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