Synthetic example 1

[0344] (1) Synthesis Example 1: Synthesis of [Chemical Formula I]

[0345]

[0346] After dissolving 0.01 mol (7.8 g) of the compound of [Chemical formula 1-5] in 50 g of MeOH, 0.011 mol of lithium bistrifluoromethanesulfonimide was added as a 20% aqueous solution to replace the salt. After filtration, the obtained compound was dissolved in chloroform, washed with water, and concentrated under reduced pressure to obtain 0.009 mol and 9.2 g of [Chemical Formula I] (90% yield).

[0347] Ionization mode: APCI+: m / z=740[M+H]+, exact mass (Exact Mass): 740

Synthetic example 2

[0348] (2) Synthesis Example 2: Synthesis of [Chemical Formula II]

[0349]

[0350] By adding 0.01 mol and 7.7 g of the compound of [Chemical formula 1-6], 0.008 mol and 10.2 g of [Chemical formula II] were obtained by the method similar to that of Synthesis Example 1 (yield 80%).

[0351] Ionization mode: APCI+: m / z=741[M+H]+, exact mass (Exact Mass): 741

Synthetic example 3

[0352] (3) Synthesis Example 3: Synthesis of [Chemical Formula III]

[0353]

[0354] Added 0.01 mol, 6.7 g of the compound of [Chemical formula 1-7] and produced it by the method similar to the synthesis example 1, and obtained [Chemical formula III] 0.0082 mol, 7.5 g (yield 82%).

[0355] Ionization mode: APCI+: m / z=630[M+H]+, exact mass (Exact Mass): 630

[0356] 3. Synthesis of Triarylmethane Polymer Compounds

[0357]

[0358] (Synthesis Example 1) Synthesis of Compound A

[0359] A reflux cooling device is installed in a 50mL flask, and under nitrogen atmospheric pressure, based on the total weight of the compound produced, benzophenone methacrylate, methacrylic acid represented by the chemical formula A-1 structure, and methacrylic acid represented by the chemical formula I 5, 20, and 75% by weight of the dyes were added, mixed with a 1:1 mixture of solvent propylene glycol monomethyl ether acetate and diacetone alcohol, and heated to 60°C. Then, based on the t...

Description

technical field [0001] This application claims the priority of Korean Patent Application No. 10-2018-0106491 filed with the Korean Patent Office on September 06, 2018, the entire contents of which are included in this specification. [0002] This specification relates to a compound, a colorant composition, a photosensitive material, a color filter, and a display device. Background technique [0003] Currently, in order to realize a color filter, a pigment dispersion method using a pigment as a colorant is generally applied. However, in the case of pigment dispersions, not only the pigments exist in a particle state to scatter light, but also the surface area of ​​the pigments increases sharply due to the miniaturization of the pigments, and non-uniform particles are formed due to the deterioration of the dispersion stability caused by this. Pigment particles. Therefore, in order to realize the high brightness, high contrast, and high resolution required in recent years, a ...
