Original Kurzfassung:
The invention relates to the release of singlet oygen by thermally activated decomposition of aromatic endoperoxide molecules in material systems [e.g. polymer (nano)particles or polymer films]. Due to the short lifespan and diffusion length of singlet oxygen, the technical problem is that the majorit of the decomposition may only take place if the singlet oxygen molecules can reach the target region. For example, either the penetration of the polymer particles into the cancer cells to be killed, or the settlement of bacteria on an implant coated with the polymer film, must be accomplished. It is necessary to allow adaptation of the time progression of the decomposition for the application. Tha adaptation is performed by chemically and/or physically modifying the functional structures present in the material system, each made of the molecule forming the endoperoxide and at least one adjacent molecule or the cage formed by all adjacent molcules. Potential applications are conceivable, as indicated, in pharmacy and medicine, as well as in production technology.
