Symmetrical clusters of carbon and boron
Chemical Physics Letters, 1993Abstract Some symmetrical clusters of carbon and boron are discussed by introducing the new concept of conjugate polyhedra; we obtain the results that if a polyhedron of carbon (boron) is given, its conjugate polyhedron of boron (carbon) can be obtained by interchange of n and f with l being kept constant, and that conjugate polyhedra have the ...

Boron Clusters in Liquid Crystals
Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1995Abstract 3-Dimensional aromatic moiety was used for the first time in the synthesis of liquid crystals. Several of the prepared compounds, based on σ- aromatic boron clusters 1 and 2, show only nematic mesophases with relatively high Ti, good electrochemical but limited thermal stability.

Thermochemistry and Electronic Structure of Small Boron and Boron Oxide Clusters and Their Anions
The Journal of Physical Chemistry A, 2009Thermochemical properties of a set of small boron (B(n)) and boron oxide (B(n)O(m)) clusters, with n = 1-4 and m = 0-3, their anions, and the B(4)(2-) dianion, were calculated by using coupled-cluster theory CCSD(T) calculations with the aug-cc-pVnZ (n = D, T, Q, 5) basis sets extrapolated to the complete basis set limit with additional corrections ...

Nanotubes of Boron Nitride Filled with Molybdenum Clusters
Journal of Nanoscience and Nanotechnology, 2001Carbon nanotubes are known to be metallic or semiconducting, depending on their helicity and diameter. However, boron nitride (BN) nanotubes are the only nanotubular product known to date that are predicted to have stable insulating properties that are independent of their atomic structure and morphology. Thus, the BN tube has attracted prime attention

Nucleoside Modification with Boron Clusters and Their Metal Complexes
Current Protocols in Nucleic Acid Chemistry, 2009AbstractGeneral methods for the synthesis of nucleosides modified with borane clusters and metallacarborane complexes are presented. These include: (1) the click chemistry approach based on Huisgen 1,3‐dipolar cycloaddition and (2) tethering of the metallacarborane group to the aglycone of a nucleoside via a dioxane ring opening in oxonium ...

Ionic Liquids Containing Boron Cluster Anions
Inorganic Chemistry, 2009The combination of different boron cluster anions and some of the cations typically found in the composition of ionic liquids has been possible by straightforward metathetic reactions, producing new low melting point salts; the imidazolium cations have been systematically studied, [C(n)mim]+ (when [C(n)mim]+ = 1-alkyl-3-methylimidazolium; n = 2, 4, 6 ...

Boron‐Cluster‐Enhanced Ultralong Organic Phosphorescence
Angewandte Chemie International Edition, 2019AbstractAlthough carborane‐based luminescent materials have been studied for years, no persistent phosphor has been reported so far. Herein, we describe boron‐cluster‐based persistent phosphors obtained by linking a σ‐aromatic carboranyl cage to the π system of a carbazolyl group. The carboranes were found to promote intersystem crossing from a singlet
