Displacement of the loosely encapsulated fluorescent indicator coumarine 343 (F) from a dicopper( II ) cryptate enables the selective fluorimetric detection of the HCO 3 − ion (A) in water (see scheme, •○=Cu 2+ ). The fluorophore is quenched when encapsulated, but displays its full emission when released to the solution.
