Regulation of dynamic chirality and conversion of the regulated dynamic chirality to static chirality is challenging and important for their applications. In their Research Article (e202217971), Tomoki Ogoshi and co-workers report the control and amplification of dynamic planar chirality of pillar[5]arene by guest solvents and crystallization, respectively. The regulated dynamic chirality was changed to static chirality by introducing bulky stoppers. The image shows the conversion of the dynamic-to-static planar chirality in pillar[5]arenes (cars) by introducing bulky stoppers (pit stop).
