The empty pz-orbital of a three-coordinate organoboron compound leads to its electron-
deficient properties, which make it an excellent π-acceptor in conjugated organic …

Boron has one valence electron less than a carbon atom and an available vacant pz orbital.
The incorporation of sp2‐hybridized boron atoms into the host lattice of a polycyclic aromatic …

This review covers all aspects of 9-borafluorene chemistry, from the first attempted synthesis
in 1960 to the present. This class of molecules consists of a tricyclic system featuring a …

Heteroatom doping is a powerful strategy to alter the electronic structure of polycyclic
aromatic hydrocarbons (PAHs). Especially boron doping endows PAH scaffolds with …

(Hetero) arene-fused boroles are a class of compounds containing a 5-membered boron
diene-ring. Based on their molecular framework, the (hetero) arene-fused boroles can be …

Three-dimensional (3D) analogues of 9-borafluorenes,(C2B10H10) 2BR (R= Cl (1), Br (2), H
(3, merely as ether or silane adduct), phenyl (4), mesityl (5)), were synthesized and fully …

Abstract N‐Heterocyclic carbene (NHC)‐and cyclic (alkyl)(amino) carbene (CAAC)‐
stabilized borafluorene radicals have been isolated and characterized by elemental …

Abstract p–π conjugation with embedded heteroatoms offers unique opportunities to tune
the electronic structure of conjugated polymers. An approach is presented to form highly …

The choice of backbone linker for two ortho-bis-(9-borafluorene) s has a great influence on
the LUMO located at the boron centers and, therefore, the reactivity of the respective …

The reactions of 9-borafluorenes with organic azides result in either the insertion of the α-
nitrogen and elimination of N2 or the insertion of the γ-nitrogen to generate the …
