Deep-cavity cavitand TEMOA (2) is shown to assemble via the hydrophobic effect into tetrameric and hexameric assemblies. With inner volumes of 1400-1500 angstrom(3) and 3200-3700 angstrom(3) respectively, these well-defi...
A new concept of "tunable ionic liquid (IL)-H2O interfacial synthesis" is proposed and used practically in the synthesis of Ag films with various morphologies at the IL-H2O interface by employing ILs with different anion...
The first catalytic asymmetric pseudo five-component (AB(2)C(2) type) reaction is reported. A spirocyclic chiral phosphoric acid catalyzed one-pot multicomponent reaction of aromatic aldehydes, anilines and beta-ketoeste...
This communication describes a chiral base-catalyzed asymmetric [1,3]-proton shift of trifluoromethyl ketimines, giving a wide variety of trifluoromethyl aldimines containing various functional groups with up to 94% ee.
A simple, novel "one-pot" approach was developed for the preparation of organic-silica hybrid monoliths. Two clickable monoliths functionalized with either azido or alkynyl moieties were prepared. The clickable monoliths...
A new and efficient catalytic approach to the synthesis of 3-acylindoles under Pd-Cu-cocatalyzed oxidative conditions is demonstrated. tert-Butyl hydroperoxide (TBHP) acts not only as the oxidant, but also as an oxygen s...
A short and atom-efficient strategy to obtain a series of pyrazolo(benzo)thienoquinolines is developed. Alternative catalytic systems for the key intramolecular direct heteroarylation of arenes are presented and include ...
Z907-sensitized solar cells incorporating a phenyl-capped aniline tetramer (EPAT) as a substitute of the iodine/iodide redox couple in the electrolytes produce an enhanced open-circuit voltage and short circuit photocurr...
Flowing supercritical CO2 was used to activate a cross section of microporous coordination polymers (MCPs) directly from DMF, thus avoiding exchange with a volatile solvent. Most MCPs displayed exceptional surface areas ...
It is demonstrated that 1,4-phenylene diisocyanide (PDI)-gold oligomers can spontaneously bridge between gold nanoparticles on mica, thereby providing a strategy for electrically interconnecting nanoelectrodes. The barri...
Organogels made of pyridine-end oligo-p-phenylenevinylenes with tartaric acid exhibit remarkable J-aggregation induced red-shifts (Dk = 55 nm) and notable chirality transcription. Induction of liquid-crystalline behavior...
A new approach for selective modification of cysteine-containing peptides through gold-mediated oxidative allene-thiol coupling reaction in aqueous medium is developed.
Silk scaffolds having biomimetic hierarchical porous structures were achieved by carefully tuning liquid-liquid separation in regenerated silk fibroin solutions. Such scaffolds show greatly enhanced cellular responses.
Triphenylhalophosphonium halides, Ph3PX2, form crystals comprising bridged linear cations [Ph3P-X-X-X-PPh3](+) where the X-3 bridge is shortened from 6.56 angstrom in Cl-Cl-Cl to 6.37 angstrom in the Br-Br-Br system. It ...
Nickel diselenide (NiSe2) has been synthesized and applied as a counter electrode (CE) of dye-sensitized solar cells (DSSCs) for the first time, which displays remarkable catalytic activity in the reduction of I-3(-). Th...
A transparent MoS2-graphene nanosheet (GNS) nanocomposite counter electrode (CE) was incorporated into a Pt-free dye-sensitized solar cell (DSC). The DSC assembled with the transparent MoS2-GNS CE therefore exhibited an ...
