TL;DR: The observation of an all-boron fullerene-like cage cluster at B40(-) with an extremely low electron-binding energy is reported, by photoelectron spectroscopy, and theoretical calculations show that this arises from a cage structure with a large energy gap, but that a quasi-planar isomer of B40 (-) with two adjacent hexagonal holes is slightly more stable than the fullerenes structure.

TL;DR: It is shown experimentally and theoretically that B36 is a highly stable quasiplanar boron cluster with a central hexagonal hole, providing the first experimental evidence that single-atom layerboron sheets with hexagonal vacancies are potentially viable.

TL;DR: A brief and timely overview is presented addressing the recent progress made on boron clusters and the approaches used in the authors' laboratories to determine the structure, stability, and chemical bonding of size-selected borons clusters by joint photoelectron spectroscopy and theoretical studies.

TL;DR: B(22)(-) and B(23)(-), the largest negatively charged boron clusters that have been characterized experimentally to date, can be viewed as all-boron analogues of anthracene and phenanthrene, respectively.

TL;DR: The metal-doped B rings are established firmly as a new class of novel aromatic molecular wheels for transition-metal-centered nine-atom boron rings by chemical bonding analyses.
