New polycyclic aromatic hydrocarbon dopants for red organic electroluminescent devices

Two new anthracene derivatives with red emission have been synthesized. The materials were characterized with photoluminescence spectroscopy, and showed emission peaking at over 600 nm. Organic light-emitting devices were fabricated by using these derivatives as dopants. The devices have a maximum efficiency of 0.6 cd A(-1) and an emission peak at 617 nm. The results of color tuning and fluorescent yield enhancement for anthracene derivatives are presented.
