Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a class of asymmetric benzoxanthene dye useful as a fluorescent dyes. SOLUTION: The asymmetric benzoxanthene dye compound has a structure represented by formula (A), wherein Y1and Y2are each independently hydroxy, oxygen, iminium or amine, R1to R8are each independently hydrogen, fluorine, chlorine, a lower alkyl, lower alkene, lower alkyne, sulfonate, amino, ammonium, amide, nitrile, alkoxy, a linking group or a combination of them, R9is acetylene, an alkane, alkene, cyano, substituted phenyl or a combination of them, and the substituted phenyl has a structure represented by formula (B), wherein X1is a carboxylic acid or a sulfonic acid, and X2and X5are independently, hydrogen, chlorine, fluorine, or a lower alkyl, and X3and X4are independently hydrogen, chlorine, fluorine, a lower alkyl, carboxylic acid, sulfonic acid or linking group.
