Nido-carborane encapsulated by BODIPY zwitterionic polymers: Synthesis, photophysical properties and cell imaging

Journal of Saudi Chemical Society, 2021
Carborane encapsulation was visualized by using fluoroboropyrrole (BODIPY) zwitterionic polymer as fluorescence marker. Firstly, a water-soluble fluorescent probe carrier was prepared by combining the BODIPY derivatives with poly (carboxybetaine ...

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

Synthesis of Zwitter-Ionic Conjugate of Nido-Carborane with Cholesterol

Molecules, 2021
9-HC≡CCH2Me2N-nido-7,8-C2B9H11, a previously described carboranyl terminal alkyne, was used for the copper(I)-catalyzed azide-alkyne cycloaddition with azido-3β-cholesterol to form a novel zwitter-ionic conjugate of nido-carborane with cholesterol ...

Single‐Atom Control of Aromaticity and Excited‐State Dynamics in Endohedral Zirconium–Antimony Zintl Clusters

Angewandte Chemie, EarlyView.
Single‐atom growth from [Zr@Sb12]2− to [Zr@Sb13]3− disrupts the closed‐shell S2P6 superatomic configuration and markedly attenuates three‐dimensional (3D) aromaticity. Ultrafast spectroscopy further links stronger spherical aromaticity to slower excited‐state relaxation, establishing an atom‐resolved structure‐aromaticity‐dynamics relationship ...

Synthesis of B-Substituted Anthracenyl and Pyrenyl Derivatives of ortho-Carborane

Inorganics
Isomeric B-substituted anthracenyl and pyrenyl derivatives of ortho-carborane containing polycyclic aromatic substituents both in the position of the carborane cage most distant from the carbon atoms (position 9) and in the neighboring position (position

Crystal structure of 1-butyl-2,3-dimethylimidazolium dicarba-7,8-nido-undecaborate

Acta Crystallographica Section E: Crystallographic Communications, 2015
In the title molecular salt, C9H17N2+·C2H12B9−, the carborane cage has a bridging B—H—B bond on the open B3C2 face. The butyl side chain of the cation adopts an extended conformation [C—C—C—C = 179.6 (1)°].

Carborane Nanomembranes

ACS Nano
We report on the fabrication of a boron-based two-dimensional (2D) material via electron irradiation-induced cross-linking of carborane self-assembled monolayers (SAMs) on crystalline silver substrates. The SAMs of 1,2-dicarba-closo-dodecarborane-9,12-dithiol (O9,12) were prepared on flat crystalline silver substrates and irradiated with low-energy ...
