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 (F Γ ) over other anions such as Cl Γ ,
## Abstract An excitedβstate proton transfer (ESPT) process, induced by both intermolecular and intramolecular hydrogenβbonding interactions, is proposed to account for the fluorescence sensing mechanism of a fluoride chemosensor, phenylβ1__H__βanthra(1,2β__d__)imidazoleβ6,11βdione. The timeβdepend
