Wafer-Scale Diisopropylammonium Bromide Films for Low-Power Lateral Organic Ferroelectric Capacitors

Organic ferroelectrics, particularly the polymer polyvinylidene fluoride and its copolymer polyvinylidene fluoride-trifluoroethylene, have received much attention owing to their low cost, flexibility, and convenient thin film fabrication. However, development of this outstanding material for electronic applications is significantly impeded by its attributes of large coercive electric fields and poor spontaneous polarization. While the recent breakthroughs reveal that several kinds of molecular ferroelectrics (e.g., diisopropylammonium bromide (DIPAB)) can exhibit excellent properties comparable to inorganic ferroelectrics, it is still difficult to obtain high-quality continuous thin films for ferroelectric devices with high performance. In this work, a simple solution strategy is used for the preparation of large-area high crystallinity or even single-crystal DIPAB films. Subsequently, planar ferroelectric capacitors are developed with large in-plane ferroelectric polarization. These capacitors possess excellent memory function with small operating voltages (1-3 V), and a record remnant polarization of 13 mu C cm(-2) for organic ferroelectric devices. The findings have the potential to pave the way for the substitution of conventional ferroelectric polymers with DIPAB films for future organic ferroelectric devices.

Solid polymer electrolytes based on poly(vinyl alcohol) incorporated with sodium salt and ionic liquid for electrical double layer capacitor

Solid polymer electrolyte (SPE) based on poly(vinyl alcohol) (PVA) as a host polymer, sodium trifluoromethanesulfonate (NaTf) salt, and 1-butyl-3-methylimidazolium bromide (BmImBr) ionic liquid is fabricated using solution casting technique. The ionic conductivity, crystallinity, composition and thermal stability were characterized by electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA), respectively. The optimum ratio between PVA and NaTf salt to obtain highest ionic conductivity was found to be as 60:40. The inclusion of BmImBr ionic liquid into the optimized PVA-based SPE significantly enhanced the ionic conductivity. XRD pattern indicated the successful dissolution of NaTf salt and complexation of BmImBr ionic liquid in the host polymer which has also been confirmed by FTIR spectra. The thermally stable SPE is suitable for electrical double layer capacitor (EDLC) application. The electrochemical studies of GPE for EDLC showed promising performance producing specific capacitance of 16.32 F g(-1).

Differential effect of surfactants tetra-n-butyl ammonium bromide and N-Cetyl-N, N, N-trimethyl ammonium bromide bound to nano-cellulose on binding and sustained release of some non-steroidal anti-inflammatory drugs

Nano crystalline cellulose (NCC) modified with cationic surfactant CTAB (N-Cetyl-N, N, N-trimethyl ammonium bromide) proved as effective drug delivery excipient for sustained release of non-steroidal anti-inflammatory drugs (NSAIDs). In the present work, our purpose was to study the effect of another cationic surfactant TBAB (tetra-n-butyl ammonium bromide) used to modify NCC on binding and sustained release of hydrophobic NSAIDs. NCC modified TBAB was characterized by FTIR & TGA analysis. TBAB-NSAID interactions have been assessed using CHEM3D. The sustained release character was monitored by time dependent serum protein protecting and time dependent anti-cathepsins activities. The NCC-TBAB exhibited the binding efficiency for NSAIDs in the range of 42-25% depending upon the hydrophobicity of NSAID and released the drug up to 60 min. The research problem added to the existing knowledge of suitable surfactants required to change the hydrophilic nature of NCC to act as carrier for hydrophobic drugs. TBAB surfactant having shorter alkyl chain length exhibited lower binding efficiency and decreased sustain release of drugs as compared to CTAB having longer alkyl chain length.

Highly Regioselective 5-endo-tet Cyclization of 3,4-Epoxy Amines into 3-Hydroxypyrrolidines Catalyzed by La(OTf)(3)

Highly regioselective intramolecular aminolysis of 3,4-epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)(3) catalyst and (2) excellent regioselectivity for anti-Baldwin 5-endo-tet cyclization. This reaction affords 3-hydroxy-2-alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed that the regioselectivity might be attributed to distortion energies of epoxy amine substrates. The use of this reaction was demonstrated by the first enantioselective synthesis of an antispasmodic agent prifinium bromide.

Electrochemical CO2 Fixation to alpha-Methylbenzyl Bromide in Divided Cells with Nonsacrificial Anodes and Aqueous Anolytes

Electrocarboxylation of organic halides represents a CO2 utilization strategy and a green alternative for the synthesis of many industrially relevant carboxylic acids. However, current electrocarboxylation methods rely on the utilization of sacrificial metal anodes, which are not sustainable, require high voltages, and complicate the understanding of the reaction mechanism. Here, we demonstrate the feasibility of performing electrocarboxylation reactions in divided cells with aqueous anolytes and nonsacrificial anodes, thereby eliminating the reliance on sacrificial anodes and opening the door for coupling of this important reduction process with various electrooxidation reactions requiring aqueous electrolytes. Specifically, we report a detailed study of electrocarboxylation of (1-bromoethyl)benzene at a silver cathode coupled with an oxygen evolution reaction at a platinum anode in a divided cell with organic and aqueous compartments separated by ion-exchange membranes of different types. We examine how operating parameters, including membrane type, applied potential, substrate concentration, electrolyte, and temperature affect the overall process and the reaction product distribution. Based on the extensive experimental results, we propose a detailed mechanism for major electrochemical product formation accounting for both aprotic and protic environments. Systematic analysis and mechanistic insights presented in this study are expected to enable a rational catalyst, electrolyte, and system design tailored to electroorganic CO2 fixation with different organic substrates to obtain industrially relevant carboxylic acids at practical potentials and currents.

Effect of Halogen Ions on the Photocycle of Fluorescent Carbon Nanodots

Carbon dots (C-dots) are well-known for their strong sensitivity to the environment, which reflects on intensity and shape changes of their fluorescence, induced by various interacting ions and molecules in solution. Although these interactions have been extensively studied in the last few years, especially in view of their possible sensing applications, the existing works have mostly focused on the quenching of C-dot fluorescence induced by metal cations. In fact, these latter easily bind to C-dots surfaces, which are negatively charged in most cases, promoting an electron transfer from the surface to them. Much less is known from the literature on the effect induced on C-dots by prototypical negative species in solutions, motivating more systematic studies on this different class of interactions. Here, we analyzed the effect of halogen ions on the fluorescence of C-dots, by combining steady-state optical absorption and photoluminescence, time-resolved fluorescence and femtosecond pump/probe spectroscopy. We demonstrate a quenching effect of C-dots fluorescence in the presence of halogen ions, which becomes more and more pronounced with increasing atomic number of the halogens, being negligible for chloride, appreciable for bromide and stronger for iodide. We find that quenching is mostly static, due to the binding of halogen ions on suitable surface sites at C-dots surfaces, while collisional quenching becomes obvious only at very high iodide concentrations. Finally, nanosecond and femtosecond time-resolved spectroscopies provide information on the quenching mechanism and time scales. Based on these data, we propose that the fluorescent state is deactivated by intersystem crossing to a dark triplet state, induced by close-range interactions with the heaviest halogen ions.

The bromide-bromomethyl radical dimer complex: Anion photoelectron spectroscopy and CCSD(T) calculations

The gas phase anion photoelectron spectrum associated with the bromide-bromomethyl radical is presented. The stabilisation energy and electron binding energy, a property corresponding to the electron affinity of the neutral complex, are determined. Ab initio MP2 optimisations (with additional CCSD(T) energies) found two forms of the complex, a hydrogen bonded complex and a halogen bonded complex. The halogen bonded complex was found to exhibit C-2v symmetry and the hydrogen bonded complex exhibited C-s symmetry. Comparison between the experimental data and the computational data allow conclusions to be drawn about the structure of the experimentally observed species.

Poly(glycerol sebacate) nanoparticles for ocular delivery of sunitinib: physicochemical, cytotoxic and allergic studies

Poly(glycerol sebacate) (PGS) is a new biodegradable polymer with good biocompatibility used in many fields of biomedicine and drug delivery. Sunitinib-loaded PGS/gelatine nanoparticles were prepared by the de-solvation method for retinal delivery and treatment of diabetic retinopathy. The nanoparticles were characterised by Fourier-transform infrared and differential scanning calorimetry. The effects of different formulation variables including drug-to-carrier ratio, gelatine-to-PGS ratio, and glycerine-to-sebacate ratio were assessed on the encapsulation efficiency (EE%), particle size, release efficiency (RE), and zeta potential of the nanoparticles. The in vitro cytotoxicity of PGS/gelatine nanoparticles was studied on L929 cells. Draize test on rabbit eyes was also done to investigate the possible allergic reactions caused by the polymer. Glycerine/sebacic acid was the most effective parameter on the EE and RE. Gelatine-to-PGS ratio had the most considerable effect on the particle size while the RE was more affected by the glycerine/sebacic acid ratio. The optimised formulation (S(1)G(0.7)D(21.2)) exhibited a particle size of 282 nm, 34.6% EE, zeta potential of -8.9 mV, and RE% of about 27.3% for drug over 228 h. The 3-(4,5-dimethylthuazol-2-yl)-2,5-diphenyltetrazolium bromide assay indicated PGS/gelatine nanoparticles were not cytotoxic and sunitinib-loaded nanoparticles were not toxic at concentrations <36 nM.
