• Analysis and Improvement of an Anion-Templated Rotaxane Synthesis
  作者：Christoph A. Schalley、Gabriele Silva、Carl Friedrich Nising、Petra Linnartz

  DOI：10.1002/1522-2675(200206)85:6<1578::aid-hlca1578>3.0.co;2-l

  日期：2002.6

  A series of new rotaxanes with axles different in length was prepared. Following the synthetic protocol utilizing a known anion template effect (Scheme 1), surprisingly low yields in the order of 2 - 5% were obtained (Scheme 3), which furthermore significantly depended on the nature of the stopper (Fig. 1). Variations in the synthetic procedures and computational results from Monte Carlo simulations allowed us to analyze the origin of these findings: The rotaxane wheel 3 acts as a noncovalently bound 'protecting group' for the stopper nucleophile. The protection of the nucleophilic phenolate O-atom depends much on the steric demands of the stoppers (see 2 vs. 10) which induce different conformations of the wheel. Based on this model. an improved synthetic scheme is suggested.
• Supramolecular Pseudorotaxane Polymers from Biscryptands and Bisparaquats

  DOI：10.1021/jacs.8b01480

  日期：2018.3.28

  Five new bis(dibenzo-30-crown-10-based cryptand)s were synthesized, two of which (16 and 17) had long (12-atom), flexible spacers that led to cooperative complexation of dibenzyl paraquat TFSI (K-ave = 4.36 X 10(5) M-1 for 17.2b). Self-assembly of 16 and 17 with bisparaquats with similar spacers (18, 21, and 23) led to high molecular weight supramolecular pseudorotaxane polymers in solution. Continuous, flexible fibers were drawn from concentrated solutions. 17 with C-10-linked bisparaquat 23 in dichloromethane (DCM) produced a log-log viscosity vs concentration plot with a limiting slope of 3.55, confirming high molecular weight; at 37 mM, the degree of polymerization was estimated to be 126 and M-n = 407 kDa. These are the first truly polymeric pseudorotaxane-type AA/BB supramolecular polymers.
