Core Cross‐Linked Micelle‐Based Nanoreactors for Efficient Photocatalysis
Chemistry - An Asian Journal - Tập 8 Số 11 - Trang 2807-2812 - 2013
AbstractStable nanoscale cross‐linked polymer micelles containing Ru complexes
(Ru‐CMs) were prepared from monomethoxy[poly(ethylene
glycol)]‐block‐poly(L‐lysine) (MPEG‐PLys) and [(bpy)2Ru(fmbpy)](PF6)2
(bpy=bipyridine, fmbpy=5‐formy‐5′‐methyl‐2,2′‐bipyridine). To stabilize the
micelles, bifunctional glutaraldehyde was used as a cross‐linker to react with
the free amino groups of the PLys block. A...
Label‐Free, Electrochemical Quantitation of Potassium Ions from Femtomolar Levels
Chemistry - An Asian Journal - Tập 10 Số 10 - Trang 2169-2175 - 2015
AbstractIn this communication, a label‐free and sensitive electrochemical method
to detect potassium ions is proposed. The conducting polymer polypyrrole was
used as both an anchor for the probe and a transducer of the detection event. A
K+‐specific G‐rich aptamer was applied as a recognition element, which folded
into the G‐quadruplex structure in the presence of K+, and this resulted in an
incre...
Photoelectrochemical Hydrogen Peroxide Production from Water on a WO3/BiVO4 Photoanode and from O2 on an Au Cathode Without External Bias
Chemistry - An Asian Journal - Tập 12 Số 10 - Trang 1111-1119 - 2017
AbstractThe photoelectrochemical production and degradation properties of
hydrogen peroxide (H2O2) were investigated on a WO3/BiVO4 photoanode in an
aqueous electrolyte of hydrogen carbonate (HCO3−). High concentrations of HCO3−
species rather than CO32− species inhibited the oxidative degradation of H2O2 on
the WO3/BiVO4 photoanode, resulting in effective oxidative H2O2 generation and
accumulatio...
Cu‐catalyzed Synthesis of Quinolines by Dehydrogenative Reaction of 2‐Aminobenzyl Alcohol and Ketones: A Combined Experimental and Computational Study
Chemistry - An Asian Journal - Tập 17 Số 22 - 2022
AbstractQuinoline derivatives are important moieties in bioactive molecules and
advanced materials. However, an efficient strategy to synthesize quinoline
derivatives remains challenging. Herein, we describe an efficient and practical
method for the synthesis of quinolines by Cu‐catalyzed cyclization of 2‐amino
benzyl alcohol with ketones (or secondary alcohols) via an acceptorless
dehydrogenation...
Photocatalytic Advanced Oxidation Processes for Water Treatment: Recent Advances and Perspective
Chemistry - An Asian Journal - Tập 15 Số 20 - Trang 3239-3253 - 2020
AbstractNowadays, an ever‐increasing variety of organic contaminants in water
has caused hazards to the ecological environment and human health. Many of them
are persistent and non‐biodegradable. Various techniques have been studied for
sewage treatment, including biological, physical and chemical methods.
Photocatalytic advanced oxidation processes (AOPs) have received increasing
attention due to...
High‐Performance Dye‐Sensitized Solar Cells Based on Phenothiazine Dyes Containing Double Anchors and Thiophene Spacers
Chemistry - An Asian Journal - Tập 9 Số 1 - Trang 357-366 - 2014
AbstractA series of new push–pull phenothiazine‐based dyes (HL1, HL2, HL3, HL4)
featuring various π spacers (thiophene, 3‐hexylthiophene,
4‐hexyl‐2,2′‐bithiophene) and double acceptors/anchors have been synthesized,
characterized, and used as sensitizers for dye‐sensitized solar cells (DSSCs).
Among them, the best conversion efficiency (7.31 %) reaches approximately 99 %
of the N719‐based (7.38 %)...
Structural modulation induced by cobalt‐based ionic liquids for enhanced thermoelectric transport in PEDOT:PSS
Chemistry - An Asian Journal - Tập 16 Số 18 - Trang 2740-2744 - 2021
AbstractPoly(3,4ethylenedioxythiophene):poly(4‐styrenesulfonate) (PEDOT:PSS) has
been intensively studied for its thermoelectric applications. Structural
modulation to improve crystalline ordering, chain conformation and film
morphology is a promising way to decouple the trade‐off between conductivity and
Seebeck coefficient and thus improve the thermoelectric power factor. Post
treatment with ion...
Ir(III)‐Catalyzed C7‐Position‐Selective Oxidative CH Alkenylation of Indolines with Alkenes in Air
Chemistry - An Asian Journal - Tập 9 Số 5 - Trang 1257-1260 - 2014
AbstractAn efficient method for C7‐position‐selective alkenylation of
N‐substituted indolines with alkenes is reported. Various 7‐alkenylindolines
were obtained in moderate to excellent yields in air in the presence of
catalytic amounts of [Cp*IrCl2]2, AgOTf, and Cu(OAc)2. The protocol relies on
the use of a carbonyl or carbamoyl group on the nitrogen atom of indoline as a
directing group and is p...
Removal of Acid Orange G Azo Dye by Polycation‐Modified Alpha Alumina Nanoparticles
Chemistry - An Asian Journal - Tập 18 Số 17 - 2023
AbstractHighly positively charged poly(vinyl benzyl trimethylammonium chloride)
(PVBMA) was successfully synthesized with approximately 82% of yield. The PVBMA
was characterized by the molecular weight (Mw) of 343.45 g mol−1and the
molecular weight distribution, (Đ) of 2.4 by1H NMR and SEC measurements. The
PVBMA was applied as an effective agent for α‐Al2O3surface modification in the
adsorptive r...
Supramolecular Tilt Chirality Derived from Symmetrical Benzene Molecules: Handedness of the 21 Helical Assembly
Chemistry - An Asian Journal - Tập 2 Số 2 - Trang 230-238 - 2007
AbstractAchiral molecules can form aggregates with chirality. This depends on
the relative position of the molecules, in other words, the tilt of the
molecules (so‐called supramolecular tilt chirality). In this paper, we describe
supramolecular chirality appearing in a 21 column composed of symmetrical
benzene molecules, which is formed in the host cavity of inclusion crystals of
cholic acid. More...
