanglements was constructed in the blend. Obvious deformation with regular striation and many pulling-out UHMWPE fibrils were observed on an impact-fractured surface, and mechanical strength/toughness of the blend was remarkably enhanced. Furthermore, the wear rate and the friction coefficient were reduced significantly, and the worn surface presented smooth and flat features, confirming highly improved mechanical and tribological properties of the blend. This work provided a facile method to fabricate an enhanced PE/UHMWPE blend with application potential.

An article Thermostimulated luminescence of poly(diphenylenephthalide) films. Kinetics and mechanistic steps of irradiative processes WOS:000501355900027 published article about BASIS-SET; PHTHALIDE); POLYMERS; THERMOLUMINESCENCE; MODEL; ELECTROLUMINESCENCE in [Ovchinnikov, Mikhail Yu; Antipin, Vyacheslav A.; Khursan, Sergey L.] Ufa Inst Chem UFRC RAS, 71 Prospect Oktyabrya, Ufa 450054, Russia in 2020, Cited 59.

Kinetics of thermostimulated luminescence (TSL) of poly(diphenylenephthalide) (PDPh) films has been studied using mathematical modelling and DFT approximation. TSL of PDPh-film was considered to be arising from irradiative deactivation of diphenylene (DP) fragment of polymer chain in excited state formed upon recombination of the spatial separated ion-radical pairs generated by photoexcitation. Two parallel monomolecular transformations leading to excited DP have been revealed: the first path is characterized by the activation parameters of the kinetic rate constant k1 which equal to Al ti 105 sec 1 and Eat ti 70 kJ mol(-1). This path may be interpreted in terms of mechanical relaxation theory by segmental polymer mobility as electron transfer (ET) from phthalide (Ph) anion-to DP cation-radical. The second channel is supposed to be consist of two consecutive ET from triarylmethyl anion-radical to phthalide neutral (A2 ti 1 sec 1, Ea2 ti 20 kJ mol(-1)), and then to DP cation-radical (A3 N 104 sec 1, E,3 N 40 kJ mol(-1)) of the polymer chain indicating y- and fl-relaxation, respectively. The revealed mechanistic steps and electron retention efficiency estimated in B97-2/6-311 + G(d,p) approximation for the most probable anion-radicals may point out the key role of domino quantum tunneling in transfer and recombination of charges in PDPh films.

A new strategy is presented for enhancing the catalytic activity of cross-linked chitosan beads. More precisely, chitosan beads were cross linked with glutaraldehyde and then, vinyl functionalized. In the next step, the vinyl-functionalized beads were polymerized with the as-prepared 1-vinyl-3-butylimidazolium bromide to furnish polyionic liquid on beads. The resultant compositewas subsequently utilized as a metal-free catalyst for catalyzing some classic organic transformations, including Knoevenagel condensation reaction and syntheses of tetrahydrobenzo[b]pyrans and pyrano[2,3-d]pyrimidines in aqueous media under mild reaction conditions. It was found that the novel composite could efficiently promote all of the examined reactions to afford the corresponding products in high yields. Moreover, the catalyst exhibited high recyclability for all reactions. The comparative studies also approved that the activity of the composite was superior compared to cross-linked bead and polyionic liquid. (C) 2021 Elsevier B.V. All rights reserved.

Iron-catalysed hydroboration of imines and nitriles has been developed under low catalyst loading (1 mol%) in the presence of HBpin. A wide scope of substrate was found to smoothly undergo hydroboration, including electron releasing/withdrawing and halogen substitution patterns and cyclic substrates which all afforded the corresponding amines in good to excellent yields. Dihydroboration of nitriles was achieved conveniently under solvent free and additive free conditions. Promisingly, this catalytic system is also capable of the hydroboration of challenging ketimine substrates. Preliminary kinetic analysis of imine hydroboration reveals a first-order dependence on catalyst concentration. Both HBpin and 4-fluorophenyl-N-phenylmethanimine (1b) appear to exhibit saturation kinetics with first order dependence up to 0.5 mmol HBpin and 0.75 mmol imine, respectively. Temperature-dependent rate experiments for imine hydroboration have also been explored. Activation parameters for the hydroboration of (PhC)-Ph-F = NPh (1b) were determined from the Eyring and Arrhenius plots with Delta S-not equal, Delta H-not equal, and E-a values of -28.69 (+/- 0.3) e.u., 12.95 (+/- 0.04) kcal mol(-1), and 15.22 (+/- 0.09) kcal mol(-1), respectively.

A crosslinked polymer hybrid film, ipn-poly(vinyl cinnamate-graft-2-hydroxy ethyl methacrylate)-v-poly(ethylene glycol dimethacrylate) was synthesized by UV initiation using poly(vinyl cinnamate) (polyVCi), 2-hydroxy ethyl methacrylate (HEMA) monomer and ethylene glycol dimethacrylate (EGDMA) crosslinker. Benzophenone (Ph2CO), was used as the photoinitiator. The synthesis was optimized by changing the concentration of HEMA, Ph2CO, EGDMA, and UV irradiation time. PolyVCi undergoes photocrosslinking by 2+2 photocylo addition while the monomer/crosslinker couple, HEMA/EGDMA, undergoes free radical polymerization and crosslinking to form EGDMA crosslinked polyHEMA. Hence, simultaneous interpenetrating polymer network (IPN) formation occurs. The IPN consists of dual network of photocrosslinked polyVCi and EGDMA crosslinked polyHEMA chains. Grafting of HEMA/EGDMA chains on the polyVCi backbone also occur during network formation. The chemical functionalities present in the polyVCi/polyHEMA/polyEGDMA IPN films obtained were characterized by FTIR and SEM analysis. The contact angle measurements show enhanced wettability of the IPN film compared to polyVCi surface. TGA analysis confirms thermal stability of the films. Swelling behavior of the films examined in water and in ethanol reveals the effects of the chemical natures of polyVCi and polyHEMA as well as that of crosslinking on the hydrophilicity of the film. The films were tested as drug release matrices using flurbiprofen. The drug was loaded into the film matrix during IPN formation under UV irradiation. PolyVCi/polyHEMA/polyEGDMA IPN proved to be a suitable release matrix for flurbiprofen demonstrating controlled release behavior and zero-order release kinetics. The release mechanism was confirmed by its Ritger-Peppas n value (1.00 to 1.42), which indicates super case II release.

Sulfate radical (SO4 center dot(-)) and hydroxyl radical (center dot OH) generated from persulfate or peroxymonosulfate in AOPs have been widely used in contaminant degradation. Anthracene (ANT) can be decomposed by SO4 center dot(-) and center dot OH. The processes of ANT decomposition were investigated using theoretical calculations in this paper. The initiation reactions of ANT, anthrone, anthraquinone (ATQ) and 1-hydroxylanthraquinone (1-hATQ) by two radicals are studied. The highest free energy barriers of initiation reactions are 22.30 kcal mol(-1) in ATQ + SO4 center dot(-) reaction and 6.84 kcal mol(-1) in ATQ + center dot OH reaction. Comparing the rate constants of initiation reaction through the two radicals at 273-373 K, it can be concluded that SO4 center dot(-) and center dot OH both play important roles on the initiation of ANT and anthrone at lower pH. For ATQ and 1-hATQ, center dot OH is more important than SO4 center dot(-) in the initiation process, which indicates that the indirect influence of SO4 center dot(-) are more significant in the degradation processes of ATQ and 1-hATQ. This study provides theoretical confirmations for the mechanisms of reactions of ANT with SO4 center dot(-) and center dot OH, and evaluates the importance of SO4 center dot(-) and center dot OH according to the reaction rates. The work can give more insight into the degradation of PAHs by radicals.

Despite the well-established pharmacological properties of aromatic sulfonamides and the interest of introducing ferrocene into drugs, ferrocene sulfonamides have scarcely been studied. General synthetic methods using lithium bases to perform sulfonamide-directed deprotolithiation or the halogen dance reaction are here reported for the functionalization of N,N-dialkylferrocenesulfonamides toward various polysubstituted derivatives. Postfunctionalization of the ferrocenyl iodides by cross-coupling and lithium/iodine exchange reactions were also considered. Finally, the ligand behavior of new ferrocene phosphines in palladium-catalyzed coupling reactions was studied, and the reaction outcomes are viewed in light of DFT calculations.

Photoactive conjugated microporous polymers (CMPs) are emerging as porous materials capable of mediating the photocatalytic evolution of H-2 from water. In this study, we synthesized three pyrene-based CMPs (Py-F-CMP, Py-TPA-CMP, Py-TPE-CMP) through Sonogashira-Hagihara cross-couplings of 1,3,6,8-tetraethynylpyrene (Py-T, as a common monomer building block) with 2,7-dibromo-9H-fluorene (F-Br-2), tris(4-bromophenyl)amine (TPA-Br-3), and 1,1,2,2-tetrakis(4-bromophenyl)ethene (TPE-Br-4), respectively, in the presence of Pd(PPh3)(4) in DMF/Et3N. We then characterized the chemical structures, crystallinities, thermal stabilities, surface morphologies, and porosities of these three new CMPs. Brunauer-Emmett-Teller (BET) analyses and tests of photocatalytic H-2 production revealed that Py-TPA-CMP displayed the highest BET surface area (454 m(2) g(-1)), highest total pore volume (0.28 cm(3) g(-1)), highest H-2 evolution rate (19 200 mu mol h(-1) g(-1)), and highest apparent quantum yield (15.3%) when compared with those of Py-F-CMP, Py-TPE-CMP, and other organic porous materials.

Due to the fact that tyrosinase is responsible for biosynthesis and regulation of melanins and browning food products, tyrosinase inhibitors can be favorable agents in cosmetics and medicinal industries. A series of novel 2-hydroxy-4-methoxybenzohydrazide were designed, synthesized, and their new application as tyrosinase inhibitors was also disclosed. Based on in vitro tyrosinase inhibitory assay, 4d as the strongest inhibitor of tyrosinase with an IC50 value of 7.57 mu M showed approximately 2.5-fold better inhibition than kojic acid as positive control followed by two compounds 4b (IC50 = 8.19 +/- 0.25 mu M) and 4j (IC50 = 8.92 +/- 0.016) which displayed preferable tyrosinase inhibitory activity. Detailed investigations on the mechanism of action of the 4d reported mix type of inhibition. More importantly, molecular modeling assessments proposed the ability of 4d for potential interaction with Cu (metal)-His (residue) within tyrosinase active site. Overall, 4d is a promising candidate for the development of anti-tyrosinase agents.
