Embodiment

[0146] Hereinafter, an Example and a comparative example are given, and the characteristics of this invention are demonstrated more concretely. Unless departing from the gist of the present invention, the materials, usage amounts, ratios, processing contents, processing procedures, and the like shown in the following examples can be appropriately changed. Therefore, the scope of the present invention should not be limitedly interpreted by the specific examples shown below.

[0147]

Synthetic example 1

[0148] Synthesis example 1 (compound c3):

[0149] 150 mL of toluene, 125 mL of ethanol, and 100 mL of acetic acid were added to 26.6 g of 4,5-dimethyl-1,2-phenylenediamine and 35.6 g of ninhydrin, and reacted at 70° C. for 3 hours. After cooling the reaction solution to room temperature, the precipitated crystals were collected by filtration, washed with ethanol, and dried to obtain 47 g of intermediate c2A.

[0150] 1 H-NMR (300MHz, CDCl 3 ): δ2.49ppm(s,3H), 2.51ppm(s,3H), 7.52-7.58ppm(t,1H), 7.71-7.76ppm(t,1H), 7.85-7.95ppm(m,3H), 8.02 -8.08ppm(d,1H)

[0151] 22 g of intermediate c2A and 32 g of phenol were dissolved in 20 mL of methanesulfonic acid and 20 mL of acetonitrile. The reaction solution was heated, and 0.3 mL of 3-mercaptopropionic acid was added dropwise while maintaining 90°C. After stirring for 3 hours, 200 mL of acetonitrile and 100 mL of water were added, and the reaction solution was stirred at 40° C. for 2 hours. The precipitated crystals were collec...

Synthetic example 2

[0153] Synthesis example 2 (compound c1):

[0154] Except having changed 4, 5- dimethyl- 1, 2- phenylenediamine into o-phenylenediamine, 28 g of compound c1 were obtained by the method similar to synthesis|combination of compound c3.

[0155] 1 H-NMR (300MHz, DMSO-d 6 ): δ6.61-6.68ppm(d,4H), 6.95-7.01ppm(d,4H), 7.50-7.70ppm(m,3H), 7.72-7.90ppm(m,2H), 8.00-8.08ppm(d ,1H), 8.12-8.25ppm(m,2H), 9.41ppm(bs,2H)

Abstract

Provided as a material able to produce an optical member, such as a lens having a high light transmittance, is a solvate of a compound represented by general formula 1, wherein the solvent contains a nitrogen atom-containing organic compound having a molecular weight of 200 or less and the value obtained by dividing the number of carbon atoms in the nitrogen atom-containing organic compound by the sum of the number of nitrogen atoms and the number of oxygen atoms is 5 or less. In the formula, X and Y each independently denote a heteroatom or a carbon atom, but at least one of X and Y is a nitrogen atom, Z denotes an atom group which forms a 5- to 7-membered ring together with X-C=C-Y and includes at least one type of atom selected from between a carbon atom and a heteroatom, R3 to R6 denote substituent groups, q and r are integers between 0 and 4, v is an integer between 0 and 4, and w is an integer of 0 or greater.

Description

technical field [0001] The invention relates to a solvate and a method for producing the solvate. Background technique [0002] Glass materials have long been used for optical components in camera modules such as cameras, video cameras or mobile phones with cameras, video phones or video doorbells. Glass materials are preferably used because they have various optical properties and are excellent in environmental resistance, but have the disadvantages that weight reduction and miniaturization are difficult, and processability and productivity are poor. In contrast, cured resins can be mass-produced and have excellent workability, so they are being used in various optical components. [0003] In recent years, along with miniaturization of camera modules, optical components used in camera modules have been required to be miniaturized. However, if optical components are miniaturized, a problem of chromatic aberration will arise. Therefore, in optical components using cured res...
