Aggregation-induced Emission: A Curious Case of Molecular Luminescence

Aggregation-induced emission (AIE) is an interesting luminescence phenomenon. This process describes how unity in the molecular world can produce bright emissions (luminescence). Chemists have adopted this technique to design various luminescent materials to develop efficient diagnostics and therapeutics. In this article, a concise description of AIE and its development is documented. The application of AIE is significant in the field of materials and biology. In the last part of the article, a brief description of various uses is presented.
