Abstract
Inclusion complex of naphthalene with methyl-beta-cyclodextrin in water has been formed. The aqueous solutions of the various amounts of Co2+ve Mn2+salts have been added to naphthalene-methyl-beta-cyclodextrin (NAP-Me-β-CD) inclusion complexes. Fluorescence properties of the naphthalene (NAP) compound have been utilized to observe the changes in fluorescence intensities. Stern-Volmer quenching constants and fluorescence quantum yields have been calculated. Characterization of the resulting complex by FT-IR and 1H NMR technique has been determined. Fluorescence lifetime measurements have been made in the presence and absence of the quenching reagent and Gibbs free energy change has been calculated.
