two new molecular turnstiles based on Sn–porphyrin derivatives are described. The system is composed of a stator (5‐(4‐pyridyl)‐10,15,20‐triphenylporphyrin), a hinge (SnIV) and a rotor (handle equipped with 2,6‐pyridinedicarboxamide as a tridentate coordinating site or its PdII complex). The presence of interaction sites, both on the stator and the rotor, offers the possibility of switching between
描述了两种基于Sn-卟啉衍生物的新型分子旋转栅的设计,合成和结构表征。该系统由一个定子(5-(4-吡啶基)-10,15,20-三苯基卟啉),一个铰链(Sn IV)和一个转子(装有2,6-吡啶二甲酰胺作为三齿配位位点的转子)组成。 Pd II复合物)。通过在定子和转子上都存在氢键,可以在定子和转子上都存在相互作用位点,从而可以在打开状态(手柄绕卟啉自由旋转)和闭合状态(旋转受阻)之间切换。定子和转子,或者通过两个配位基团同时结合钯。
