In the year of 1952 Fischer and Hirshberg discovered the photochromic reaction of spiropyrans. Since then a broad application range for spiropyran compounds has been developed. The scope of application embraces the field of molecular “switches” as well as photosensitive polymers containing spiropyrane units. These applications are not only based on the change of colours induced by the conversion of the closed spiropyrane to the open merocyanine-form, but also on the change of the chemical and physical properties.

In our group the conversion of spiropyrane units in copolymers is studied qualitatively and quantitatively using NMR spectroscopy. Our cooperation partner on this LOEWE research topic “Soft Control” is the group of Professor Biesalski.
