Abstract
The intensity of the fluorescent emission spectra of 2,7-dichlorofluorescein (510-640 nm) on excitation with 350 nm enhances on interaction with Cd 2+ ions. Minor enhancement is observed with Na + and Zn 2+ ions, while no enhancement at all in fluorescence is observed with K + , Ca 2+ , Cu 2+ and Ni 2+ . The enhancement in the fluorescence is explained on the basis of photoinduced electron transfer (PET) mechanism due to the binding of two Cd 2+ ions to 2,7-dichlorofluorescein (log β = 3.80).
