Pyrido-21-crown-7 (P21C7) has been synthesized and shown to form [2]pseudorotaxanes spontaneously with secondary dialkylammonium ions. These complexes are stronger than their benzo-21-crown-7 counterparts and much stronger than their dibenzo-24-crown-8 counterparts. Based on this new P21C7/secondary dialkylammonium salt recognition motif, a [2]rotaxane terminated by phenyl groups as stoppers has been successfully
已合成Pyrido-21-crown-7(P21C7),并显示其与仲二烷基铵离子自发形成[2]假轮烷。这些配合物比其苯并21冠7对应物更强,并且比其二苯并24冠8对应物更强。基于此新的P21C7 /仲二烷基铵盐识别基序,已成功使用穿线接着塞技术构建了以苯基为终止基的[2]轮烷。
