Conversion of F-BODIPYs to Cl-BODIPYs: Enhancing the Reactivity of F-BODIPYs
A new method for the synthesis of Cl-BODIPYs from F-BODIPYs is reported, merely requiring treatment of the F-BODIPY with boron trichloride. Cl-BODIPYs are exploited as synthetic intermediates generated in situ for the ... -
Decarboxylative Arylation of Substituted Pyrroles N-protected with 2-(Trimethylsilyl) ethoxymethyl (SEM)
Palladium-catalyzed decarboxylative arylation is reported using pyrroles N-protected with the 2-(trimethylsilyl) ethoxymethyl (SEM) group and featuring 2-, 3- and 4-substituents about the pyrrolic framework. In contrast ... -
Density-operator theory of orbital magnetic susceptibility in periodic insulators
The theoretical treatment of homogeneous static magnetic fields in periodic systems is challenging, as the corresponding vector potential breaks the translational invariance of the Hamiltonian. Based on density operators ... -
Designing glass with non-dispersive stress-optic response
The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ... -
Deuteration and Tautomeric Reactivity of the 1-Methyl Functionality of Free-base Dipyrrins
Regioselective reactivity of the 1-methyl group of free-base dipyrrins is explored, including discussion of tautomerism to provide exocyclic alkenyl reactivity. Deuterium is installed such as to generate dipyrrins substituted ... -
Dynamics of anions and cations in cesium hydrogensulfide (CsHS, CsDS): Neutron and x-ray diffraction, calorimetry and proton NMR investigations
Protonated and deuterated samples of the hydrogensulfide of cesium were studied by high-resolution neutron powder diffraction, calorimetry and proton NMR investigations in a wide temperature range. Primarily due to ... -
Electrochemical Activity of Nano-NiSi2 in Li Cells
Crystalline and nanocrystalline NiSi2 were studied as negative electrode materials in Li cells. Crystalline NiSi2 was found to be inactive toward lithiation/delithiation. However, it was found that NiSi2 becomes active ... -
The Electrochemical Behavior of Polyimide Binders in Li and Na Cells
The electrochemistry of aromatic and aliphatic polyimide binders was characterized in composite coatings for Li-ion and Na-ion battery negative electrodes. Aromatic polyimide was found to have a large first lithiation ...
