Organic luminescent materials have been highlighted as an exciting research topic owing to their prominent potentials in light-emitting diodes, fluorescent sensors, optoelectronic devices, in vivo imaging, anti-counterfeiting, data storage, and information encryption. However, applications of tunable fluorescent materials in the solid states have been largely hampered because these luminescent systems generally require time-consuming organic synthesis procedures and suffer from reduced photoluminescence (PL) owing to the notorious aggregation caused quenching. Aggregation-induced emission (AIE) has proved a powerful antidote for the universal self-quenching problems in the field of organic luminescent materials. Inspired by the enhanced luminescence achieved by AIE, supramolecular approaches have been proposed and have facilitated the fabrication of a myriad number of smart luminescent materials.
