Abstract:
1. An organic light-emitting diode comprising an active layer of organic semiconductor material including at least partially triaryl-substituted Lewis acid units, which are polymerized or added as a polymer component to the organic semiconductor material to form a blend wherein: the Lewis acid units are borane units; and at least two of the three aryl substituents of the borane unit are part of a polymer main chain and not directly bonded to each other, wherein at least 50% of the recurring units of the organic semiconductor material are arylenevinylene units, paraphenylene derivative units or a combination thereof and between 1% and 50% of the recurring units are triaryl-substituted Lewis acid units; and wherein the paraphenylene derivative units are at least partially fluorene derivative units or polyspirofluorene.
