双氰亚甲基- 4h -吡喃（DCM）发色团是典型的供体-pi-受体（D-pi-A）型发色团，具有超快速内部电荷转移（ICT）过程产生的宽吸收带。1989年，Tang等人首次在有机电致发光二极管（oled）中引入DCM衍生物作为高荧光掺杂剂。基于离子诱导吸收或发射位移的DCM发色团集成ICT发色团-受体系统是实现分子逻辑门逻辑表达的一种便捷方法。近年来，各种dcm型衍生物因其优异的光电性能和多样的结构修饰而被探索。这篇专题文章深入探讨了DCM发色团的结构修饰如何用于OLED发射器、逻辑门和光学化学传感器。此外，还介绍了DCM衍生物的聚集诱导发射（AIE）技术在光学领域的进一步应用。
Dicyanomethylene-4H-pyran (DCM) chromophores are typical donor-pi-acceptor (D-pi-A) type chromophores with a broad absorption band resulting from an ultra-fast internal charge-transfer (ICT) process. In 1989, Tang et al. firstly introduced a DCM derivative as a highly fluorescent dopant in organic electroluminescent diodes (OLEDs). Integration of ICT chromophore-receptor systems based on DCM chromophores with ion-induced shifts in absorption or emission is a convenient method to perform the logic expression for molecular logic gates. In recent years, various DCM-type derivatives have been explored due to their excellent optical-electronic properties and diverse structural modification. This feature article provides an insight into how the structural modification of DCM chromophores can be utilized for OLED emitters, logic gates and optical chemosensors. In addition, the aggregation-induced-emission (AIE) of DCM derivatives for further optical applications was also introduced.
