Abstract

A mono-pyrene substituted thiacalix[4]arene chemosensor (TCA-Py) was successfully synthesized in satisfactory yield. Fluorescence analysis revealed that TCA-Py exhibited a high recognition selectivity toward the Al(ClO₄)₃ molecule due to the synergy between the Al³⁺ cation and ClO₄^- anion. This unique ability to recognise an entire inorganic molecule broadens the field of molecular recognition.
