Description

Description générale

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.[1][2]

Application

DCM can be used as a laser dye to enhance the emission of distributed feedback (DFB) device by FÖrster resonance energy transfer (FRET).[3] It may be used as a capping layer that allows the conversion of blue to red colored emission in organic light emitting diodes (OLED).[4] DCM may also find potential applications in the enhancement of energy transfer of different devices like metal organic frameworks (MOFs),[5] dye sensitized solar cells (DSSCs)[6] and polarity sensors.[7]

Caractéristiques et avantages

Voltage-tunable multicolor emission with enhanced luminance (~1000 cd/m²) was observed using varying amounts of DCM dye in a polymer light-emitting diode (PLED).[8]
