Abstract
A technology that shows great promise for application in novel flat panel displays is based on electroluminescence (EL) of organic light-emitting devices (OLEDs). Aluminum tris(8-hydroxy quinoline) (Alq3)-type materials are very important as emitter materials in OLEDs. Systematic experimental and theoretical studies of these materials are crucial in order to elucidate the relationship between structure and function of EL materials and ultimately optimize device performance. It has been demonstrated both theoretically and experimentally that the photoluminescence (PL) emission energies of Alq 3 can be tuned by adding substituents to the quinolate ligand. The electronic and structural changes associated with such substitutions can dramatically affect the resulting PL and EL efficiencies. The first systematic study of the PL and EL properties of a series of methyl-substituted quinolate tris-chelates of aluminum, gallium, and indium is reported. Detailed description of synthetic routes, characterization results, photophysical data, device data, and x-ray absorption data are presented. The effect of methyl and metal ion substitution on EL is discussed with respect to changes in required parameters.
