4-(DICYANOMETHYLENE)-2-METHYL-6-(4-DIMETHYLAMINOSTYRYL)-4H-PYRAN Usage And Synthesis

Chemical Properties

red/brown crystals

Uses

DCM can be used as a laser dye to enhance the emission of distributed feedback (DFB) device by F?rster resonance energy transfer (FRET). It may be used as a capping layer that allows the conversion of blue to red colored emission in organic light emitting diodes (OLED). DCM may also find potential applications in the enhancement of energy transfer of different devices like metal organic frameworks (MOFs), dye sensitized solar cells (DSSCs) and polarity sensors.

Uses

Laser dye.

Definition

ChEBI: 4-(dicyanomethylene)-2-methyl-6-(4-(dimethylamino)styryl)-4H-pyran is a dinitrile. It has a role as a fluorochrome.

General Description

4-(Dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) is a red laser dye that consists of dicyanomethylene as an electron acceptor and dimethylaniline group as an electron donor. It has a π-conjugated 4H-pyran-4-ylidiene which bridges both the acceptor/donor groups. It can be used as a dopant and also in organic solid state lasers.
