Carbohydrate-attached fullerene derivative for selective localization in ordered carbohydrate-block-poly(3-hexylthiophene) nanodomains
نویسندگان
چکیده
A carbohydrate-based fullerene derivative (AcMal7-C61) is designed, synthesized and applied to a lamellar-forming high-χ block copolymer system, poly(3-hexylthiophene)-block-peracetylated maltoheptaose (P3HT-b-AcMal7), actualize an ordered donor/acceptor (D/A) network. well-defined D/A lamellar structure of the P3HT-b-AcMal7:AcMal7-C61 blend with sub-10 nm domain features achieved upon thermal annealing. The AcMal7-C61 molecules are localized in phase-separated AcMal7 nanodomains without causing formation crystals while maintaining morphology up 1:0.5 (D:A) blending ratio. cross-sectional TEM observation GISAXS measurement reveals that P3HT-b-AcMal7 tends spontaneously organize into structures oriented perpendicular film surface at air/film interface orientation bottom depends on nature substrate.

A modified morphology was introduced for poly(3-hexylthiophene):phenyl-C71-butyric acid methyl ester (P3HT:PC71BM) bulk heterojunction (BHJ) solar cells by thermal and solvent annealing treatments in the presence of hydrophilic-hydrophobic block copolymers. Power conversion efficiency (PCE) plummet was prohibited during both thermal and solvent treatments for all BHJ devices modified wit...

Multivalent carbohydrate photoaffinity probes were developed based on gold nanoparticles (AuNPs) to provide a streamlined approach toward identification of carbohydrate-binding proteins. By using AuNPs as scaffolds, a carbohydrate ligand and a photoreactive group could be readily assembled on a probe in a modular fashion, which greatly accelerated the process of optimizing the probe design. The...

متن کاملLocalization of concanavalin A binding carbohydrate in Chlamydomonas flagella.
Chlamydomonas flagella are shown to possess two zones of concanavalin A (ConA) binding carbohydrate. The first zone, distinguished by a requirement for a prolonged labelling period for visualization of fluorescein isothiocyanate (FITC)-ConA fluorescence, is localized in the flagellar coat. The second zone is characterized by a rapid FITC- and [125I]ConA labelling subsequent to disruption of the...
متن کاملCarbohydrate and carbohydrate + protein for cycling time-trial performance.
Carbohydrate intake during endurance exercise delays the onset of fatigue and improves performance. Two recent cycling studies have reported increased time to exhaustion when protein is ingested together with carbohydrate. The purpose of the present study was to test the hypothesis that ingestion of a carbohydrate + protein beverage will lead to significant improvements in cycling time-trial pe...
