Abstract
New fluorescent chemosensor 1 with two amidoanthraquinone groups (1-AAQs) at the lower rim of p-tert-butylcalix[4]arene has been synthesized. The significant changes of absorption and fluorescence bands show that chemosensor 1 is selective toward fluoride ion (Fâ) over other anions such as Clâ, Brâ, Iâ, CH3COOâ, H2PO4-, HSO4-, and OHâ. The ESIPT process of 1 is inhibited by the fluoride-induced H-bonding followed by deprotonation of NH of the 1-AAQ.
