Coaxial assembly of helical aromatic foldamers by metal coordination

Abstract

Deprotonation of acid-terminated helical aromatic foldamers with a mineral base in chlorinated solvents led to their dimerization through the coordination of a metal cation (Li+, Na+, K+, Ag+, or Hg2+) with the terminal carboxylate functions. This new ligation method was applied to oligomerize diacid-functionalized foldamers.
