A New Role for Bboron in Advanced Materials
Published online by Cambridge University Press: 15 February 2011
Abstract
Application of highly polar dative bonds of heteroatoms to boron atoms for the preparation of a new class of liquid crystals is discussed. Semiempirical calculations show that compounds incorporating polar bonds of tetra- and higher-coordinated boron centers are characterized by large coaxial dipole moments and relatively large first hyperpolarizabilities β. It is expected that these new liquid crystalline materials will be useful for electrooptical applications.

7. The failure can be attributed to incompatibility of symmetry and energy of MO's of the σ-and π-aromatic components. It was shown that carboranes as substituents in aromatic compounds have a small or negligible resonance effect, but quite a large electron withdrawing inductive effect.Google Scholar
