Highly selective recognition of the Al(ClO4)3 molecule by a mono-pyrene substituted thiacalix[4]arene chemosensor†
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.
