Abstract

The synthesis and application of a series of crosslinkable bis(diphenylamine)-substituted mixed dihydroindeno[1,2-b]fluorenes as model systems for the fabrication of solution-processed, multilayer organic light-emitting diodes (OLEDs) is described. Introducing a novel functionalization approach by C(sp(3))-C(sp(2)) Suzuki-Miyaura reactions, the synthesis is based on a modular strategy, leading to eight nearly isoelectronic derivatives that allow for the observation of structure-property relationships in the context of crosslinkable hole-transport materials, e. g., for use in OLEDs. By systematically altering structural parameters, such as the number of crosslinkable oxetane moieties per molecule (2-6 moieties) and their position of attachment (geminal and/or lateral), process-relevant thermal properties such as thermal stability (T(d)95, 170-350 degrees C) and glass-transition temperature (15-100 degrees C) can be influenced and allow for the investigation of their impact on the crosslinking behavior and the resulting device performance.
