Abstract
A series of 4-substituted Alq3 derivatives have been synthesized. Photophysical properties of the complexes in solution have been studied in detail. The results show that Hammett Ïp constants of the substituents have a linear correlation with the emission maximum values of the aluminum complexes. Substitution at the 4-position improves the color purity of the emission and it has also a strong influence on the quantum yields. A new type of Alq3 derivative, tris-(4-hydroxypyridinoanthrene)aluminum, has a good quantum yield and high emission color purity.
