Pseudo[2]rotaxane orientational isomers were formed in a stereocontrolled way by exploiting the electron-withdrawing (EW) or electrondonating (ED) effects of para-substituted dibenzylammonium axles threaded through the p-electron rich calixarene cavity, which allow the fine tuning of the weak p–p interactions.

Abstract
Pseudo[2]rotaxane orientational isomers were formed in a stereocontrolled way by exploiting the electron-withdrawing (EW) or electrondonating (ED) effects of para-substituted dibenzylammonium axles threaded through the p-electron rich calixarene cavity, which allow the fine tuning of the weak p–p interactions.File in questo prodotto:
