报告简介

A scientific concept plays a critical role in the development of a new subject. Before the birth of Aggregation-induced emission (AIE), the concept of aggregation-caused quenching (ACQ) effect is considered as a general belief and a well-accepted concept for common organic luminophores. The ACQ concept has reformed peoples’ idea that the aggregation is harmful for solid-state light emission. Our group started from occasional interesting findings and has established the concept of AIE in 2001.[1-2] So far, the mechanism has evolved from restriction of intramolecular rotation to restriction of intramolecular motion and to recently the concept of through-space conjugation together with the through-bond conjugations, the emission types has ranged from solid-state fluorescence to room-temperature phosphorescence and further to aggregation-induced delayed fluorescence, the luminophores has changed from traditional luminophores to nonconventional luminogens. Diverse AIE luminogens with tunable color and high quantum yields have been explored, which finds diverse applications from optics and electronics to energy, environment and bioscience. Most importantly, the concept of AIE has gradually changed people’s thinking way about the aggregation of luminogen and put forth a revolution of luminogen research both conceptually and technically. In this talk, I will share with you our journey of AIE research, discusses our current understanding of the AIE mechanism, debates current challenges, and looks for the potential breakthroughs in this exciting research area.[3]
