Vinyl-group-substituted, α-cyclodextrin-based, size-complementary [3]rotaxanes were synthesized as crosslinkers for rotaxane-crosslinked poly(methyl methacrylate) (RCP) by radical polymerization. The size complementarity of the crosslinkers made it possible to de-crosslink the RCP by heating, and the degree of decoupling was monitored by fluorescence intensity, depending on the state of the axle component of the rotaxane crosslink moiety.
乙烯基取代的、基于α-环糊精的尺寸互补[3]轮烷被合成为用于通过自由基聚合制备轮烷交联聚甲基丙烯酸甲酯(RCP)的交联剂。交联剂的尺寸互补性使得通过加热使RCP去交联成为可能,并且去偶联程度通过荧光强度进行监测,这取决于轮烷交联部分的轴组分的状态。
