A diastereoselective Henry reaction of chiral aldehydes with nitroalkanes was developed using a chiral sulfonyldiamine (L1)-CuCl complex. The reaction of (R)-2-phenylpropanal and nitromethane was smoothly catalyzed by th...
The substantial kinetic barrier to molybdenum nitride-alkyne metathesis is facilitated by precomplexation of the borane Lewis acid B(C6F5)(3), providing convenient access to metathesis-active molybdenum alkylidynes. Spec...
The activation of dihydrogen by frustrated Lewis pairs (FLP) is initially driven by the electric field created inside a molecular cavity [Angew. Chem., Int. Ed., 2010, 49, 1402]. Here we test the accuracy of different de...
Rapid CuAAC cross-coupling reactions catalyzed by CuBr/PMDETA in toluene afforded complex architectures from functional polymeric cyclic blocks. Various topologies (from paddle-like to 3-arm stars) rapidly formed with hi...
Fluorescent labeling of human mesenchymal stem cells (hMSCs) is essential for their study in vitro and in vivo. Here, we report a new chemical biodelivery method for labeling hMSCs using a series of very efficient and hi...
This paper describes a strategy followed to achieve a sensing phenomenon in aqueous media using water-insoluble organic molecules. A sensory polymeric material for the colorimetric sensing of cyanide in water has been de...
Due to the protection of ionic liquid polymer thin film, the long-term operation stability of carbon nanotube-supported platinum nanoparticles for methanol electrooxidation has been improved.
This study proposes a novel two-step strategy to prepare single-phase unitary/binary oxides-graphene composites: precipitating hydroxides followed by microwave-assisted hydrothermal or solvothermal annealing.
A structurally simple low molecular weight hydrogelator derived from isophthalic acid forms robust pH-responsive hydrogels capable of highly efficient and selective dye adsorption.
A simple and versatile nanoscale force induced precipitation approach for the separation of gold nanoparticles (AuNPs) was developed. The AuNPs show sharp size-dependent colloidal stability thresholds as a function of sa...
Carbon nanotube sponges show effective filtration for nanoparticles and dye molecules with different sizes and concentrations from water. The three-dimensional interconnected porous structure formed by entangled nanotube...
A long-chain amidoamine derivative (C18AA) acts as a normal organogelator in toluene, but changes to a heat-induced gelator, exhibiting a phase transition from sol to gel on heating upon addition of aqueous LiCl to the t...
We report an enzymatic sensor based on an organic electrochemical transistor that uses a room temperature ionic liquid as an integral part of its structure and as an immobilization medium for the enzyme and the mediator....
Here we report the first example of a photoactivatable ribozyme which catalyzes a bimolecular reaction of two small organic molecules with multiple turnover, under control of a photo-cleavable protecting group by exploit...
Use of a closo-1,12-dicarbadecaborane backbone to link two different organic dyes separated by ca. 37 angstrom promotes exclusive through space electronic energy transfer with an efficiency of 81 to 87% with Stoke shifts...
Two Zn MOFs, MOF-645 and MOF-646, comprised of polarized 1,3-azulenedicarboxylate were synthesized. The guest free MOF-646 showed strong MOF-H-2 interactions (7.8-6.8 kJ mol(-1)), which revealed the significant impact of...
