Sources/Uses

Used in organic light-emitting devices (OLED) as an electron transport and/or light emitting layer; [ChemIDplus] "Tris(8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al(C9H6NO)3. Widely abbreviated Alq3, it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands. . . . Alq3 is a common component of organic light-emitting diodes (OLED's). Variations in the substituents on the quinoline rings affect its luminescence properties. [Wikipedia]
