Ultrafast excited states dynamics of two orthogonal molecular photoswitches — •Tanja Schmitt¹, Li-Yun Hsu², Eva Blasco², and Petra Tegeder¹ — ¹Physical Chemistry, Ruprecht-Karls-Universität Heidelberg — ²Organic Chemistry, Ruprecht-Karls-Universität Heidelberg

Molecular photoswitches are widely used in physics, chemistry, biology and material sciences. The use of multiple photoswitches at one time opens diverse opportunities for further improved and more complicated systems. This requires orthogonal addressability of the photoswitches and ideally reversible processes. Herein, we report a mixture of two reversible and orthogonal photoswitches which could potentially be used in four-dimensional printing. We report the first study of their ultrafast excited state dynamics when they are addressed orthogonally as well as simultaneously to gain insight in their interaction. In addition, the environmental influence of the excited state dynamics of the orthogonal photoswitches is examined using different solvents as well as films.
