Aggregation-Induced Emission: New Vistas at the Aggregate Level.

Area of Science:

• Photophysical phenomena
• Materials science
• Supramolecular chemistry

Background:

• Aggregation-induced emission (AIE) is a phenomenon where molecular aggregates emit stronger light than individual molecules.
• AIE research has significantly advanced material development, mechanistic understanding, and high-tech applications over the past two decades.
• Molecular aggregates exhibit unique properties and functions not present in isolated molecular species.

Purpose of the Study:

• To review recent advancements in aggregation-induced emission (AIE) and related fields.
• To focus on novel material properties arising from molecular aggregates at the supramolecular level.
• To inspire further research into molecular ensembles for material and biological science progress.

Main Methods:

• Literature review of AIE research.
• Analysis of material properties beyond the molecular level.
• Exploration of AIE in material and biological contexts.

Main Results:
