Selective Formation and Optical Property of a 2₁-Helical Columnar Fluorophore Composed of Achiral 2-Anthracenecarboxylic Acid and Benzylamine

Abstract

By using achiral fluorescent 2-anthracenecarboxylic acid with achiral benzylamine, a chiral 21-helical columnar organic fluorophore having circularly polarized luminescence (CPL) in the solid state is created. Although this system exhibits polymorphism, the polymorphism can be controlled by changing the crystallization method.
