Abstract

We report on photoluminescence (PL) characteristics of dendrimers having (tris (8-hydroxy quinoline) aluminum) (Alq 3) as a core unit. Although Alq 3 derivatives are generally insoluble, the dendrimers were soluble in conventional organic solvents due to the presence of bulky dendron. We measured the transient PL and absolute PL efficiency of the dendrimers, dendron and AlClq 3 (core unit), and we clarified the location of π-conjugation, which is an origin of PL. The PL characteristics indicated that π-conjugation in the dendrimers is localized between a dendron and a quinoline ligand. Although the PL efficiencies are Φ PL = 20 - 40% in their solid films, the EL efficiencies are limited to Φ EL ∼ 10 -2%.
