Pseudorotaxane orientational stereoisomerism driven by π-electron density.

Carmine Gaeta1, Carmen Talotta, Placido Neri.   

Abstract

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