An Electron‐Rich Helical Host for the Exclusive Removal of a Planar Electron‐Deficient Organic Compound

In this study, a series of electron‐rich helical hosts, viz. Pyr‐HAC , Anth‐HAC and Ben‐HAC , containing pyrene, anthracene and benzene residues, respectively, at their periphery, were screened for their interaction with different planar electron‐deficient organic guests (PEDOGs). A strong and highly selective charge‐transfer interactions (CTI) was observed between the host Pyr‐HAC and the guest 1,2,4,5‐tetracyano‐benzene (TCNB), leading to a...
