일반 설명

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.

애플리케이션

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) and polarity sensors.

특징 및 장점

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).

Fluorescence Quenching Microscopy: Imaging Two-Dimensional Materials

Developed in the last several years, fluorescence quenching microscopy (FQM) has enabled rapid, inexpensive, and high-fidelity visualization of two-dimensional (2D) materials such as graphene-based sheets and MoS2.

Graphene in Biotechnology

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.
