  abstract  = {The aim of this work was the selective functionalisation of tribenzotriquinacene (TBTQ) in order to extend the aromatic system and tune the electronic properties. The synthesised molecules could be starting materials for a model system of a defective graphene fragment. The "triple cyclisation pathway" by Hopf et al. was adapted and fluorinated tribenzotriquinacenes were synthesised for the first time. Phenanthrene groups were also introduced in other model systems and the crystal structures of phenanthrene functionalised TBTQs were compared with the parent molecules. In addition, the arrangement of TBTQ and centro methyl functionalised TBTQ was investigated on a Ag(111) surface for the first time using scanning transmission microscopy (STM). Different arrangements were observed, depending on the coverage of the surface. The insights gained about the interaction between TBTQs as well as their synthesis provide a foundation for further work and potential applications as components in organic electronic devices.},
