Quantum mechanical calculations of different monomeric structures with the same electroactive group to clarify the relationship between structure and ultimate optical and electrochemical properties of their conjugated polymers

Quantum mechanical calculations can clarify the relationship between structure and ultimate optical and electrochemical properties of conjugated polymers and produce a ground for the design of advanced materials for futuristic applications. Herein, we have examined the structural geometries and electronic properties of different monomeric structures with the same electmactive group to provide a relationship between calculated electronic properties of the monomers with the observed optical and electrical properties of their conjugated polymers. For this purpose, three different amide substituted 2,5-di(2-thienyl)-1H-pyrrole compounds containing a different number of electroactive groups have been synthesized and molecular structure optimizations have been carried out with the Density Functional Theory (DFT) calculations. FT-IR and NMR spectra of optimized geometries have been compared with experimental data. Furthermore, electronic properties of the monomeric structures such as chemical hardness/softness, ionization potential, HOMO-LUMO energy levels, electronegativity have been revealed and molecular electrostatic potential (MEP) surface has been calculated to determine the electrophilic and nucleophilic reactive attack regions of the molecules considered in this study. Finally, Total Density of State (TDOS), Partial Density of State (PDOS) and Mulliken charge analyses of these molecules have been carried out. Our calculations based on ab-initio methods for the monomers have been compared with the optical and electrical properties of their conductive polymers in order to understand interrelationship between monomer structure and polymer properties.

Interfacial Effect of Hydration Structures of Hydroxyapatite Nanoparticle Films on Protein Adsorption and Cell Adhesion States

The synthesized elliptical hydroxyapatite (E-HAp) and needle-like HAp (N-HAp) nanoparticles (NPs) were electrophoretically deposited on a gold (Au) substrate. A comparative study of the hydration layers on E-HAp, N-HAp, and Au films was achieved to investigate the interfacial effect of the hydration layers on the conformation of the adsorbed fibrinogen (Fgn) and fibroblast adhesion properties. As a result, the ratios of three types of hydration layer states (free water, intermediate water, nonfreezing water) analyzed by a Fourier transform infrared (FT-IR) spectral deconvolution of the O-H stretching absorption band were investigated. The ratio of the bonding water state (i.e., intermediate and nonfreezing water molecules) is almost the same between two HAp films, and the E-HAp film with an elliptical shape and smaller particle size exhibited the smallest ratio of nonfreezing water, which can suppress the denaturation of the adsorbed protein. Subsequently, FT-IR spectral deconvolution results of the amide I band of the adsorbed Fgn on the E-HAp film indicated the higher proportion of a-helix and beta-sheet structures as compared with those on the N-HAp and Au films, suggesting that the smaller proportion of nonfreezing waters would play a significant role in the stereoscopic Fgn conformation. In the culture of fibroblasts, FT-IR spectra of the adhered cells on the E-HAp, N-HAp, and Au films exhibited different absorbance intensities of the amide A, I, II, and III bands, suggesting a different amount of collagen-producing states by the cells, which were also supported by immunostaining results of the collagen type I. Therefore, the different hydration structures on the films clearly influenced the conformation of the adsorbed protein, and the preferential conformation was found at the interfaces between the fibroblasts and the underground E-HAp films.

Tryptophan-functionalized graphene quantum dots with enhanced curcumin loading capacity and pH-sensitive release

Tryptophan-conjugated graphene quantum dots (Trp-GQDs) were fabricated for the first time and loaded with curcumin (Cur) as a hydrophobic anticancer agent, to evaluate Cur loading capacity and release kinetics, as well as its cytotoxicity effect on human breast cancer cells. The GQDs were synthesized through a facile oxidation method, Trp was conjugated onto GQDs via amide bonds and Cur was loaded onto GQDs and Trp-GQDs by noncovalent interactions. TEM, FESEM, PL, UV-Vis, and FTIR analysis were used to study the nano-assemblies structural and spectral characterizations. The drug loading capacity increased by increasing the initial concentration of Cur, and by 23% after the conjugation of GQDs with Trp. A pH-sensitive release was also detected at pH 5.5 and 7.4. Moreover, the experimental release data of Cur from the two nano-assemblies at both pHs had the best compliance with the pseudo-second-order model. In-vitro cellular cytotoxicity on MCF-7 cells demonstrated the nontoxicity of the bare GQDs and Trp-GQDs nanocarriers. Considering the biocompatibility, traceability, high drug loading capacity, and pH-sensitivity of Trp-GQDs nanocarrier, it can be concluded that Cur/Trp-GQDs can be regarded as a promising candidate for drug delivery applications.

Synthesis of magnetic Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH: an efficient and reusable mesoporous catalyst for reduction and one-pot reductive-acetylation of nitroarenes

Magnetically recoverable Fe3O4@SiO2@Cu-Ni-Fe-Cr LDH was prepared under co-precipitation conditions. Characterization of the mesoporous catalyst was confirmed using Fourier-transformed infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, vibration sample magnetometer, Brunauer-Emmett-Teller, thermogravimetric, differential thermogravimetric analyses and transmission electron microscopy. Reduction of nitroarenes to the corresponding arylamines and one-pot reductive-acetylation of nitroarenes to acetanilides were carried out successfully by nanoparticles of the immobilized Cu-Ni-Fe-Cr layered double hydroxide on silica-coated Fe3O4 in water as a green solvent. All reactions were carried out within 6-22min affording arylamines and N-arylacetamides in high-to-excellent yields. Reusability of the core-shell nanocatalyst was examined six times without significant loss of its catalytic activity. [GRAPHICS]

Synthesis of cyclodextrin-pyrrole conjugates possessing tuneable carbon linkers

Cyclodextrins are naturally occurring cyclic oligosaccharides consisting of glucose units. The main feature of cyclodextrins is the ability to accommodate various lipophilic compounds in their interior, which determines them to be popular helpers to the mankind. However, there is still a demand for new derivatives for advanced applications. Herein, we report the synthesis of -cyclodextrin-pyrrole conjugates. Their preparation is based on an amide bond formation or copper(I)-catalysed azide-alkyne cycloaddition between -cyclodextrin and pyrrole derivatives. The main advantage of the synthetic approach lies in the possibility to attach the substituent in -position, because polypyrroles possessing a substituent in this position are generally more conductive than the N-substituted ones. Moreover, the presented synthetic route is general and allows tuning the properties (various types of connections and lengths) of a linker. The presented cyclodextrin-pyrrole derivatives thus open the door for new applications in the field of sensors or tissue engineering.

Synthetic studies toward bicyclic endoperoxides presenting polar side chains

We developed a synthetic strategy for the preparation of tetrahydrofuro[2,3-c][1,2]dioxane and 2,3,8-trioxa[3,3,1]nonanes bearing polar functional groups at C3 and C4, respectively. The synthetic strategy has been applied to the synthesis of 2,3,8-trioxa[3,3,1]nonanes bearing various amides and amines at C3 useful for structure-activity relationships investigation as antiplasmodial compounds. The synthesis of 1 and the reaction conditions identified for its conversion to amides and amines could pose the basis for the use of this class of endoperoxides also in conjugation with other drugs for polypharmacology approaches.

Fabrication of gelatin-poly(epichlorohydrin-co-ethylene oxide) fiber scaffolds by Forcespinning((R)) for tissue engineering and drug release

Gelatin/poly(epichlorohydrin-co-ethylene oxide) [GL : PECO] composites are synthesized in a one-step process by the incorporation of elastic PECO and diclofenac. [GL : PECO] fibers are prepared by Forcespinning((R)). GL : PECO fibers are capable of diclofenac, by conjugation via a labile amide linkage. Fourier transform infrared spectroscopy (FTIR) results confirmed the chemical reactions and hydrogen bonds between gelatin, PECO, and diclofenac. Diclofenac drug release from GL : PECO fibers are measured for 15 days and prolonged drug release is observed. The cell viability is studied with NIH/3T3 and excellent results are observed. The sustained drug release and cytotoxicity results reveal that GL : PECO fibers could be promising substitutes for skin tissue engineering, wound healing, and drug delivery.

Controllable Crystallization Behavior of Nylon-6/66 Copolymers Based on Regulating Sequence Distribution

Based on retaining the excellent properties of nylon-6 (PA6), nylon-6/66 copolymers (PA6/66) with well-controlled dimensional stability and toughness exhibit more potential applications. In this work, PA6/66 random copolymers were synthesized by melt copolymerization of epsilon-caprolactam and hexamethylene adipamide salt. The sequence distribution, crystal morphology, crystal forms, and melting and crystallization behavior of PA6/66 copolymers were systematically investigated by quantitative C-13 NMR, polarized optical microscopy, wide-angle X-ray diffraction, and differential scanning calorimetry, respectively. The crystallization activation energy increases from -286.43 to -212.43 kJ mol(-1) as the co-polyamide bond ratio increases from 0 to 0.22, while the deteriorating sequence regularity does not alter the original crystal morphology and crystal forms of PA6. Significantly, control over the crystallization behavior of PA6/66 copolymer has been obtained through finely regulating its sequence distribution. This work could provide theoretical support and new insights for controllable preparation of PA6 copolymers and ultimately be beneficial to extend their applications.

Enantiomeric resolution of ephedrine racemic mixture using molecularly imprinted carboxylic acid functionalized resin

In the current work, we prepared an enantio-selective imprinted resin adsorbent ((+)-EMIP) with remarkable affinity for (+)-ephedrine ((+)-Eph) enantiomer. The phenolic amide derived from 4-hydroxybenzoic acid (HBA) and (+)-Eph ((+)-Eph-HBA) was first synthesized via N,N’-diisopropylcarbodiimide (DIC) activation and then copolymerized with resorcinol and formalin. The template (+)-Eph was then expelled from the resin by alkaline degradation of the amide linkage and the finally obtained (+)-EMIP resin particles exhibited a considerable selectivity toward the (+)-Eph with a capacity reached 220 +/- 1 mg/g. Also, the selectivity studies indicated a higher affinity toward the imprinted (+)-Eph enantiomer as a result of the formation of configuration-matching receptor sites that were able to fit the targeted enantiomer better than its mirror-image. Moreover, the prepared resin was successfully employed in the chiral resolution of (+/-)-Eph racemate using batch technique with (+)-Eph 87.1% enantiomeric excess in the loading supernatant solution and (-)-Eph 44.6% excess in the recovery eluant solution.
