AIE fluorescent material

This exhibit introduces the unique characteristics and wide applications of aggregation induced luminescence (AE) materials to visitors through interactive models, physical samples, and multimedia displays. visitors can experience two types of luminescence mechanisms: the first set of models demonstrates the aggregation quenching (ACQ) effect, where a single molecule emits light but the luminescence weakens after aggregation; The second set of models presents the AE phenomenon of single molecule non luminescence and luminescence after aggregation. AIE material samples were also displayed on site, and their applications in biomedical, optoelectronic devices, and other fields were introduced through multimedia, highlighting their importance.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Aggregation induced emission (AIE) refers to the phenomenon where certain molecules exhibit low or no fluorescence when present in monomeric form, but their fluorescence performance is significantly enhanced when they aggregate to form aggregates. This phenomenon is opposite to that of traditional fluorescent molecules, which emit light in solution but undergo quenching in an aggregated state or at high concentrations, known as aggregation induced quenching (ACQ) phenomenon.
