Modern organic light emitting devices (OLEDs) present a new alternative to LCD screens and conventional lighting methods. In this field, devices using a multilayer setup show the highest efficiencies. This thesis covers synthesis and characterization of novel polymeric hole-transport materials based on triarylamines with backbone-linkage. After the film-preparation from solution, these polymers can be crosslinked by cationic polymerzation of oxetane moieties, which are located in the side-chains. The synthesis of the polytriarylamines was designed as a ‘molecular construction kit’ and allowes for an easy variation of the number of oxetane groups in the polymer and its electrochemical potential. After the crosslinking reaction was studied in details by means of UV-VIS and realtime-IR experiments, the optical and electronic properties of the polymers were investigated in hole-only devices and test-OLEDs and yielded good results.
