DCJTB, DCM derivate

DCJTB, one of the most promising dopant materials

Widely used in red and white OLEDs

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.

With four methyl bulky substituents on the julolidine moiety, and tert-butyl group on the pyran moiety of DCM backbone stucture, DCJTB can efficiently prevent concentration quenching between the emitting materials, which leads to improved device electroluminescence efficiencies.

DCJTB has also been used as an interface material between the dye and acceptor in small molecule organic heterojunction solar cells, retarding the charge recombinations between the donor and the acceptor.
