Aggregation‐induced emission luminogens (AIEgens) that undergo excited‐state intramolecular proton transfer (ESIPT) have many applications in bioimaging since they have high quantum efficiency in the aggregated state and a low background signal in aqueous solutions because of their large Stokes shift. One disadvantage of many of the AIEgens with ESIPT that has been described so far is that they require time‐consuming synthesis and the use of toxic reagents. Another disadvantage with most of these materials is that they are only used for bioimaging in cells and are unsuitable for in vivo bioimaging. Herein, a new AIEgen with ESIPT, quercetin (QC) is described, which is easily prepared from Sophora japonica. AIE is attributed to crystallization‐promoted keto emission. The fluorescence is temperature dependent and shows strong resistance to photobleaching. QC AIEgen with ESIPT is shown to have excellent biocompatibility and is successfully used for bioimaging both in cellular cytoplasm and in vivo.
