Organic Materials Chemistry - Service and Equipment

We are able to perform custom synthesis and we are prepared to solve even demanding analytical tasks. Table 1 summarizes the experimental techniques available in the department.

Please do not hesitate to contact Prof. Dr. Uwe Beginn or Dr. Tristan Wegner and challenge us with your task.
