Denatured tris(quinolin-8-olato)aluminium: a new material for organic electroluminescent cells

Abstract

Tris(quinolin-8-olato)aluminium (Alq₃) was denatured by a heating process. The denaturation was followed with infrared spectroscopy, differential thermal analysis and elemental analysis. The denatured Alq₃ showed electroluminescent (EL) characteristics no weaker than normal Alq₃.
