## Abstract Combinations of electron‐withdrawing and ‐donating substituents on the 8‐hydroxyquinoline ligand of the tris(8‐hydroxyquinoline)aluminum (Alq~3~) complexes allow for control of the HOMO and LUMO energies and the HOMO–LUMO gap responsible for emission from the complexes. Here, we present

Tris(8-hydroxyquinoline)aluminum (AlQ) powder has been characterized using photoluminescence and electron spin resonance (ESR). The broad asymmetric excitation band is centered at ∼425 nm, while the emission band centered at ∼505 nm is similar to those reported in films. A significant ESR signal wit
