Development of polymeric active layer for RGB light-emitting devices: a review

Due to the demand for materials that have promising properties for the electronic device market, the development of new conjugated polymers, where the π bond is responsible for the material's optoelectronic properties, has attracted the attention of the academic and industrial community owing to the easy processability, which can be performed from a polymeric solution, and to a great potential for the manufacture of devices such as cell phone screens, televisions, light-emitting diodes, and solid-state lighting (SSL). For SSL applications, usually, polymers capable of emitting red, green, and blue (RGB) light bands are used, which combined, generate white light. Thus, this review presents some of the most relevant works that aim at developing RGB devices that can be used for SSL applications.
