摘要

Organic light-emitting diodes (OLEDs; have been successfully commercialized in the mobile phone market, and considerable effort is currently being devoted to applying OLEDs in other commercial applications such as televisions (TVs) and lighting. OLED displays are becoming the mainstream of next-generation displays to replace the liquid crystal display (LCD). Many technological advances are needed to apply OLEDs in TVs and lighting, but the development of fluorescent materials that emit short-wavelength blue light is especially essential for the future use of OLED displays. Usable fluorescent blue light-emitting materials must not only emit a deep blue light but also be thermally stable, highly efficient and have a long lifetime. There has been recent progress in research on blue fluorescent materials, and a resulting plethora of information. These results require a systematic organization to decipher the relationships between chemical structure and OLED device performance. We aim to address this need in the current review by systematically classifying blue fluorescent materials from a conceptually new "core-side" perspective, summarizing features that increase efficiency to improve OLED device performance, and providing a practical guideline for studying new blue fluorescent materials. This article summarizes the chemical structures and efficiency characteristics of selected 126 blue fluorescent materials. Systematic studies based on chemical structure and increased efficiency effects are necessary to develop highly efficient deep-blue fluorescent materials, and such studies on blue fluorescent materials are expected to become more prevalent in the fields of TV and lighting, as well as future flexible displays. Also, a systematic classification and understanding of the materials that have already been reported will aid the development and study of new light-emitting materials through quantitative and qualitative approaches.
