Complexation Behavior of a Supramolecular Organic Fluorophore Prepared by Solid‐State Co‐Grinding Crystallization Using 2‐Anthracenecarboxylic Acid and (<i>R</i>)‐1‐(2‐Naphthyl)ethylamine and Its Optical Properties

Abstract

Abstract A novel crystalline supramolecular organic fluorophorehaving a 2 1 ‐helical columnar structure has been prepared by solid‐state co‐grinding crystallization using crystals of 2‐anthracenecarboxylic acid and ( R )‐1‐(2‐naphthyl)ethylamine. Although many organic fluorophores lose their fluorescence in the solid state, this supramolecular organic fluorophore exhibits fluorescence even in the solid state.(© Wiley‐VCH Verlag GmbH &amp; Co.
