'CH'/N substituted mer-Gaq3 and mer-Alq3 derivatives: An effective approach for the tuning of emitting color

Equilibrium geometry configuration of the 'CH'/N substituted Alq3 and Gaq3 derivatives are calculated by density functional theory. It is shown that the change of 'CH'/N substituted position on 8-hydroxyquinoline ligand is a powerful approach for the tuning of emitting color.
