Defined halogen bond receptors for polymeric architectures: Adaption of behavior in solution as tool to create new functional materials
Polymer Materials
Final Report Abstract
Halogen bonds are a type of supramolecular bond formed between an anion and a polarized halogen atom. They are, therefore, related to hydrogen bonds. However, halogen bonds have hardly been applied so far and the project focused on the development of new halogen bond motifs. These were utilized to prepare new sensors for anions. For this purpose, the halogen bond motifs were bound to iridium complexes in order to be able to detect the anions via the emission of the complex. The concept was improved by optimizing the complex and using polymers. In addition, halogen bonds were incorporated into polymers by synthesizing functional monomers. These polymers showed switchable properties and were therefore able to heal mechanical damage. It was also possible to prepare polymers with shape-memory properties. Finally, these were also processed using 3D printing. The research results obtained pave the way for further investigations in the field of halogen bonds. The combination with polymers, in particular, promises new insights and potential fields of application, although questions about the molecular mechanism of the reversibility of the bond remain unanswered.
