Triple-stranded triptycene-based metallo-supramolecular helicate displaying efficient encapsulation of bulky guest molecules

Triple-stranded metallo-supramolecular helicates were readily constructed by achieving a coordination of the gallium(iii) cation by ligands based on 2,7- and 2,6-disubstituted triptycenes. The significance of these building blocks in the construction of helicates with the capability for guest encaps...

Summary:Triple-stranded metallo-supramolecular helicates were readily constructed by achieving a coordination of the gallium(iii) cation by ligands based on 2,7- and 2,6-disubstituted triptycenes. The significance of these building blocks in the construction of helicates with the capability for guest encapsulation was also revealed. A triple-stranded metallo-supramolecular helicate based on 2,7-disubstituted triptycene was easily constructed, and shows efficient encapsulation of quaternary ammonium guests.
