A highly electron-deficient dicyanomethylene-bridged triarylborane,FMesB-TCN, was reported with a low-lying LUMO and crystallization-induced emission enhancement in its block-shape crystal. DFT calculations revealed lower re-organization energy

, p. 9761 - 9765,5 (2014)
Introduced herein is a series of conjugated thienylboranes, which are inert to air and moisture, and even resist acids and strong bases. X-ray analyses reveal a coplanar arrangement of the thiophene rings, an arrangement which facilitates p-π conjugation

A series of dicyanomethylene-functionalized triarylboranes is reported in this work, with low-lying LUMO energy levels at ca. -3.66 eV for FMesB-ACN. The single-crystal structures of the mono- and dianion of Mes*B-ACN were obtained via chemical reduction,

We introduce a new boron-doped cyclophane, the hexabora[16]cyclophane B6-FMes, in which six tricoordinate borane moieties alternate with short conjugated p-phenylene linkers. Exocyclic 2,4,6-tris(trifluoromethyl)phenyl (FM
Synthesis and characterisation of some new boron compounds containing the 2,4,6-(CF3)3C6 H2 (fluoromes = Ar), 2,6-(CF3)2C6H3 (fluoroxyl = Ar′), or 2,4-(CF3)2 C6H3 (Ar″) ligands

Several new boron compounds containing the 2,4,6- (CF3)3C6H2 (fluoromes = Ar), 2,6-(CF3)2C6H3 (fluoroxyl = Ar′) or 2,4-(CF3)2C6H3 (Ar″) ligands have been synthesised from reactions of ArLi, Ar′Li or Ar″Li with BCl3, and characterised by 19F and 11B NMR spectroscopy. Chlorine/fluorine exchanges are evident in these reactions. The crystal and molecular structures of Ar2BF, Ar″3B, Ar2B(OH), Ar′B(OH)2 and Mes2BF (Mes = 2,4,6-Me3C6H2) have been determined by single crystal X-ray diffraction. Ar″3B represents the first example of a compound containing three Ar″ ligands to be structurally characterised. Molecular geometries and GIAO-NMR shifts for several new boron compounds have been calculated at the HF/6-31G* level of theory, and compared with the available experimental results.
New Aspects of the Chemistry of 2,4,6-Tris(trifluoromethyl) Benzoic Acid and Related Compounds
