Abstract

original image

On the flipside: A planar chiral pseudo- [1]catenane based on pillar[5]arene, in which an alkyl chain is connected to one pillar[5]arene unit, has been synthesized. Capture and release of achiral guests and solvents trigger the inclusion and de-threading of the alkyl chain, which causes the inversion of planar chirality.
