• Chromenoquinoline
• Near-infrared emitting
• Large Stokes shift
• LED
• Mitochondria imaging

In this work, we have designed and synthesized for the first time a series of red/near-infrared chromenoquinoline-based fluorescent dyes. These dyes show long wavelength emission (600-821 nm), large stokes shift and good photostability. It was shown that these newly developed dyes are capable of being used in LEDs, as well as in bioimaging of live cells and zebrafish. Importantly, the near-infrared chromenoquinoline dye can be used as targeting probe for mitochondria with good labeling properties.
