In the search for innovative new light sources, the discovery that solutions of the boron hydride anti-B18H22 generate photostable blue laser emission stands out in its significance as the first laser borane. Surprisingly, though, the laser performance...

The dimetallic boron hydride cluster, (PMe2Ph)4Pt2B10H10 (1-Pt2), is known to reversibly sequester small molecules (e.g., O2, CO, and SO2) across its Pt–Pt cluster vector. Here, we report the very different effect of the addition of nitric oxide (NO) to solutions of...

Methylation of anti-B18H22 (1) affords the first example of alkyl substitution of terminal hydrogen atoms on the fluorescent octadecaborane-22 molecule to give highly methylated 2,2′-Cl2-1,1′,3,3′,4,4′,7,7′,8,8′,10,10′-Me12-anti-B18H8 (2). This extensive chemical...

The reaction of K[arachno-B9H14] with [NiCl2(dppe)] produces four new 19-vertex macropolyhedral metallaboranes that result from borane cluster fusion: [9′-(dppe)-9′-Ni-anti-B18H20] (1) and isomeric [11′-(dppe)-11′-Ni-syn-B18H20] (2), together with the...

The latest contribution to our growing portfolio of usefully luminescent boranes. In this paper we describe the effect of iodination on the luminescence from the laser borane anti-B18H22. Our high-yield synthetic methods provide new highly phosphorescent species that...

Decaborane(14), nido-B10H14, is the major commercially available molecular building block in boron cluster chemistry. The condensation of two such {nido-B10} blocks gives the known isomers of B18H22 – a molecule used in the fabrication of p-type semiconductors and...
