A reversible chemical reaction of the photochromic system, driven by light and producing highly polar metastable species, manifests itself in a reversible modification of dark currents and photocurrents. The behaviour of the samples is explained assuming a reversible production and annihilation of dipolar traps associated with the polar molecules produced in the photochromic process. Use of similar materials as elements of molecular electroactive systems is postulated.
