Aggregation-induced emission

[1]

Aggregation-induced emission (AIE) is a phenomenon in which certain organic luminophores (fluorescent dyes) exhibit stronger emission of light in their aggregated or solid state compared to when they are in solution.[2][3][4] This counterintuitive behavior contrasts with most organic compounds, which typically show reduced photoemission in the solid state due to processes like aggregation-caused quenching. AIE is primarily attributed to restricted molecular motion in the aggregated state (decreased flexibility), which suppresses nonradiative energy dissipation and enhances fluorescence efficiency.[5] The increase of fluorescence emission intensity was also observed upon restriction of molecular motion due to host-guest interactions and viscosity increase,[6] which is not a common behavior of such host-guest complexes.[7]

Aggregation-induced emission enhancement

edit

The phenomenon in which organic luminophores show higher photoluminescence efficiency in the aggregated state than in solution is called aggregation-induced emission enhancement (AIEE). Some luminophores, e.g., diketopyrrolopyrrole-based and sulfonamide-based luminophores, only display enhanced emission upon entering the crystalline state. That is, these luminophores are said to exhibit crystallization-induced emission enhancement (CIEE).[8][9] Luminophores such as noble metallic nanoclusters show higher photoluminescence efficiency in the aggregated state than homogenous dispersion in solution. This phenomenon is known as Aggregation-Induced Emission (AIE).[10][11]

Aggregation-induced emission polymer

edit

Fluorescence-emission Polymer is a kind of polymer which can absorb light of certain frequency and then give out light.[12] These polymers can be applied in biomaterial area. Due to their high biocapacity and fluorescence, they can help researchers to find and mark the ___location of proteins. And polymers with property of aggregation-induced emission can also help to protect the healthy tissues from the harm of the medicines.[13]
