Aggregation‐induced emission (AIE) refers to a photophysical effect that the luminescence of aggregates is stronger than that of the dispersed state. Since the concept of AIE was coined by Professor Ben Zhong Tang and co‐workers in 2001, AIE has evolved from a simple luminescent phenomenon to a multidisciplinary research field with a widespread influence. It has changed people's way of thinking about chromophore aggregation and greatly promoted the development of advanced luminescent materials. During the 20‐year development, diverse AIE luminogens (AIEgens) with attractive functionalities have been developed and remarkable achievements have been made in the mechanistic study and high‐tech applications of AIEgens. In this review, we provide an overview of the historical development and representative achievements of AIE research. Perspectives on the application of AIE in aggregate science are also briefly discussed to guide the future development in this field.

聚集引起的排放：化学和材料科学领域的后起之秀

聚集诱导发射（AIE）是指一种光物理效应，即聚集体的发光比分散态的发光更强。自从2001年Ben Zhong Tang教授和他的同事提出了AIE的概念以来，AIE已经从简单的发光现象发展成为具有广泛影响力的多学科研究领域。它改变了人们对发色团聚集的思考方式，极大地促进了高级发光材料的发展。在20年的发展过程中，开发了具有有吸引力功能的多种AIEgens（AIEgens），并在AIEgens的机理研究和高科技应用中取得了显著成就。在本文中，我们概述了AIE研究的历史发展和代表性成就。
