A Novel Type of Stereoisomerism in Calix[4]arene‐Based Carceplexes

Abstract

Different orientations of the guest in the cavity of a carcerand lead to a new type of stereoisomerism, “carceroisomerism”. The structure of the host–guest compound (which is shown on the cover of this issue) and its dynamic behavior was studied in detail by NMR methods. Such compounds could perhaps find application as molecular switches for electronic devices.
