Amide functionalized anthradithiophenes (ADTs) play active acceptor roles in polymer bulk-heterojunction solar cells. The first separation of ADT isomers is reported, and the regiochemistry of the ADT has significant impact on crystal packing and solar cell performance. Cell efficiency up to 0.80%, due in large part to high open-circuit voltage (V(OC) > 1.0 V), is achieved in bulk-heterojunctio...

The effective life-time of new antimicrobials until the appearance first resistant strains is steadily decreasing, which discourages incentives for commercialization required clinical translation and application. Therefore, development should not only focus on better killing antimicrobial-resistant strains, but as a paradigm shift developing that prevent induction resistance. Heterofunctionaliz...

The study of the tryptic digestion of poly-L-lysine (Katchalski, 1951; Waley & Watson, 1953) has shown that lysine oligopeptides appear duringthe reaction. A better understanding of the mode of action of trypsin on the high-molecular-weight peptide might be gained by a study of the action of the enzyme on a homologous series of lysine peptides (for a preliminary note see Katchalski, Berger & Le...

The immobilization efficiency of the complexes of oligonucleotide/poly(L-lysine) onto Poly(Styrene/Maleic Acid), PSMA, and Poly(Styrene/Maleic Anhydride), PSMAA, has been investigated using X-ray photoelectron spectroscopy and atomic force microscopy (AFM) in conjugation with fluorescence-based measurements of DNA attachment. A mono-molecularly thin layer of either electrostatically or covalent...

Conformations of achiral and chiral aromatic homo-polypeptoids of Nphe, Nspe and Nrpe were studied by quantum mechanics and molecular dynamics approaches. The amide bond geometry in model peptoids Ac-X-NMe2 could be both cis and trans and the Nphe peptoids adopted degenerate conformations of opposite handedness with Φ, Ψ values of ~ ± 120o, ± 150o with trans amide bond geometry. This degeneracy...

The hydration of omega-gliadins and party deamidated and esterified omega-gliadins has been studied by Fourier transform IR spectroscopy. The secondary structure of the fully hydrated proteins was a mixture of beta-turns and extended chains, with a small amount of intermolecular beta-sheets. The absorption of the glutamine side chain amide groups contributed considerably to the amide I band wit...

A new concept for simultaneous detection of two model proteases based on immobilized fluorescently labelled peptides was developed and evaluated. Each probe composed a carrier modified by poly(ethylene glycol) (PEG) chains, specifically cleavable linker, fluorescent dye incorporated in the peptide tail. Based single excitation–double emission fluorescence response liberated fluorophores caused ...

A new aromatic diamine monomer containing ether linkage based on the phenanthrimidazole ring, ‎1,1´-(4,4´- oxy bis(1,4-phenylene))bis(2-(4-aminophenyl)-1H-phenanthro[9,10-d]imidazole) was synthesized through four-‎components condensation of 4,4´-diamino diphenyl ether, 4-nitrobenzaldehyde, phenanthrene-9,10-dione and ammonium ‎acetate in presence of acetic acid, followed by palladi...
