| | 4-(DICYANOMETHYLENE)-2-METHYL-6-(4-DIMETHYLAMINOSTYRYL)-4H-PYRAN Usage And Synthesis |
| Description | DCM is a laser dye. | | Chemical Properties | red/brown crystals | | Uses | Laser dye. | | Uses | DCM can be used as a laser dye to enhance the emission of distributed feedback (DFB) device by Frster 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. | | 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. |
