Abstract

(Chemical Equation Presented) Calixarene-based fluorescent chemosensor 1 with two fluorogenic pyrene units conjugated to amide groups as guest recognition sites is synthesized. Complexation of F^- by 1 causes a red shift of its absorption band to 400 nm (Δλ = 54 nm) and a blue shift of the excimer emission to 470 nm (Δλ = 12 nm) together with enhanced fluorescence intensity. The blue-shifted excimer emission is attributed to a pyrene dimer formed in the ground state, a so-called static excimer.
