In the course of our program of developing integrated (intrinsic)
fluoroionophores we demonstrated that photoinduced intramolecular
charge transfer from the ionophore to the ð-conjugated system led
to release of the cation during the excited-state lifetime of the
probe,2 but the mean diffusion length of the cation is only 10 Å
for 1 ns,3 and the switching action is quickly reversed as the system
loses its excitation energy and returns to the original ground state
