✦ Synopsis

Displacement of the loosely encapsulated fluorescent indicator coumarine 343 (F) from a dicopper(II) cryptate enables the selective fluorimetric detection of the HCO3 (-) ion (A) in water (see scheme, •○=Cu(2+) ). The fluorophore is quenched when encapsulated, but displays its full emission when released to the solution.
