remarkably enhanced aggregation-inducedemission (AIE) activity than the parent. Although both the parent and the derivatives have the characteristic of an excited state intramolecular proton transfer (ESIPT), the AIE mechanism of 2 and 3 is totally different from that of 1. The considerably stronger emission of 3 than that of 2 should be attributed to the unique crystallization-inducedemission enhancement
