  • Conjugated polycarbazole derivatives in Organic Light Emitting Diodes
    Patent number: 6630254
    Abstract: An Organic Light Emitting Diode (OLED) includes as active material a conjugated poly(N-alkyl-2,7-carbazole) derivative described by the formula: wherein n is an integer of about 3 to about 100, and R represents a substituant that is a linear or branched alkyl group containing 1 to 22 carbon atoms, or poly(ethyleneoxy), cyano, aryl, amide or benzoyl. Such OLEDs have improved light emitting properties, especially in the blue and red regions of the spectrum.
