一般描述

4-（二氰甲烯基）-2-甲基-6-（4-二甲氨基苯乙烯基）- 4H -吡喃(DCM)是一种红色激光染料，以二氰甲烯基为电子受体，二甲基苯胺为电子供体。它有一个π-共轭4H -吡喃-4- ylidiene，用于连接受体和供体基团。它可以用作掺杂剂，也可以用于有机固态激光器。

应用

DCM可作为一种激光染料，通过FÖrster共振能量转移(FRET)来增强分布式反馈(DFB)器件的发射。它可被用作覆盖层，允许在有机发光二极管(OLED)中将蓝色发射转换为红色发射。DCM还可能应用在在增强金属有机框架(MOF)、染料敏化太阳能电池(DSSC)和极性传感器等不同器件的能量转移方面。

特点和优势

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。
