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. Both the meriodonal and facial isomers are known as well as several polymorphs (different crystalline forms).[1] The compound is prepared by the reaction of 8-hydroxyquinoline with aluminium(III) sources[2]
- Al3+ + C9H6NOH → Al(C9H6NO)3 + 3 H+
Alq3 is a common component of organic light-emitting diodes (OLED's). Variations in the substituents on the quinoline rings affect its luminescence properties.[3]
