Abstract

We have prepared a simple star-shaped oligo(aniline), TDPB, and characterised it in detail by MALDI-TOF MS, UV-vis-NIR, TD-DFT, CV and EPR. TDPB is part of an underdeveloped class of π-conjugated molecules with great potential for organic electronics, display and sensor applications. It is redox active and reacts with acids to form radical cations. Acid-doped TDPB shows behaviour similar to discotic liquid crystals, with X-ray scattering investigations revealing columnar self-assembled arrays. The combination of unpaired electrons and supramolecular stacking suggests star-shaped oligo(aniline)s like TDPB have the potential to form conducting nanowires and organic magnetic materials.
