Two new fluorinated fluorescent dyes, 6,8-difluoro-7-hydroxy-4-methylcoumarin (Marina Blue) and 3-carboxy-6,8-difluoro-7-hydroxycoumarin (Pacific Blue), exhibit excellent photophysical properties among a series of novel fluorinated 7-hydroxycoumarins. Most of these fluorinated coumarins have quantum yields (0.63 to 0.89) equal to or higher than that
