The concept of molecular machines, introduced by Feringa, Stoddard and Sauvage, has led to enormous public and
scientific interest about the mechanism of their action and possible tools for control. The existing single molecular
motors and switches are light/electricity fuelled and operate through elementary steps like bond isomerization or
bond formation/breakage. Tautomeric proton transfer, which leads to changes in the structure/properties of the organic
molecules under external stimuli, is another elementary process that is exploited for molecular devices design.
Currently applications like UV-protectors and functional chromic materials, useful action of some natural products
and drugs, etc., are based on proton transfer, as well as also undesired processes, such as the mutagenic mispairings
during DNA replication. The workshop gives an introduction to switching and device concepts, tautomerism and
proton transfer as possible realization, methods for investigation and basics of practical applications.
The format is a combination of lectures and journal club. The lecturers will first give an introduction to a specific topic,
then the students will read a key publication in which the presented concepts, processes, or methods are applied to
problems in chemistry, biology, or medicine. These applications are then discussed in a seminar.
