Original Abstract
Kinetics of photochromic reaction of spiropyrane dissolved in a poly(phenylenevinylene) derivative MEH-PPV was studied by optical and impedance spectroscopy. Spiropyrane forms metastable, highly polar merocyanine under illumination with light of an appropriate wavelength. Due to charge dipole interactions, charge carrier traps are formed and affect electrical properties of the polymer matrix, namely capacitance and photoconductivity.
