| Abstract: | Fluorogenic tert-butylcalix[4]arenes bearing two pyrene pendant groups at the lower rim were synthesized. Based on ratiometric changes of monomer and excimer emissions, the pyrene amine derivative of calix[4]arene has been found to act as a selective sensor for Pb2+ and Cu2+ ions, respectively, due to a conformational change upon chelation of these ions. |
