  • Patent number: 9493656
    Abstract: Fluorescent phenyl xanthene dyes are described that comprise any fluorescein, rhodamine or rhodol comprising a particular C9 phenyl ring. One or both of the ortho groups on the lower C9 phenyl ring is ortho substituted with a group selected from alkyl, heteroalkyl, alkoxy, halo, haloalkyl, amino, mercapto, alkylthio, cyano, isocyano, cyanato, mercaptocyanato, nitroso, nitro, azido, sulfeno, sulfinyl, and sulfino. In one embodiment, halo and/or hydroxy groups are used. Optimal dyes contain a lower C9 phenyl ring in which both ortho groups are the same and the lower ring exhibits some form a symmetry relative to an imaginary axis running from the phenyl rings point of attachment to the remainder of the xanthene dye through a point para to the point of attachment. The phenyl xanthene dyes may be activated. Furthermore, the phenyl xanthene dyes may be conjugated to one or more substances including other dyes.
