Boron‐Cluster Embedded Necklace‐Shaped Nanohoops

Angewandte Chemie International Edition, 2022
AbstractThe combination of carbon‐based nanohoops with other functional organic molecular structures should lead to the design of new molecular configurations with interesting properties. Here, necklace‐like nanohoops embedded with carborane were synthesized for the first time.

Dynamical behavior of boron clusters

Nanoscale, 2016
Several of the lowest energy structures of small and medium sized boron clusters are two-dimensional systems made up of a pair of concentric rings. In some cases, the barriers to the rotation of one of those rings relative to the other are remarkably low.

Identification of boron clusters and boron-interstitial clusters in silicon

Physical Review B, 2003
The identity of boron clusters and boron interstitial clusters in Si, produced by radiation or implantation, has been studied theoretically. Local vibration modes of the single-boron interstitial and the diboron split interstitial $({\mathrm{B}}_{2}\mathrm{I})$ and its metastable isomer as well as substitutional dimers are found to be in good agreement

Boron clusters-based metallodendrimers

Inorganica Chimica Acta, 2014
Abstract This review includes a compilation of different types of star-shaped molecules and dendrimers decorated with boron clusters, carboranes or metallacarboranes, at their periphery. Dendrimeric platforms, such as PAMAM, carbosilane, poly(aryl-ether), among others, have been functionalized with a different number of small metallacarboranes, nido ...

Ionic Liquids Containing Boron Cluster Anions

Inorganic Chemistry, 2009
The 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 ...

Macropolyhedral boron-containing cluster chemistry

Journal of Organometallic Chemistry, 2002
Abstract Twenty-vertex [(PPh3)4ClPd4B16H17(PPh3)] (1),1 from the thermolysis of [(PPh3)2PdB8H12] (2)1 in refluxing toluene solution, followed by CH2Cl2 extraction, has a core nido five-vertex {Pd2B3} unit that has opposing triangular faces in common with an arachno ten-vertex {Pd2B8} unit and a nido eleven-vertex {Pd3B8} unit.

Boron‐Cluster‐Enhanced Ultralong Organic Phosphorescence

Angewandte Chemie International Edition, 2019
AbstractAlthough 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

Boron Clusters in Liquid Crystals

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1995
Abstract 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.
