Recent Progress in New AIE Structural Motifs

Aggregation-induced emission (AIE) is a fast-developing hot research area in recently years. AIE materials are fascinating because of their efficient aggregated state emission, strong photostability, structural and property diversity, etc. Besides the classical AIE luminogens such as tetraphenylethene and hexaphenylsilole, new AIE structural motifs have been updated rapidly. In this chapter, the development of AIE structural motifs in the past two years will be introduced with the emphasis on the structural design, the mechanistic understanding, and the luminescence behavior of new AIE systems.
