Light irradiation experiments on diarylethene, cis-1,2-dicyano-1,2-bis(2,4,5-trimethyl-3-thienyl)ethane (CMTE), under shear stress have been performed. From the results, it is apparent that the combination of shear stress and visible light of around 500 nm could induce the photoisomerization of CMTE to the closed-ring isomer. The present work shows that shear stress could adjust the wavelength of light for the photochromism from ultraviolet light region to visible light.
