报道了一种新型纳米汽车的设计与合成。为了控制它们的运动，我们集成了一个偶极子，该偶极子可以通过在卟啉主链的5 -和15 -位置上的战略性供体和受体取代基进行调谐。这两个其他的中间位置被乙基三烯取代，它被称为轮子。九种纳米汽车的完整表征以及这些推拉分子的电化学。DFT计算使我们能够评估偶极子的大小，并了解电化学行为以及它如何受到电子提供和接受基团的影响。还获得了一种纳米汽车的X射线晶体结构。
The design and synthesis of a new family of nanocars is reported. To control their motion, we integrated a dipole which can be tuned thanks to strategic donor and acceptor substituents at the 5‐ and 15‐positions of the porphyrin backbone. The two othermesopositions are substituted with ethynyltriptycene moieties which are known to act as wheels. Full characterization of nine nanocars is presented as well as the electrochemistry of these push‐pull molecules. DFT calculations allowed us to evaluate the magnitude of the dipoles and to understand the electrochemical behavior and how it is affected by the electron donating and accepting groups present. An X‐ray crystal structure of one nanocar has also been obtained.
