The pentiptycene receptors form edge-to-face complexes with a variety of aromatic guests including nitroaromatics. X-ray diffractometry revealed that compounds 1, 2, and 3 form host-guest assemblies with a thienyl fragment (from a neightboring molecule of 1), benzene and nitrobenzene, respectively. X-ray studies of the three crystal structures reported here strongly suggest the edge-to-face to be a predominant binding mode between the aromatic guests and electron-rich faces of the pentiptycene aromatic cavity.
