Metal-Free Reduction of Phosphine Oxides Using Polymethylhydrosiloxane
Inorganics, 2016 A simple protocol is presented here for the use of inexpensive polymethylhydrosiloxane (PMHS), a waste product of the silicon industry, as stoichiometric reducing agent for phosphine oxides to phosphines, a highly desirable reaction to recover P-based ...

Advanced Optical Materials, EarlyView.A surface passivation strategy using yttrium acetate to suppress Mg ion migration from the ZnMgO electron transport layer is proposed. This treatment restores oxygen vacancies on the ZnMgO surface, enhancing device stability. The Cd‐free quantum dot light‐emitting diodes demonstrate a 65.5% increase in operational lifetime with an external quantum ...

Can low-valent silicon compounds be better transition metal ligands than phosphines and NHCs?
, 2015 We investigated the potential application of experimentally characterized low-valent silicon compounds as transition metal ligands by computing the most important ligand properties, σ-donor and π-acceptor ability, ligand-to-metal charge transfer, and ...

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Advanced Photonics Research, EarlyView.Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Advanced Synthesis &Catalysis, EarlyView.Abstract Pd‐catalyzed reactions are among the most straightforward and efficient methods to proficiently build Csp2‐Csp2 bonds. Nevertheless, thermal activation remains mandatory in most cases, which may decrease the compatibility with sensitive functional groups.
