Bridged Calix[4]
amnes can transport L.i + ion considerably and the selectivity for l.J* over Na Γ· is about 15 and 30, respectively, in the weak basic and neutral solution.

A novel fluorescent chemosensor 1 with two anthraceneisoxazolymethyl groups at the lower rim of calix[4]arene has been synthesized, which revealed a dual emission (monomer and excimer) when excited at 375 nm. This chemosensor displayed a selective fluorescence quenching only with Cu 2+ ion over all
