A simple, direct route to purify, as-deposited, materials for the fabrication of organic light emitting devices (OLEDs) is reported. In situ purification of 8-tris-hydroxyquinoline aluminum (Alq(3)) can lead to devices with electroluminescence characteristics comparable to those of device., made with materials pre-purified via traditional separation processes such as recrystallization or vacuum sublimation.
