Xiaoyong Lu - Kinetic vs Thermodynamic Self-Sorting of Cucurbit[6]uril, Cucurbit[7]uril, and a Spermine Derivative

Version 1

      Publication Details (including relevant citation   information):

      Cucurbit[6]-, cucurbit[7]-, and cucurbit[6]uril cavitands can be   aligned  along a spermine derivative axle in a well-defined,   kinetically favored  sequence at room temperature, and can   undergo a reorganization toward a  more stable   [4]pseudorotaxane bearing three cucurbit[6]uril units upon    thermally induced scrambling.
