Abstract: The intensity of the fluorescent emission spectra of 2,7-dichlorofluorescein (510-640 nm) on excitation with 350 nm enhances on interaction with Cd2+ ions. Minor enhancement is observed with Na+ and Zn2+ ions, while no enhancement at all in fluorescence is observed with K+, Ca2+, Cu2+ and Ni2+. The enhancement in the fluorescence is explained on the basis of photoinduced electron transfer (PET) mechanism due to the binding of two Cd2+ ions to 2,7-dichlorofluorescein (log b = 3.80).
