Dynamical studies of optically induced orientation processes in photochromic isomers: Experiment and theory
Photo-orientation by photoisomerization is quantified for individualizable photoisomers of diarylethene and spiropyran-type chromophores introduced into poly-methyl-methacrylate films. We have measured isomers optical transitions relative orientations, and photochemical quantum yields in these photo-anisotropic films.
