Supramolecular metallacycles with a 'pseudo double-paracyclophane' structure based on flexible π-conjugated linkers
Abstract
The straightforward synthesis of new supramolecular metallacycles having a 'pseudo double-paracyclophane' structure is presented. They are obtained from the reaction of a pre-assembled Cu(i) bimetallic precursor bearing short intermetallic distances with cyano-capped homoditopic π-conjugated linkers having flexible central cores.
