Photon-mode modulation of fluorescence and electrical current with a photochromic conducting polymer

Fluorescence intensity and electrical conductivity of a photochromic conducting polymer based on photochromic diarylethene are modulated with the photochromic reactions induced by alternative irradiation with UV and visible light. Rectifying current-voltage characteristics of Al/polymer junction structure also shows marked change with the photochromic reaction of diarylethene units in polymer main chain.
