Hydride Materials for Advanced Electrochemical Energy Storage: Progress and Perspectives

EcoEnergy, EarlyView.
Hydrides are emerging as functional materials for low‐carbon electrochemical energy storage. Complex hydrides provide polyanionic electrolyte frameworks for all‐solid‐state, Li–S, and multivalent batteries; hydride ion conductors enable H− transport for emerging hydride‐based cells; and metal hydrides offer established electrode chemistries for Ni–MH ...

o‐Carborane‐based multi‐resonance thermally activated delayed fluorescence emitter exhibits highly efficient and multifunctional electroluminescence

FlexMat, EarlyView.
By strategically incorporating boron/nitrogen multi‐resonance (B/N‐MR) core into the o‐carborane unit, perfect exciton utilization can be achieved as well as exhibiting stimuli‐responsive properties. The resulting DBN‐oCb‐based organic light‐emitting diode (OLED) demonstrated an impressive external quantum efficiency of 22.3%, the highest reported for ...

Forging Unsupported Metal–Boryl Bonds with Icosahedral Carboranes [PDF]

, 2016
In contrast to the plethora of metal-catalyzed cross-coupling methods available for the installation of functional groups on aromatic hydrocarbons, a comparable variety of methods are currently not available for icosahedral carboranes, which are boron ...

Synthesis of new representatives of A3B-type carboranylporphyrins based on meso-tetra(pentafluorophenyl)porphyrin transformations

Beilstein Journal of Organic Chemistry
A carboranylporphyrin of A3B-type bearing a single pentafluorophenyl ring was prepared through the regioselective nucleophilic aromatic substitution reaction of the p-fluorine atoms in 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin with 9-mercapto-m ...

Insertion of Carbenes into Deprotonated nido-Undecaborane, B₁₁H₁₃(2-)

Molecules, 2019
We have examined the insertion of carbenes carrying leaving groups into the [nido-B11H13]2− dianion to form the [closo-1-CB11H12]− anion. The best procedure uses CF3SiMe3 and LiCl as the source of CF2.

Competition between Halogen, Hydrogen and Dihydrogen Bonding in Brominated Carboranes [PDF]

, 2016
Halogen bonds are a subset of noncovalent interactions with rapidly expanding applications in materials and medicinal chemistry. While halogen bonding is well known in organic compounds, it is new in the field of boron cluster chemistry.
