    • This invention provides cyclic-bridged dyes, particularly cyclic-bridged cyanine dyes, of the general formula: In this formula, each dotted line represents carbon atoms necessary to form a fused substituted or unsubstituted aromatic ring; n=1-18; m=1-18, selected independently from n. X and Y are selected independently from the group consisting of S, O, N, CH2 and C(CH3)2; at least one of said R1 and R2 comprises a sulfonic acid or sulfonate group attached to the aromatic ring; and R3 and R4 are independently selected from the group consisting of carboxyl, activated carboxyl and methyl, wherein at least one of said R3 and R4 groups is carboxylate or activated carboxylate. Methods of making and using the cyclic-bridged dyes are also provided.
    • 本发明提供了具有以下通式的环状桥联染料,特别是环状花青染料:在该式中,每个虚线表示形成稠合取代或未取代的芳环所需的碳原子; n = 1-18; m = 1-18,独立于n。 X和Y独立地选自S,O,N,CH 2和C(CH 3)2; 所述R 1和R 2中的至少一个包含连接到所述芳香环上的磺酸基或磺酸基; 并且R 3和R 4独立地选自羧基,活化的羧基和甲基,其中所述R 3和R 4基团中的至少一个是羧酸酯或活化的羧酸酯。 还提供了制备和使用环状桥连染料的方法。
