Abstract

Investigations into the lithium fluoride and cesium fluoride/tris(quinolin-8-olato) aluminum (LiF-Alq₃ or CsF-Alq₃) Lewis acid-Lewis base pairs have been undertaken using hybrid density functional calculations. The results of the calculations clearly show that there is a strong interaction that occurs between the metal fluoride and both the facial and the meridional isomers of Alq₃. This strong interaction has the effect of modifying the electronic structure of Alq₃ and can be thought of as the first step in the formation of the highly effective Alq₃/Metal Halide/Al electron injection contact.
