Redox- and Protonation-Tunable Diboraheptacenes Acenes are attractive molecular platforms with characteristic π-electron delocalization, resulting in exceptionally small HOMO–LUMO gaps, which makes them valuable for use in a variety of organic elec...

Our manuscript on the redox- and protonation-chemistry of diboraheptacenes is published in @jacs.acspublications.org (pubs.acs.org/doi/full/10....)! @JinhyoHwang and @chemheechan report a DBH dianion (w/NIR absorption) that’s the longest fully conjugated boron-doped acene! #maingroup

From @heechankim.bsky.social @rjgilliard.bsky.social a range of boron helices @jacs.acspublications.org.

This double-stranded diborahelicate could be transformed into luminescent borahelicates and cationic boron coordination complexes.

This week's #ChemSciPicks comes from Robert J Gilliard and Christopher Cummins (Massachusetts Institute of Technology, United States).

The authors use the elimination of hexamethylbenzene to form transient boron-containing unsaturated bonds.
