Embodiment 1
[0085] Example 1. Preparation of compound M1
[0086] (1) Add 125.2 parts of commercial dye (II-1) into 500 parts of water and stir to dissolve, then add 13.5 parts of 1,6-hexanedithiol, namely HS(CH 2 ) 6 SH, stir, gradually raise the temperature to 55-60°C, continuously add 20% sodium hydroxide aqueous solution dropwise to maintain the pH 6-7 until the pH is constant at pH 9, at this time the dye precipitates, filter, and dry to obtain 110 parts of derivative M1 -B. The maximum absorption in water is 603nm, mass spectrum m / z(-): 558.0([ M -2H] 2 - / 2]), 1117.1([ M -H] -1 ), 1139.1 ([ M -2H+Na] -1 ), the intermediate dye product (with M=H free sulfonic acid SO 3 H meter) the most abundant accurate molecular mass M for 1118.1.
[0087]
[0088] (2) In 300 parts of xylene, add 100 parts of dimethyl sulfoxide, while stirring, put in 128 parts of blue dye M1-B, 7.5 parts of sodium carbonate, 180 parts of ethyl benzoyl acetate and heat up. Carry out the reaction at 1...
Embodiment 2
[0092] Embodiment 2. preparation compound M3, M4, M5, M6
[0093] By the same method as in Example 1, use 1,2-ethanedithiol, 1,3-propanedithiol, 1,4-butanedithiol, 1,4-benzenedithiol respectively, and use different bases The magenta dyes M3, M4, M5 and M6 with the general structural formula (I-1) are prepared by MOH neutralization and MCl salting out. Linker X and sulfonic acid counterion M are shown in Table 1.

Embodiment 3
[0097] Example 3. Preparation of compound M2
[0098] (1) Add 125.2 parts of C.I. Reactive Blue 19 commercial dye (structural formula II-2) into 500 parts of water and stir to dissolve, then add 13.5 parts of 1,6-hexanedithiol and stir, and gradually heat up to 55-60°C. Add dropwise 20% lithium hydroxide aqueous solution to maintain pH 6-7 until the pH is constant at pH 9, filter, wash the filter cake with 10% lithium chloride aqueous solution, and dry to obtain 112 parts of derivative M2-B. The maximum absorption in water is 603nm, mass spectrum m / z(-): 558.0([ M -2H] 2- / 2]), 1117.1([ M -H] -1 ), 1139.1 ([M -2H+Na] -1 ),. Intermediate dye product M2-B (with free sulfonic acid SO 3 H meter) the most abundant accurate molecular mass number M is 1118.1.
[0099]
[0100] (2) In 300 parts of xylene, add 100 parts of dimethyl sulfoxide, while stirring, put 128 parts of the compound of formula M2-B, 7.5 parts of sodium carbonate, 180 parts of ethyl benzoyl acetate and h...
