Study of photo isomerization and photo induced anisotropy of a mesogenic azobenzen dye mixture in various solid and liquid matrices

摘要

We report the analyses of the photo induced anisotropy generated by a mesogenic azobenzene dye complex that is doped in isotropic and anisotropic matrices. By using time resolved polarized spectroscopy and photo induced dichroism studies, we show that this specific dye composition undergoes photo isomerization process, but has very limited angular mobility in all tested matrices.
