Polymer chemistry: As the challenges continually change, an intensive research in synthetic polymeric materials is essential. Therefore, Ritter group's work is focussed on microwave assisted polymer synthesis, cyclodextrins in polymer synthesis, enzymes for polymer synthesis, materials for dental technology and photosensitive materials.
Prof. Ritter edited the thematic issues in the Beilstein Journal of Organic Chemistry:
