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 ( Kave = 4.36 × 105 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 C10-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 Mn = 407 kDa. These are the first truly polymeric pseudorotaxane-type AA/BB supramolecular polymers.

来自 BISCRYPTANDS 和 BISPARAQUATS 的超分子 Pseudorotaxane 聚合物

合成了五个新的基于双（二苯并 30-冠-10 的密码体），其中两个（16 和 17）具有长（12 个原子）的柔性间隔基，导致二苄基百草枯 TFSI（Kave = 4.36 × 105 M-1 用于 17•2b)。16 和 17 与具有类似间隔物（18、21 和 23）的双百草枯的自组装导致溶液中的高分子量超分子假轮烷聚合物。从浓缩溶液中提取连续的柔性纤维。17 在二氯甲烷 (DCM) 中使用 C10 连接的双百草枯 23 产生了对数粘度对浓度曲线，极限斜率为 3.55，证实了高分子量；在 37 mM 时，聚合度估计为 126，Mn = 407 kDa。这些是第一个真正聚合的假轮烷型 AA/BB 超分子聚合物。
