“…[13] Hemicarcerands, such as 1 shown in Figure 6, have cavities large enough to include small molecules such as CH 2 Cl 2 or (CH 3 ) 2 NCOCH 3 , but too small to include molecules such as diphenyl ether. When the inclusion complex 1·A C H T U N G T R E N N U N G (CH 3 ) 2 NCOCH 3 was dissolved in diphenyl ether and heated to 195 8C for 5 days, 1 H NMR spectroscopy showed that the small formamide guest was indeed removed to leave the empty host dissolved in the sterically hindered solvent.…”

“…The hydrogen bonds are provided by an unusual circular array of eight ureas, which "zippers" the two hemispheres together ( Fig. 1) (6)(7)(8)(9). Four of the interlocking ureas come from the top hemisphere, and four come from the bottom hemisphere.…”
