Hexaphenylbenzenes as potential acetylene sponges.
Acetylene sponges can be created by taking advantage of the nonplanar geometry of hexaphenylbenzenes and the special capacity of the central aromatic ring to engage in C(sp)-H...pi interactions reinforced by secondary C(sp(2))-H...pi interactions, as revealed by X-ray crystallographic studies and DFT calculations.
