Three boradiazaindacene (BODIPY) dyes with different‐coloured (greenish‐yellow, orange and red) fluorescence and good Stokes shifts were synthesised starting from the greenish‐yellow BODIPY dye PM546. The high Stokes shifts of the dyes are due to the release of the steric strain in their excited states relative to that in the highly twisted ground states. One of these compounds might be a useful water‐soluble fluorophore, whereas the other two are promising H + sensors.
