Aggregation-enhanced excimer emission (AEEE) based on pyrenylchalcone and 2-to-4 molecular decoder by biothiols and polyanions in aqueous media

- A novel aggregation-enhanced excimer emission fluorophore (pyrenylchalcone).
- A turn-on water-soluble probe (orange) for polyanions.
- Better than the “blue-to-green” change of other pyrene probes.
- A turn-on water-soluble probe (blue) for biothiols.
- Environmentally-friendly 2-to-4 molecular decoder (visible to naked eyes).
