Description

General description

Fluorescent dye

Application

DMQA may be used to explore the performance of indium tin oxide (ITO)/N,N′-bis-(1-naphthyl)-N,N′-diphenyl-1,1′-biphenyl-4,4′-diamine (NPB)/tris-(8-hydroxyquinolate)-aluminum (Alq3)/MgAg based organic light emitting diodes. When used as the emissive dopant in an Alq host layer, DMQA provides improved operational stability.

Green dopant for OLED applications.
