Most of water-soluble cyanine dyes have -SO3H and –COOH in their molecules, which will influence the biomolecules' functional characters. A new kind of water-soluble cyanine dyes with several cations in molecules were designed and synthesized, preparation conditions of intermediate and dyes were researched and optimized, the yield of dye is 25%. The novel kind of cyanine dye are water-soluble , spectrum characters was researched , all the dyes were charactered by 1H NMR and TOF-MS, spectrum in different solvent of novel dyes were focused on, one of the kind dyes show higher fluorescence quantum yield than the result reported. Because of several cations in the structure, it is promising when used in DNA assay and other bio-assay field.
