Advanced Science, EarlyView.We report a palladium‐catalyzed atroposelective cyclization of N‐heterobiaryl triflates with alkynyl boronates to access seven‐membered 1,2‐BN‐bridged biaryls with high yields and excellent enantioselectivity via a cascade DyKAT, cis‐carbopalladation, and 1,2‐migration, which expands the toolbox for axially chiral π‐conjugated boron compounds and opens

Ultra‐Thin and Highly Insulating Aromatic Monolayers by N‐Heterocyclic Carbenes
Angewandte Chemie, EarlyView.By using N‐heterocyclic carbenes extremally insulating and at the same time as thin as 0.3 nm molecular films are formed. The charge transport calculations indicate absence of destructive quantum interference effect which was so far the only way to suppress conductivity in aromatic molecules.

Advanced Science, EarlyView.Open‐shell type radical anions with stable doublet emission have been synthesized that feature aromaticity engineering, through‐space charge‐transfer (TSCT), and electro(fluoro)chromism. ABSTRACT We report the doublet emissive open‐shell radical anions, where the N‐annulated perylene diimide (PDIN–H) is functionalized with aromatic rings.

Exploration of Mechanochemical Activation in Solid-State Fluoro-Grignard Reactions
Molecules, 2020 Owing to the strength of the C−F bond, the ‘direct’ preparation of Grignard reagents, i.e., the interaction of elemental magnesium with an organic halide, typically in an ethereal solvent, fails for bulk magnesium and organofluorine ...

Aging and Electrical Stability of DNTT Honey‐Gated OFETs
Advanced Electronic Materials, EarlyView.DNTT honey‐gated organic transistors were fabricated and evaluated to assess short‐ and long‐term stability under electrical stress and aging. Short‐term transfer measurements (five days, 40 sweeps/day) showed minimal parameter shift, while extended measurements revealed gradual degradation over weeks.
