The electronic structure of recently discovered hollow-cage molecule T&C,, has been calculated and compared to similarly shaped hypothetical molecules M8Xi2 (M=metal and X= B, C, or N). The cohesion of the cage is related to the o-bonding between M-X arising from d-sp hybridization. It is also shown that the cage can become electronically closed shell with all the valence electrons paired when ...

A modular synthesis of functionalised biaryl phenols from two boronic acid derivatives has been developed via one-pot Suzuki-Miyaura cross-coupling, chemoselective control of boron solution speciation to generate a reactive boronic ester in situ, and oxidation. The utility of this method has been further demonstrated by application in the synthesis of drug molecules and components of organic el...

The existence of two novel hybrid two-dimensional (2D) monolayers, 2D B3C2P3 and B2C4P2, has been predicted based on the density functional theory calculations. It shown that these materials possess structural thermodynamic stability. is a moderate band gap semiconductor, while B2C4P2 zero semiconductor. also highly tunable under effect strain substrate engineering. Moreover, produces low barri...

Recent scanning tunneling microscopy (STM) experiments have shown that, by dosing liquid water to the bare hexagonal boron nitride (h-BN) nanomesh on Rh(111), water dusters can be observed in the nanomesh pores. With the present work, we intend to better understand the nature of the interaction of water with the nanomesh and give indications on the type of structures that have been observed. To...

Several new synthetic methods for B-10 containing nucleoside derivatives have been developed. (1) The palladium-catalyzed coupling reaction of halogenated nucleoside derivatives with the aryltin compound having a boronic moiety proceeds chemoselectively at the C-Sn bond rather than the C-B bond to give boron-containing nucleoside derivatives. (2) The 1,2-addition reaction of the carbanions, gen...

The concept of aromaticity has been paramount significance in myriad fields chemistry. To modulate the intrinsic electronic nature aromatic molecules, partial incorporation heteroatoms into benzene scaffold represents a useful strategy modern inorganic This account presents how to incorporate boron six-membered scaffolds, leading hybrid organic/inorganic benzenes, namely diazadiborinines. In ad...

The B(9)(-) cluster was found previously to be an unprecedented molecular wheel containing an octacoordinate planar boron with D(8h) symmetry in a combined photoelectron spectroscopy (PES) and theoretical study [H. J. Zhai et al., Angew. Chem., Int. Ed. 42, 6004 (2003)]. However, the PES spectra of B(9)(-) exhibit minor features that cannot be explained by the global minimum D(8h) structure, su...

It was recently proposed that boron might be the most important nutrient structuring tree species distributions in tropical forests. Here we combine observational and experimental studies to test this hypothesis for lowland tropical forests of Panama. Plant-available boron is uniformly low in tropical forest soils of Panama and is not significantly associated with any of the > 500 species in a ...

Self-assembled monolayers of a molecular spoked wheel (a shape-persistent macrocycle with an intraannular spoke/hub system) and its synthetic precursor are investigated by scanning tunneling microscopy (STM) at the liquid/solid interface of 1-octanoic acid and highly oriented pyrolytic graphite. The submolecularly resolved STM images reveal that the molecules indeed behave as more or less rigid...
