  • Fluorogenic compounds converted to fluorophores by photochemical or chemical means and their use in biological systems
    Publication number: 20100029952
    Abstract: Fluorophores derived from photoactivatable azide-pi-acceptor fluorogens or from a thermal reaction of an azide-pi-acceptor fluorogen with an alkene or alkyne are disclosed. Fluorophores derived from a thermal reaction of an alkyne-pi-acceptor fluorogen with an azide are also disclosed. The fluorophores can readily be activated by light and can be used to label a biomolecule and imaged on a single-molecule level in living cells.
