Abstract:
A fluorescent group-containing carbodiimide compound having at least one group selected from a carboxyl group, a sulfo group, a phosphono group and a phospho group which have substitution of an alkali metal, an alkaline earth metal or a basic group containing a nitrogen or phosphorus atom, which is represented by the following general formula (III): wherein,X represents a halogen atom or a sulfonic acid group; A represents a functional group selected from the group consisting of â€”CH2â€”, â€”NHCOâ€”, â€”CONHâ€”, â€”Oâ€”, â€”Sâ€”, â€”NR1â€” wherein R1 represents a linear, cyclic or branched saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms, â€”NR2R3â€” wherein R2 and R3 each independently represent a hydrogen atom, a linear or branched saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms, or a cycloalkyl group, an aryl group or an aralkyl group which may have a substituent, provided that when one of R2 and R3 is a hydrogen atom, the other represents a linear or branched saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms, or a cycloalkyl group, an aryl group or an aralkyl group which may have a substituent, or R2 and R3 may be bonded to each other to form as a whole a nitrogen-containing heterocyclic group which may contain an oxygen atom, â€”COOâ€”, â€”OCOâ€”, â€”NHSO2â€”, â€”NHC(S)NHâ€” and SO2NHâ€”; n represents 0 or 1; W represents a direct bond or a quaternary onium group; Y1, Y2, Y3 and Y4 each represent a functional group represented by the general formula (II): â€”(CH2)pâ€”(L)râ€”(CH2)qâ€”â€ƒâ€ƒ(II) â€ƒwherein, L represents a functional group selected from the group consisting of â€”CH2â€”, â€”NHCOâ€”, â€”CONHâ€”, â€”Oâ€”, â€”Sâ€”, â€”NR1â€”; p and q each represent an integer of from 0 to 20; and r represents the integers 0 or 1; B represents a hydrogen atom or a monovalent organic group being the same as or different from â€”Wâ€”Y1â€”[A]nâ€”Y4; and F represents a fluorescent group; Q represents either a tertiary or quaternary nitrogen atom, or a tertiary or quaternary phosphorus atom; R4 and R5 each independently represent a hydrogen atom, a linear or branched saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms, or a cycloalkyl group, an aryl group or an aralkyl group which may contain a substituent, provided that when one of R4 and R5 is a hydrogen atom, the other represents a linear or branched saturated or unsaturated aliphatic hydrocarbon group having 1-20 carbon atoms, or a cycloalkyl group, an aryl group or an aralkyl group which may contain a substituent, or R4 and R5 may be bonded to each other to form a nitrogen-containing heterocyclic group or a phosphorus-contain heterocyclic group, which may contain an oxygen atom, as Q+R4R5â€”; Y5 has the same meaning as defined for Y1, Y2, Y3 and Y4; and at least one functional group selected from B, Y1, Y2, Y3, Y4, Y5, A, W, R4, R5 and F has at least one group selected from a carboxyl group, a sulfo group, a phosphono group and a phospho group which have substitution of an alkali metal, an alkaline earth metal or a basic group containing a nitrogen or phosphorous atom.
