Implication
Review demonstrates aggregation-induced emission driven by restricted intramolecular rotation in novel luminogens, highlighting wide utility across bioimaging, chemical sensing, and optoelectronics.
Key Points
- To elucidate the operational mechanism behind aggregation-induced emission and develop high-efficiency luminescent materials for biological, sensory, and optoelectronic applications.
- Synthesized diverse fluorescent and phosphorescent luminogen systems engineered to span the visible spectral region.
- Investigated the photophysical mechanism governing luminescence switching upon molecular aggregation.
- Tested luminogen performance across platforms including chemical sensors, biomolecular probes, immunoassay markers, and organic light-emitting diodes.
- Identified restriction of intramolecular rotation during aggregation as the primary mechanism preventing non-radiative energy dissipation and activating bright emission.
- Achieved luminescence quantum yields reaching up to unity across the complete visible spectrum.
- Successfully deployed luminogens as versatile sensors for ions, explosives, and biopolymers, as well as active layers in light-emitting diodes.
