BODIPY-derivative

BODIPY is a boron difluoride group BF2 joined to a dipyrromethene group C9H7N2. BODIPY and many of its derivatives have received attention recently for being fluorescent dyes with unique properties. They strongly absorb UV-radiation and re-emit it in very narrow frequency spreads, with high quantum yields, mostly at wavelengths below 600 nm. They are relatively insensitive to the polarity and pH of their environment and are reasonably stable to physiological conditions. Small modifications to their structures enable tuning of their fluorescence characteristics
