Abstract

Picosecond laser spectroscopy was applied to the direct detection of photochromic reaction processes in a network polymer film prepared by oxidation polymerization of a diarylethene derivative. Both the coloration due to the cyclization and the decoloration via the cycloreversion took place in less than 30 ps. The time constants of both photochromic reactions were almost the same as those of diarylethene monomers obtained in the solutions, indicating that the oxidation polymer film system retains a similarly high response time as in the solution phase.
