Nickel complexes of phosphine-appended benzannulated boron heterocycles [PDF]

, 2019
We report the synthesis and characterization of two diphosphine nickel complexes containing 9-borafluorene (PBFlu, 9-(diisopropylphosphino)phenyl-9-borafluorene) and 9,10-dihydroboranthrene (B 2 P 2 , 9,10-bis(2-(diisopropylphosphino)phenyl)-9,10 ...

Predicted thermoelectric properties of olivine-type Fe2GeCh4 (Ch = S, Se and Te)

, 2015
We present here the thermoelectric properties of olivine-type Fe2GeCh4 (Ch = S, Se and Te) using the linear augmented plane wave method based on first principles density functional calculations.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.

Computational Investigation about the Effects of Solvent Polarity and Chalcogen Element Electronegativity on ESIPT Behaviors for the Et₂N-Substituted Flavonoid

Molecules
Inspired by the outstanding nature of flavonoid derivatives in the fields of chemistry and medicine, in this work we mainly focus on exploring the photo-induced properties of the novel Et2N-substituted flavonoid (ENF) fluorophore theoretically ...

Isolation and Structural Characterization of Se‐Hügerschoff Intermediates Derived From 4‐Bromoaniline

Journal of Heterocyclic Chemistry, EarlyView.
Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.

Ammonium Oxathioamidate

Molbank
Ammonium oxathioamidate (1) was synthesised by the reaction between O-ethyl-thioxamate (oxalic acid-1-amide-2-O-ethyl ester) and ammonium hydrogen carbonate in water solution. Compound 1 was fully characterised by both microanalytical (elemental analysis,

Plasmon–Exciton–Driven Modulation of the Electronic and Optical Properties of MoS2 via Cayley Tree Fractal Nanostructures

Journal of Raman Spectroscopy, EarlyView.
This work investigates the change in optical and electronic properties of monolayer MoS2 through the coupling of its excitons and a plasmonic fractal structure. The formation of the heterostructure shows significant enhancement on the edge of the fractal pattern relative to off, owing to the enhanced electric field at the edge of the branches.

Covalent Nitrogen Doping and Compressive Strain in MoS2 by Remote N2 Plasma Exposure

, 2016
Controllable doping of two-dimensional materials is highly desired for ideal device performance in both hetero- and p-n homo-junctions. Herein, we propose an effective strategy for doping of MoS2 with nitrogen through a remote N2 plasma surface treatment.
