Terminal Titanyl Complexes of Tri- and Tetrametaphosphate: Synthesis, Structures, and Reactivity with Hydrogen Peroxide
(American Chemical Society, 2017-02)
The synthesis and characterization of tri- and tetrametaphosphate titanium(IV) oxo and peroxo complexes is described. Addition of 0.5 equiv of [OTi(acac)[subscript 2]][subscript 2] to dihydrogen tetrametaphosphate ([P[subscript ...
Frequency-Swept Integrated Solid Effect
(Wiley-Blackwell, 2017-06)
The efficiency of continuous wave dynamic nuclear polarization (DNP) experiments decreases at the high magnetic fields used in contemporary high-resolution NMR applications. To recover the expected signal enhancements from ...
Chain-Growth Polymerization of 2-Chlorothiophenes Promoted by Lewis Acids
(American Chemical Society (ACS), 2012-11)
Lewis acids promote the polymerization of several 2-chloroalkylenedioxythiophenes, providing high-molecular-weight conjugated polymers. The proposed mechanism is a cationic chain-growth polymerization, as confirmed by ...
Direct observation of ground-state lactam-lactim tautomerization using temperature-jump transient 2D IR spectroscopy
(National Academy of Sciences (U.S.), 2013-05)
We provide a systematic characterization of the nanosecond ground-state lactam-lactim tautomerization of pyridine derivatives in aqueous solution under ambient conditions using temperature-jump transient 2D IR spectroscopy. ...
Crystal structure of [4-(2-methoxyphenyl)-3-methyl-1-phenyl-6-trifluoromethyl-1H-pyrazolo[3,4-b]pyridin-5-yl](thiophen-2-yl)methanone
(International Union of Crystallography (IUCr), 2014-08)
The title compound, C[subscript 26]H[subscript 18]F[subscript 3]N[subscript 3]O[subscript 2]S, a 2-methoxy-substituted derivative, is closely related to its 4-methyl- and 4-chloro-substituted analogues and yet displays ...
Energy transfer of CdSe/ZnS nanocrystals encapsulated with rhodamine-dye functionalized poly(acrylic acid)
(2012-08)
Energy transfer between a CdSe/ZnS nanocrystal (NC) donor and a rhodamine isothiocyanate (RITC) acceptor has been achieved via a functionalized poly(acrylic acid) (PAA) encapsulating layer over the surface of the NC. The ...
Förster resonance energy transfer, absorption and emission spectra in multichromophoric systems. II. Hybrid cumulant expansion
(American Institute of Physics (AIP), 2015-03)
We develop a hybrid cumulant expansion method to account for the system-bath entanglement in the emission spectrum in the multi-chromophoric Förster transfer rate. In traditional perturbative treatments, the emission ...
Mild Palladium-Catalyzed Cyanation of (Hetero)aryl Halides and Triflates in Aqueous Media
(American Chemical Society (ACS), 2015-01)
A mild, efficient, and low-temperature palladium-catalyzed cyanation of (hetero)aryl halides and triflates is reported. Previous palladium-catalyzed cyanations of (hetero)aryl halides have required higher temperatures to ...
A Rapid and Efficient Luminescence-based Method for Assaying Phosphoglycosyltransferase Enzymes
(Nature Publishing Group, 2016-09)
Phosphoglycosyltransferases (PGTs) are families of integral membrane proteins with intriguingly diverse architectures. These enzymes function to initiate many important biosynthetic pathways including those leading to ...
Investigating Effects of Proteasome Inhibitor on Multiple Myeloma Cells Using Confocal Raman Microscopy
(MDPI AG, 2016-12)
Due to its label-free and non-destructive nature, applications of Raman spectroscopic imaging in monitoring therapeutic responses at the cellular level are growing. We have recently developed a high-speed confocal Raman ...
