targeting and specific suborganellular localization combined with an efficient pathology associated enzymatic activation of drugs in drugdelivery systems may exhibit a clear advantage over conventional cancer treatment. Here, a mitochondria targeted aggregationinducedemission (AIE) fluorophore further conjugated with an NAD(P)H:quinone oxidoreductase-1 (NQO1) cleavable masking unit showed preferential

specifically, the solid-state fluorescence of D-π-Atype compounds 1, 3, 4, and 6 can be reversibly switched by successive mechanical grinding and solvent fuming, while D-π-Atype compounds 2 and 8 display irreversible mechanofluorochromism behaviors. Remarkably, when the pristine powders of these mechanical force-responsive fluorophores are ground, 1 and 2 exhibit an obvious blue-shift, while 3, 4, 6, and

the design and synthesis of a series of tetraphenylethylene (TPE) derivatives based on TPE-A or A-π-TPE-π-A molecular structure featuring various electron-acceptor (A) groups. The photophysical properties of the new LDS compounds were systematically studied in 1,4-dioxane solution and film (Zeonex) by UV–visible absorption and fluorescence spectroscopy, and electrochemical properties studied by cyclic
