产品介绍 4-（二氰基亚甲基）-2-甲基-6-（4-二甲基氨基苯乙烯基）-4H-吡喃（DCM）是一种红色激光染料，由作为电子受体的二氰基亚甲基和作为电子供体的二甲基苯胺基组成。 它具有一个π-共轭的4H-吡喃-4-亚基烯，它桥接两个受体/供体基团。 它可用作掺杂剂，也可用于有机固态激光器。 在聚合物发光二极管 (PLED) 中使用不同量的 DCM 染料，可观察到具有增强亮度（约 1000cd/m2）的电压可调式多色发光。 用途 DCM可以用作激光染料，通过FÖrster共振能量转移（FRET）来增强分布式反馈（DFB）器件的发射。它可以用作覆盖层，允许在有机发光中将蓝色发射转换为红色发射 DCM还可能在增强诸如金属有机框架（MOF），染料敏化太阳能电池（DSSC）[7]和极性传感器之类的不同设备的能量传递中找到潜在的应用。 Product Introduction 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. 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). Application DCM can be used as a laser dye to enhance the emission of distributed feedback (DFB) device by FÖrster 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)[7] and polarity sensors.
