Femtosecond dynamics of the photochromic reaction of a thiophene oligomer with a diarylethene structure in solution was analyzed by transient absorption spectroscopy. It was found that the intermediate species with an absorption maximum at ∼515 nm was formed within 100 fs and that the closed-ring form of the thiophene oligomer was formed mainly from the intermediate with a time constant of ∼1.1 ps.
