Self-Assembly of Grid and Helical Hydrogen-Bonded Arrays Incorporating Bowl-Shaped Receptor Sites That Bind Globular Molecules

Self-assembly of 1,2-dicarbadodecaborane(12) (o-carborane) and bowl-shaped cyclotriveratrylene (CTV) through bifurcated C–Hcarborane⋅⋅⋅O hydrogen bonds gives infinite arrays with 2D hexagonal grid or helical chain topologies. The in-built shape-specific receptor sites bind o-carborane in (o-carborane)2(CTV) or fullerene C70 in (C70)(o-carborane)(CTV)(1,2-dichlorobenzene) shown here.
