Strong exciton coupling and circularly polarised luminescence in rigid complexes of chiral macrocyclic tetranaphthylamides

Abstract

Strong exciton coupling occurs between adjacent pairs of naphthyl chromophores in the chiral sodium and europium complexes of L¹; in the constitutionally isomeric complexes of L², intramolecular excimer formation is observed and both sets of Eu complexes give a well defined, metal-based circularly polarised emission.
