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.
三种不同颜色（绿黄色、橙色和红色）荧光和良好斯托克斯位移的苯并二吡咯（BODIPY）染料是从绿黄色 BODIPY 染料 PM546 开始合成的。染料的高斯托克斯位移是由于它们的激发态相对于高度扭曲的基态释放了空间应变。其中一种化合物可能是一种有用的水溶性荧光团，而另外两种则是很有前途的 H(+)传感器。
