What are the main uses of 2-octadecyl-1H-thioxantheno [2,1,9-def] isoquinoline-1,3 (2H) -dione?

2 - octadecyl - 1H - thioxantheno [2,1,9 - def] isoquinoline - 1,3 (2H) -dione is a chemical substance. The use of this substance is rarely seen in traditional books. I will deduce it with modern chemical knowledge.

In the field of materials science, it may be useful. First, because of its unique molecular structure, it can be used as an additive for high-performance materials. If added to polymer materials, this substance may change its properties. Polymer materials often need to be toughened and strengthened. The long-chain alkyl group of this compound, that is, the 2-octadecyl part, can be inserted into the polymer chain to increase the distance between the chains, reduce the intermolecular force, and increase the flexibility of the material; while thioxantheno and isoquinoline-dione structures have rigid and conjugated systems, or can increase the mechanical strength and thermal stability of the material, opening up new paths for material processing and application.

In the field of biomedicine, there is also potential. Its complex structure or specific biological activity. From the perspective of drug development, it may be used as a lead compound. After structural modification and optimization, targeted drugs may be obtained. For example, on tumor cells, or by virtue of their structural characteristics, they can precisely act on specific targets of cancer cells, interfere with the growth and proliferation of cancer cells, and provide new ideas for the research and development of anti-cancer drugs; or in the field of antibacterial, with their special chemical structure, they can break the bacterial cell wall or cell membrane, inhibit the growth of bacteria, and open up new avenues for the creation of antibacterial drugs.

However, this is based on the speculation of modern chemical theory and research trends. There is no ancient literature to test its exact use, which is for exploration and reference only.

What are the physical properties of 2-octadecyl-1H-thioxantheno [2,1,9-def] isoquinoline-1,3 (2H) -dione?

The physical properties of 2-octadecyl-1H-thioanthrano [2,1,9-def] isoquinoline-1,3 (2H) -dione are as follows.

The color state of this substance may be solid at room temperature, or it may have a specific crystalline form. This is due to the orderly arrangement of molecular structures. The melting point is either due to the interaction of long-chain alkyl groups with complex cyclic structures, resulting in increased intermolecular forces, and the melting point may be at a specific temperature range. In terms of boiling point, considering the relative mass of the molecule and the existence of strong intermolecular forces, the boiling point is also quite high.

Solubility is one of the important physical properties. In organic solvents, due to the presence of non-polar long-chain alkyl groups in the molecule, in non-polar or weakly polar organic solvents, such as benzene, toluene, etc., there may be a certain solubility. Due to the principle of "similar miscibility", the non-polar part and the non-polar molecules of the organic solvent attract each other. However, in polar solvents, such as water, due to the limited polarity of the molecule as a whole, and the long-chain alkyl groups hinder the formation of hydrogen bonds with water molecules, the solubility is very small.

The density of the substance is related to the compactness of the molecule. Due to the complex molecular structure and heavy atoms, the density of the substance may be higher than that of the common light organic solvent. Compared with water, or depending on the specific structural characteristics, it presents a density greater than or less than that of water.

In addition Due to the existence of conjugated systems and complex cyclic structures in the molecular structure, it has a specific impact on light propagation, and the refractive index may be different from that of common organic compounds, reflecting the uniqueness of the molecule's effect on light. These physical properties are determined by its unique molecular structure, and are of great significance in the study of its separation, purification, and application.

To prepare 2-octadecyl-1H-thioanthrano [2,1,9-def] isoquinoline-1,3 (2H) -dione, the method is as follows:
First, thioanthracene is used as a base, in a suitable solvent, such as aprotic organic solvent dichloromethane or N, N-dimethylformamide, and a suitable base, such as potassium carbonate or triethylamine, is added to assist the reaction. Then, a halogenated hydrocarbon containing octadecyl groups, such as octadecyl bromide, is slowly added, heated and stirred, so that it undergoes a nucleophilic substitution reaction. The purpose of this step is to introduce octadecyl into a specific position of thioanthracene. When the reaction duration is about a few, the reaction progress needs to be closely monitored, which can be observed by thin-layer chromatography.
After the first step of reaction is completed, the product is moderately treated to remove impurities, such as through conventional steps such as extraction, washing, and drying. Subsequently, this intermediate product is transferred to another reaction system, and a reagent capable of interacting with thioanthracene at a specific position is added to construct the isoquinoline-1,3 (2H) -dione structure. For example, compounds containing nitrogen and carbonyl groups with appropriate activity can be introduced, and under the catalysis of suitable catalysts, such as organometallic catalysts or Lewis acid, the cyclization reaction can be promoted at a specific temperature and reaction time to form the target structure.
After the reaction is completed, the pure 2-octadecyl-1H-thioanthrano [2,1,9-def] isoquinoline-1,3 (2H) -dione can be obtained by fine purification methods such as column chromatography or recrystallization. In this process, the reaction conditions of each step need to be carefully controlled, such as temperature, proportion of reactants, reaction time, etc., and the yield may be reduced or the impurity product may be obtained. However, according to this step-by-step method and careful operation, this compound can be obtained.
