The Cover Feature shows the fluorescent “turn‐off” and “turn‐on” states of 1,8‐naphthalimide fluorogenic click probes though the hand‐drawn cartoon of lotus (credit: Xiang Li, one of the authors). The “In bud” state of the lotus represents the 4‐hydrazone‐1,8‐naphthalimides, which is in “turn‐off” state, while the “blooming” state of the lotus represents the “turn‐on” state of 1,8‐naphthalimide cycloadducts after click reaction. The “open” and “close” of lotus petals reflect well the “fluorescent” and “nonfluorescent” properties of these probes. More information can be found in the Communication by Y. Tian et al.
