Far?Red and Near?Infrared Boron Schiff Bases (BOSCHIBAs) Dyes Bearing Anionic Boron Clusters

Boron Sheets and Boron Nanotubes

Based on an ab initio study, we present a structure model for a broad boron sheet, which is the precursor of boron nanotubes. Furthermore we could show that, in contrast to the armchair types, zigzag boron nanotubes have no surface tension (strain energy). As result, we predict that boron nanotubes will exhibit a chirality dependent stability, something that is unique among all nanotubular mate...

Functionalizing graphene by embedded boron clusters.

We present a model system that might serve as a blueprint for the controlled layout of graphene based nanodevices. The systems consists of chains of B(7) clusters implanted in a graphene matrix, where the boron clusters are not directly connected. We show that the graphene matrix easily accepts these alternating B(7)-C(6) chains and that the implanted boron components may dramatically modify th...

Boron-pyridyl-imino-isoindoline dyes: facile synthesis and photophysical properties.

The synthesis of boron-pyridyl-imino-isoindoline dyes, a novel type of BODIPY analogue, involves a facile and scalable two-step reaction. Broad envelopes of intense vibrational bands are observed for the main spectral bands in the absorption and emission spectra. High fluorescence quantum yields are obtained in solution, with significant intensity also observed in the solid-state.

Atomic and electronic structures of neutral and charged boron and boron-rich clusters

The first anionic four-connected boron imidazolate framework.

Reported here is an organic-cation templated 4-connected anionic boron imidazolate framework [N(CH(3))(4)][Cd(SH)(2)B(im)(4)] (ABIF-1, im = imidazolyl), which is synthesized from the reaction of the supertetrahedral Cd(10)S(4)(SPh)(12) cluster with [N(CH(3))(4)]Cl and NaB(im)(4). The work represents an important step in the expansion of boron imidazolate frameworks from neutral BIFs to anionic ...
