    - MACROMOLECULES - Year 2012

    Novel, semicrystalline polyamides and copolyamides were synthesized from a new carbohydrate-based diamine, namely isoidide-2,5-dimethyleneamine (IIDMA). In combination with 1,6-hexamethylene diamine (1,6-HDA) as well as the biobased sebacic acid (SA) or brassylic acid (BrA), the desired copolyamides were obtained via melt polymerization of the nylon salts followed by a solid-state polycondensation (SSPC) process. Depending on the...

  • Anion recognition by n,n'-diarylalkanediamides
    Publication

    The preparation of N,N'-diarylalkanediamides from respective aliphatic dicarboxylic acidesand 4-nitroaniline via microwave-promoted reactions is presented. The most positive effect of microwave irradiation was observed for N,N'-bis(4-nitrophenyl)butanediamide. Anion binding studies on the obtained diamides were carried out in DMSO and acetonitrile using UV-vis and 1H NMR spectroscopy. A mechanism for selective fluoride recognition...

    - JOURNAL OF APPLIED PHYSICS - Year 2012

    Domieszkowany jodem oraz domieszkowany jodem ditlenek tytanu uzyto jako warstwę buforową w ogniwie ITO/X-TiO2?P3HT-PCMB /MnO2/ Ag.Warswty X-TiO2 nalożono metodą spin-coatingu z zawiesiny nanocząstek w DMSO. Jednorodne struktury scharakteryzowane pod względem morfologii mikroskopowo metodą AFM. Charakterystyka prądowo-napięciowa urzdzeń wskazuje iż domieszkowany jodem TiO2 pozwala osiągnąć lepsze parametry PCE (1,67%) i prąd zwarcia...

  • Bis(azobenzocrown ether)s-synthesis
    Publication

    Syntezowano nowe związki bisazobenzokoronowe różniące się wielkością makropierścienia i długością łańcucha łączącego oba pierścienie makrocykliczne. Związki te wykorzystano jako jonofory w membranach klasycznych i miniaturowych elektrod jonoselektywnych. Przeprowadzono również badania dotyczące kompleksowania soli litowców i berylowców w roztworze acetonitrylowym z wykorzystaniem spektrofotometrii UV-VIS oraz zbadano strukturę...

  • Chromogenic amides of pyridine-2,6-dicarboxylic acid as anion receptors

    The synthesis of simple, chromogenic pyridine-2,6-dicarboxylic acid amides, derivates of isomeric nitroanilines and aminonitrophenols, and their ion binding properties are described. The ligands' response to ionic species was examined by naked eye and was studied with the use of UV-Vis spectroscopy in DMSO and its mixture with water. The effect of the localisation and the type of the substituents in aromatic rings were discussed....

    - PROGRESS IN ORGANIC COATINGS - Year 2014

    Linear and branched bio-based semi-aromatic (co)polyesters were evaluated as resins for solvent-basedand powder coatings. Dimethyl-2,5-furandicarboxylate (DMF), 2,3-butanediol and various multifunc-tional comonomers were used to synthesize amorphous hydroxyl-end-capped (co)polyesters. The resinswere cross-linked using the -caprolactam blocked trimer of isophorone diisocyanate. Both the solvent-based and powder coatings proved to...

  • Chromium-Catalyzed CO2–Epoxide Copolymerization
    Publication

    - ORGANOMETALLICS - Year 2014

    Iminopyrrole, aminopyrrole, and aminophosphine ligands were complexed with various chromium sources, producing eight complexes that were tested for their catalytic behavior toward epoxide–CO2 copolymerization. As elucidated by MALDI-TOF-MS, copolymerizations afforded polycarbonates and poly(ether-carbonates) exhibiting linear or cyclic topologies.
