We report the synthesis of multifunctional block copolymers (BCPs) showing a high Flory–Huggins interaction parameter (χ), which enable sub-10 nm line-space structures for low degree polymerization (N). The χ BCPs are based on poly(3,4-dihydroxystyrene)–block-poly(4-trimethylsilylstyrene) (PDHS-b-PTMSS) architecture. controlled PDHS-b-PTMSS precursors was performed using user-friendly sequentia...

Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...

We characterized the interactions of meso-tetrakis(4N-(2-hydroxyethyl)pyridinium-4-yl) porphyrin (TEtOHPyP4), meso-tetrakis(4N-allylpyridinium-4-yl) porphyrin (TAlPyP4), and meso-tetrakis(4N-metallylpyridinium-4-yl) porphyrin (TMetAlPyP4) with the poly(rA)poly(rU) and poly(rI)poly(rC) RNA duplexes between 18 and 45 degrees C by employing circular dichroism, light absorption, and fluorescence in...

We consider the problem of learning unions of rectangles over the domain [b]n, in the uniform distribution membership query learning setting, where both b and n are “large”. We obtain poly(n, log b)-time algorithms for the following classes: • poly(n log b)-way MAJORITY of O( log(n log b) log log(n log b))-dimensional rectangles. • Union of poly(log(n log b)) many O( log (n log b) (log log(n lo...

Block copolymers based on poly(vinylamine) and poly(N-isopropylacrylamide), PVAmm-b-PNIPAMn, were synthetized by hydrazinolysis of poly(N-vinylphthalimide) copolymers, PVPIm-b-PNIPAMn, obtained RAFT polymerization. The effect molar mass pH the thermoresponsive aggregation properties these polymers in aqueous solution was studied with UV–vis spectroscopy, differential scanning calorimetry, NMR s...

Konjugierte Polymere sind attraktive Materialien für die photoelektrochemische Wasserstoffentwicklungsreaktion (PEC-HER) unter neutralen oder sauren Bedingungen. Jedoch zeigen sie im alkalischen Medium immer noch eine geringe PEC-HER-Leistung aufgrund des Fehlens von Wasserdissoziations-Zentren. Hier wir, dass durch Anpassung konjugierten acetylenischen Polymers (CAPs) Poly(diethinylthieno[3,2-...

The effects of blend weight ratio and polyester block length of methoxy poly(ethylene glycol)-b-poly( d, l-lactide) (MPEG- b-PDLL)/methoxy poly(ethylene glycol)- b-poly(ϵ-caprolactone) (MPEG- b-PCL) blends on nanoparticle characteristics and drug release behaviors were evaluated. The blend nanoparticles were prepared by nanoprecipitation method for controlled release of a poorly water-soluble m...

A dithiocarbamate chain transfer agent (CTA) based on Z-group substituted with a diphenyl amine (–NPh2) moiety is selected for the synthesis of statistical and diblock copolymers ethylene vinyl acetate via reversible addition–fragmentation polymerization. Benefiting from good growth control polyethylene (PE), poly(vinyl acetate) (PVAc), poly(ethylene-co-vinyl (EVA) achieved this CTA, linear typ...
