Overview
DCJTB (4-(Dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran) is a high-efficiency red-emitting dopant widely used in OLED research, white and red electroluminescent devices, and organic photovoltaic interfaces. Structurally based on the dicyanomethylene-pyran (DCM) core, it offers strong photoluminescent response and effective suppression of concentration quenching.
The molecule features sterically hindered groups, including methyl-substituted julolidine and a tert-butyl moiety, which improve morphological stability and device performance by reducing non-radiative energy losses.
Typical Applications
- Red dopant in OLEDs (organic light-emitting diodes)
