We prepared light emitting diodes with a discotic main chain polymer doped with a tristilbene amine derivative. X‐ray investigations showed the formation of a hexagonal columnar structure in the annealed devices. This increased order leads to a significant reduction of the onset voltage for light emission down to 4 · 10 5 V/cm.
