A highly emissive 1,8-naphthalimide-based organic dye was synthesized. Interestingly, the luminogen exhibited obvious mechanofluorochromism behavior and good cell imaging performance. [Display omitted] •A new 1,8-naphthalimide-based organic luminescent molecule was synthesized.•The compound exhibited a bright solid-state luminescence.•The luminogen showed reversible mechanochromic luminescence phenomenon.•The luminogen displayed good performance for cell imaging. A 1,8-naphthalimide-based organic luminescent molecule has been designed and successfully synthesized via a Suzuki coupling reaction. The compound displayed a bright solid-state luminescence with the absolute fluorescence quantum yield up to 61.2%. Furthermore, the luminogen also exhibited reversible mechanofluorochromism behavior and good performance for cell imaging.
