Triazole-Modified Calix[4]crown as a Novel Fluorescent On−Off Switchable Chemosensor

A novel fluorescent on−off switchable chemosensor 1 with two different types of cationic binding sites is synthesized, which is composed of a triazole-modified calix[4]crown in the 1,3-alternate conformation. Among 15 metal ions examined, the fluorescence of 1 was strongly quenched by Hg2+, Cu2+, Cr...
