  • Patent number: 5514710
    Abstract: The invention describes the synthesis and use of photoactivated (or caged) fluorescent dyes. Upon illumination at less than about 400 nm the caged dyes release highly fluorescent, water soluble hydroxypyrenesulfonic acid dyes according to the following equation: ##STR1## X, Y, and Z are independently sulfonic acid, a sulfonic acid salt, a hydroxyl group, or hydrogen, with at least one of X, Y, and Z being a sulfonic acid or sulfonic acid salt. LINK is either an ether linkage or a carbonate linkage. BLOCK is a caging group whose photolysis results in liberation of a free hydroxypyrenesulfonic acid dye.The caged fluorescent dyes are useful for application in aqueous solutions, including fluids of biological origin. The caged dyes of the present invention are especially useful for flow tagging velocimetry.
