Cation-Driven Self-Assembly of a Gold(I)-Based Metallo-Tweezer

Abstract

A combination of self-complementary π–π-stacking interactions and metallophilic interactions triggered the self-assembly of a new digold(I) metallo-tweezer in the presence of several types of M+ ions. Titrations by fluorescence spectroscopy enabled the determination of the association constants of the resulting inclusion duplex complexes.
