摘要
Indolyl-benzoxazole benzoxazole, benzothiazole, benzoselenazole, benzimidazole, quinoline or 3,3-dimethyl indole mono-, tri-, penta- and hepta-methin cyanine dyes (I) are new. Indolyl-benzoxazole benzoxazole, benzothiazole, benzoselenazole, benzimidazole, quinoline or 3,3-dimethylindole mono-, tri-, penta- and hepta-methin cyanine dyes of formula (I) are new: R1-6 = substituents; at least one of R1, R2 and R3 = indolyl; X = oxygen (O), sulfur (S), selenium (Se), imino (NR9), ethylene (CH=CH) or dimethyl methylene (C(CH3)2); R9 = optionally substituted alkyl; R7, R8 = alkyl, sulfoalkyl, carboxyalkyl or a group of the formula -(CH2)l-SO2-Y-SO2-alkyl, -(CH2)l-SO2-Y-CO-alkyl, -(CH2)l-CO-Y-SO2-alkyl, -(CH2)l-CO-Y-O-alkyl, -(CH2)l-NH-SO3-, -(CH2)l-N(alkyl)-SO3- or -(CH2)k-N(aryl)-SO3-; l = 1-6; Y = NH or N; n = 1, 3, 5 or 7; L = an optionally substituted methin group, which may be part of carbocyclic ring(s); M = a counterion to balance the charge if necessary.
