Wöhrle, DieterLapok, LukaszLukaszLapok2020-03-092020-03-092006-09-16https://media.suub.uni-bremen.de/handle/elib/2293The main focus of this work was the synthesis of differently charged (negatively, positively and zwitterions) compounds, potentially applicable as photocatalysts. In order to induce water solubility, different functional groups have been added to the macrocycle framework, i.e. salts of sulfonic groups and quaternary aromatic amines. The following macrocycles were investigated: a) metal-free, silicon and germanium phthalocyanines, b) oxophosphorus(V) and hydroxysilicon(IV) triazatetrabenzcorroles, c) subphthalocyanines, d) metal-free and zinc porphyrins. Synthesis of these compounds was undertaken purposely, i.e. to find possibly stable and efficient photosensitizers in the photocatalytic photo-oxidation reactions.eninfo:eu-repo/semantics/openAccessphotocatalystphthalocyaninetriazatetrabenzcorrolesubphthalocyanineporphyrinphoto-oxidation540Dissertationurn:nbn:de:gbv:46-diss000104998
