Organic fluorophores with dual‐emission and large Stokes shifts are attracting great attention due to their importance in fundamental research and technique applications. This Progress Report gives an account on how a novel luminescence mechanism termed vibration‐induced emission (VIE) is established. The VIE mechanism is coined for the rationalization of an alterable dual emission of V‐shaped N,N′‐disubstituded‐dihydribenzo[a,c]phenazines (DHPs), which are originated from a bent‐to‐planar vibration and the reverse in the excited state. The validation of the VIE mechanism is highlighted, such as the work reporting the utilization of chemically‐locked strategy to snapshot the excited‐state planarization of DHPs, and the application of the approach of steric hindrance‐induced planarization to tune the ground‐state geometry of DHPs. Moreover, the emerging applications of this VIE concept in photoelectric and biomedical disciplines are summarized. Additionally, further development of the VIE systems as well as the remaining challenges are prospected. This report could arouse wide interest from various fields to the specific area of VIE, which would not only broaden the VIE territory but also enlarge the scope of advanced functional materials.

N，N'-二取代-二氢苯并[a，c]吩嗪的振动诱导排放（VIE）：基本理解和新兴应用

具有双发射和大斯托克斯频移的有机荧光团由于其在基础研究和技术应用中的重要性而备受关注。该进展报告说明了如何建立一种称为振动感应发射（VIE）的新型发光机制。VIE机制的产生是为了合理化V形N，N'-二取代-二氢苯并[ a，c] phenazines（DHPs）源自弯曲到平面的振动，而在激发态时则相反。重点介绍了VIE机制的验证，例如报告了化学锁定策略的应用以描述DHP激发态平面化的快照，以及空间位阻诱导平面化方法在调整基态几何中的应用的DHP。此外，总结了这种VIE概念在光电和生物医学领域的新兴应用。此外，还有望进一步开发VIE系统以及其他挑战。该报告可能引起各个领域对VIE特定领域的广泛兴趣，这不仅会拓宽VIE的领域，而且会扩大高级功能材料的范围。
