Quercetin, which is easily prepared from the flower buds of Sophora japonica, is found to exhibit aggregation‐induced emission (AIE) with excited‐state intramolecular proton transfer (ESIPT). In article number 1706196, Zhijun Chen, Shujun Li, Shouxin Liu, and co‐workers succeed in using the AIE fluorescence of quercetin with ESIPT for imaging the cytoplasm and for in vivo bioimaging. This is the first report of natural AIE luminogens.

光致发光：激发态分子内质子转移的新型槲皮素聚集诱导发射发光素（AIEgen）用于体内生物成像（Adv。Funct。Mater.11 / 2018）

槲皮素很容易从槐花的花蕾中制备，发现具有激发态分子内质子转移（ESIPT）的聚集诱导发射（AIE）。在1706196号文章中，陈志军，李树军，刘寿新及其同事成功地将槲皮素的AIE荧光与ESIPT结合使用，以对细胞质进行成像并进行体内生物成像。这是天然AIE发光剂的首次报道。
