Developing simple boranes as phase transfer catalysts for nucleophilic fluorination using CsF [PDF]
, 2021 Despite the general high fluorophilicity of boron, simple organoboranes such as BEt3 and 3,5-(CF3)2C6H3–BPin are shown herein for the first time, to our knowledge, to be effective phase-transfer catalysts for the fluorination of organohalides with CsF ...

MATERIALS FOR FLUORINE GENERATOR ANODE ASSEMBLIES [PDF]
, 1956 Corrosion of anode assembly materials in fluorine generators is pronounced, therefore, selection of the proper materials for construction is important. Several metals and alloys have been tested for corrosion resistance when anodic in a fluorine test cell. In general, copper, copper alloys and magnesium alloys offer the best corrosion resistance.

Advanced Functional Materials, EarlyView.OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...
