An anthracene-appended 2:3 copillar[5]arene: synthesis, computational studies, and application in highly selective fluorescence sensing for Fe(III) ions.

Herein an anthracene-appended 2:3 copillar[5]arene was prepared by the CuAAC method, which was further used as a Fe(3+)-selective fluorescent chemosensor over a wide range of metal ions.
