Abstract

Bilayer organic light emitting diodes (OLED), based upon vacuum deposited molecules, or single layer OLEDs, based upon spin-cast polymeric materials, doped with these same molecules, produce light from emissive states of the lumophores which are created through annihilation reactions of radical species, which can be modeled through solution electrochemistry. Differences seen in solution reduction and oxidation potentials of molecular components of OLEDs are a lower limit estimate to the differences in energy of these same radical species in the condensed phase environment. The light emitted from an aluminum quinolate (Alq₃)/triarylamine (TPD)-based OLED, or an Alq₃/PVK single layer OLED, can be reproduced from solution cross reactions of Alq₃/TPD.
