4-(Dicyanomethylene)-2-tert-butyl-6-(1,1,7,7-tetramethyljulolidin-4-yl-vinyl)-4H-pyran Usage And Synthesis
DescriptionDCJTB, a dicyanomethylene-4H-pyran (DCM) derivative, is one of the most promising dopant materials. It has been widely used in red and white OLEDs.
UsesRed dopant for white organic light emitting diodes (OLEDs). 1 DCJTB may be used as an emitting layer to enhance the performance of OLEDs.
General DescriptionDCJTB 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.
