A four-state fluorescent switch is realized in a single supramolecular construct via tuning the emission of two types of fluorophores.
An AIE fluorescent switch exhibited multi-parameter detection properties for pH, sulfite anion and pressure with good linear relationships.
An organic single-molecule RGB luminescence material with a high quantum yield was realized by introducing the ESIPT and TBET mechanisms and combining an AIEE luminophore with a fluorescent switch.
