| Outline of Final Research Achievements |
The light irradiation experiments on photochromic molecules have been performed in the solid state under shear stress. The purpose is the development of the tuning method for the light wavelength inducing photochormism using the external stress. As the results, we have found the visible light-induced photochromism in the three diarylethenes CMTE, PFCP, BFCP under shear stress. This phenomenon was related to a redshift of the absorption band spanning from UV region caused by shear stress. Spiropyran and azobenzene derivatives in polymers, multilayer thin films or clay intercalation compounds have different molecular alignments from those in crystal. Therefore, photochromic molecules in these substances are compressed by the moderated or enhanced external stress. These substances are expected to be useful tools for the adjustment of external stress.
