A borane laser [PDF]

Nature Communications, 2015
Emission from electronically excited species forms the basis for an important class of light sources-lasers. So far, commercially available solution-processed blue-emitting laser materials are based on organic compounds or semiconductor nanocrystals that have significant limitations: either low solubility, low chemical- and/or photo-stability and/or ...

Catalytic Dehydrogenation of Amine‐Boranes using Geminal Phosphino‐Boranes [PDF]

Zeitschrift für anorganische und allgemeine Chemie, 2020
The reaction of the intramolecular frustrated Lewis pair (FLP) tBu2PCH2BPh2 with the amine‐boranes NH3·BH3 and Me2NH·BH3 leads to the formation of the corresponding FLP‐H2 adducts as well as novel five‐membered heterocycles that result from capturing the in situ formed amino‐borane by a second equivalent of FLP.
