%X Two
new twisted cucurbiturils, cucurbit[13]uril (tQ[13])
and cucurbit[15]uril (tQ[15]), have been
synthesized and separated, and their structures have been confirmed
by NMR spectroscopy and MALDI-TOF mass spectrometry together with
the X-ray structures of two new complexes, {Dy(H2O)4Cd(H2O)4tQ[13]}·2.5[CdCl4]·65H2O and {Cd0.5(H2O)2tQ[15]}·[CdCl4]·47H2O. tQ[15] is the largest cucurbit[n]uril (Q[n]) in the Q[n] family reported to date. The X-ray diffraction studies of both
complexes indicated that these large tQ[n]s effectively exhibit two different cavities–a central cavity
and two side cavities. Preliminary host–guest behavior by each
of the new systems was investigated by NMR studies.
