The ethenyl-substituted dyes generally have the structure: wherein at least one of the fluorophore substituents R1-R7, is an ethenyl group of the formula -CXm=CYm-Zm, where m is any combination of locations 1, 2, 3, 4, 5, 6, and 7 corresponding to the location of parent fluorophore substituents R1-7. The initial ethenyl substituents Xm, Ym, and Zm, which may be the same or different, are halogen, alkyl (containing 1-10 carbon atoms), cyano, ester, amide, ethenyl or polyethenyl, aryl or heteroaryl. The non-ethenyl substituents, which may be the same or different, are hydrogen, halogen, alkyl (containing 1-18 carbon atoms), aryl, arylalkyl, heteroaryl, acyl or sulfo.
