摘要：

Fluorescence of tetraphenylporphyrin (TPP) doped in a polymer film is quenched by an electric field. Field-induced enhancement of the internal conversion from S-1 to the ground state is considered to be accelerated by a molecular association. Electroabsorption spectra and electrofluorescence spectra also show that change in molecular polarizability following excitation increases by a molecular association of TPP.
