4-(Dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran Usage And Synthesis

Description

DCJTB, a dicyanomethylene-4H-pyran (DCM) derivative, is one of the most promising dopant materials. It has been widely used in red and white OLEDs.

Uses

Red dopant for white organic light emitting diodes (OLEDs). 1 DCJTB may be used as an emitting layer to enhance the performance of OLEDs.

General Description

DCJTB belongs to a class of laser dyes useful for solar-concentrator applications. Pure DCJTB can be prepared from unsymmetrical 4-(dicyanomethylene)-2-(t-butyl)-6-methyl-4H-pyran directly. These red dopants have high photoluminescent (PL) quantum yields. Its photoluminescent properties have been reported in a study.
