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.

Application

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