Abstract

Fluorescence of (-)-bis(1,2;4,5-di-O-isopropylidene-β-D-fructopyranyl) 1,4-naphthalenedicarboxylate (NDC) co-doped with 1,1-diphenylpropene (DPP) in a PMMA polymer film is quenched by an external electric field, which however enhances the fluorescence from an exciplex formed between DPP and NDC. This contrasting fluorescence behavior is attributable to the enhanced efficiency of exciplex formation. The magnitudes of the difference in dipole moment and molecular polarizability between the ground state and the excited state of NDC or DPP have been also determined from the Stark shift of the absorption and emission spectra.
