Abstract:
A fluorescent group-containing carbodiimide compound, having a chemical structure with an ester linkage, represented by the general formula (1):Y1â€”N&boxH;C&boxH;Nâ€”Y2â€”Qâ€”Y3â€”Fâ€ƒâ€ƒ(1) whereineach of Y1, Y2, and Y3 is a functional group selected from the group consisting of â€”CH2â€”, â€”NHCOâ€”, â€”CONHâ€”, â€”Oâ€”, â€”Sâ€”, â€”NR1â€” (R1 is a straight-chain, circular, or branched saturated or unsaturated aliphatic hydrocarbon group having from 1 to 20 carbon atoms), â€”NR2R3â€” (R2 and R3 are independently a hydrogen atom, a straight-chain, circular or branched saturated or unsaturated aliphatic hydrocarbon group having from 1 to 20 carbon atoms, or a cycloalkyl group, an aryl group, or an aralkyl group, each of which may have a substituent, or if either R2 or R3 is a hydrogen atom, then the remainder is a straight-chain, circular, or branched saturated or unsaturated aliphatic hydrocarbon group having from 1 to 20 carbon atoms, or a cycloalkyl group, an aryl group, or an aralkyl group, each of which may have a substituent, and furthermore, R2 and R3 may be coupled together to form a nitrogen-containing heterocyclic group which may have an oxygen as a whole), â€”COOâ€”, â€”OCOâ€”, â€”NHSO2â€”, â€”NHC(S)NHâ€”, â€”SO2NHâ€”, and other functional groups selected from the functional groups represented by the general formula (2): â€”(CH2)pâ€”(L)râ€”(CH2)qâ€”â€ƒâ€ƒ(2) â€ƒ(where L is a functional group selected from the group consisting of â€”CH2â€”, â€”NHCOâ€”, â€”CONHâ€”, â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”NR2R3â€”, â€”COOâ€”, â€”OCOâ€”, â€”NHSO2â€”, â€”NHC(S)NHâ€”, and â€”SO2NHâ€”; each of p and q is one of integers of from 0 to 20, while r is zero (0) or one (1), and R1, R2, and R3 are same as those of the general formula (1)); Q is an ester linkage; and F is a fluorescent group made of a cyanine dye represented by one of the general formulas (3-1), (3-2), and (3-3), â€ƒ(where m is one of integers of from 1 to 3, while n is one (1), each of J1, J2, J3, and J4 is a functional group independently selected from the group consisting of H, OH, COOH, a sulfonic group, a sulfonate group, and an ester, amide, ether, alkyl, alkane, alkene, alkyne, allyl, and amino groups, and J1 and J2 are different functional groups) where each of the functional groups represented by Y1, Y2, Y3, and F may have a group selected from the group consisting of carboxyl groups, sulfonyl groups, and phosphonyl groups, which are substituted with alkali metals, alkaline earth metals, or basic groups containing nitrogen or phosphorus, respectively, and also Y1, Y2, and Y3 may be the same functional group or different functional groups.
