True blue: Blue-emitting aluminum(III) quinolinolate complexes

The optical and electrochemical properties of blue-emitting heteroleptic aluminum(III) bis(2-methyl-8-quinolinolate)phenolate complexes are investigated. The results have suggested that the electronic effects that modulate the emissive properties in quinolinolate complexes are additive and the effects of individual substituents might be combined to obtain emitters of desired properties.
