Rhodium-catalyzed carbonylative arylation of alkynes with arylboronic acids: An efficient and straightforward method in the synthesis of 5-aryl-2(5H)-furanones
(Royal Society of Chemistry, 2006)
5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere.
Controlled Formation of the Two-Dimensional TTBC J-Aggregates in an Aqueous Solution
(American Chemical Society, 2013-09-30)
Strong experimental and theoretical evidence was provided on the controlled formation of the two-dimensional J-aggregates that were assembled in the herringbone morphology. The exciton-band structure formation of ...
Chitosan-immobilized pumice for the removal of As(V) from waters
A novel sorbent, chitosan-immobilized pumice, has been prepared for the sorption of As(V) from waters prior to its determination by hydride generation atomic absorption spectrometry. The success of the immobilization has ...
Speciation and preconcentration of inorganic tellurium from waters using a mercaptosilica microcolumn and determination by hydride generation atomic absorption spectrometry
(Royal Society of Chemistry, 2000-11-23)
A separation–preconcentration method utilising a mercapto-modified silica microcolumn was developed for the determination of trace amounts of Te(IV) and Te(VI) in waters by hydride generation atomic absorption spectrometry. ...
Optical transition rates of a meso-substituted thiacarbocyanine in methanol-in-oil reverse micelles
We report the photophysical properties of 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in methanol-in-oil (m/o) reverse micellar systems which form methanol droplets stabilized with anionic surfactant aerosol-OT ...
A BODIPY-based reactive probe for the detection of Au(iii) species and its application to cell imaging
(Royal Society of Chemistry, 2014-06)
A BODIPY-based fluorescent probe bearing a pyridyl hydrazone motif responds selectively to Au(III) ions through an irreversible C[double bond, length as m-dash]N bond hydrolysis reaction. Gold species, besides their ...
Regio- and stereoselective synthesis of 2,3,5-trienoates by palladium-catalyzed alkoxycarbonylation of conjugated enyne carbonates
(American Chemical Society, 2014-10)
Palladium-catalyzed carbonylation of 2,4-enyne carbonates in an alcohol and under balloon pressure of CO proceeds through 1,5-substitution to yield (E)-2,3,5-trienoates. The olefin geometry of the substrate is important ...
A guanidinium modified rhodamine-based fluorescent probe for in vitro/vivo imaging of gold ions
(Royal Society of Chemistry, 2015-10-07)
We devised a rhodamine-based fluorescent probe functionalized with a guanidinium moiety, which both operates efficiently in pure aqueous media and displays a selective fluorescence response to Au3+ ions. We also demonstrated ...
Novel trimodal MALDI imaging mass spectrometry (IMS3) at 10 μm reveals spatial lipid and peptide correlates implicated in Aβ plaque pathology in alzheimer's disease
(American Chemical Society, 2017-12)
Multimodal chemical imaging using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) can provide comprehensive molecular information in situ within the same tissue sections. This is of relevance for ...
Integration of triboluminescent EuD4TEA crystals to transparent polymers: Impact sensor application
(American Chemical Society, 2017-02)
Lanthanide-based organometallic materials are well-known candidate triboluminescent (TL) materials that can show bright emission when a mechanical force is applied. These materials are usually in the form of crystalline ...
