摘要: We report the isolation, characterization, and recognition behavior of iCB[6] iCB[7], which are diastereomers CB[6] CB[7], respectively, containing a single inverted glycoluril unit. Product resubmission experiments establish that these CB[n] intermediates in mechanism formation. As consequence ring, cucurbiturils possess permanent dipole moment, slightly smaller than their diastereomers, show distinctive selectivity behavior, directly on contents hydrophobic cavity.
