Solid-State circularly polarized luminescence of chiral supramolecular organic fluorophore

Abstract

Chiral supramolecular organic fluorophores were successfully developed using two organic components with different functionalities (namely, a chiral amine and an achiral fluorescent carboxylic acid (or sulfonic acid) or an achiral amine and achiral fluorescent carboxylic acid). The supramolecular organic fluorophores exhibited chiroptical properties in the solid state, as determined by circular dichroism (CD) or circularly polarized luminescence (CPL). The chiroptical properties could easily be tuned by changing the component molecules, without the need for synthetic modifications.
