This compound belongs to a relatively complex organic compound and may appear in solid form in appearance. From the perspective of melting point, due to the presence of multiple conjugated systems and polar functional groups in its molecular structure, the intermolecular force will be enhanced, and the melting point is expected to be relatively high. The boiling point will also be higher due to strong intermolecular interactions, and the phase transition will occur under heating conditions.
In terms of solubility, since the molecule contains ethoxy, a group with certain lipophilic properties, and there are polar groups such as sulfone and carbonyl, the solubility in organic solvents will show certain characteristics. In polar organic solvents such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), the substance may have good solubility due to the interaction between polar groups and solvent molecules; however, in non-polar organic solvents such as n-hexane and cyclohexane, the solubility may be poor, because it is difficult for non-polar solvents to form effective interactions with polar parts of the molecule. < Br >
In terms of density, due to its relatively compact molecular structure, dense atomic arrangement, and containing relatively large atoms such as sulfur and oxygen, the density may be greater than that of some common organic solvents.
In terms of stability, the conjugate structure in the molecule makes it stable to a certain extent, but at the same time, functional groups such as carbonyl groups have certain reactivity. Under specific conditions, such as in the presence of strong acids, strong bases or strong oxidants, chemical reactions may occur, resulting in structural changes.
The physical properties of this compound are determined by its unique molecular structure. In practical applications and research, these properties have important reference value for its separation, purification, and selection of conditions for participating in chemical reactions.

2% 2C9 -bis (4-ethoxyphenyl) sulfono [2% 2C1% 2C9 - def: 6% 2C5% 2C10 - d'e'f '] diisobenzo - 1% 2C3% 2C8% 2C10 - (2H% 2C9H) -tetraone This compound has the following chemical properties:
The structure of this compound contains multiple phenyl rings and a special sulfone diisobenzotetraone structure, which endows it with certain rigidity and stability. Due to the existence of ethoxy groups, the molecule has certain lipophilicity.
From the perspective of electronic effects, the benzene ring is an electron-rich system, and the sulfone group is a strong electron-absorbing group. This electron distribution affects the reactivity of the molecule. The strong electron-absorbing action of the sulfone group can reduce the electron cloud density on the benzene ring, so that the activity of the electrophilic substitution reaction of the benzene ring is relatively reduced; and when the nucleophilic substitution reaction is carried out, the sulfone group can activate the ortho-para-sites, making it easier for the nucleophilic reagents to attack these positions.
The compound conjugated system is large and has certain photophysical properties. Under light conditions, the intra-molecular electrons can transition and may exhibit properties such as fluorescence. Due to the existence of the conjugated system, its ultraviolet absorption spectrum will also have specific absorption peaks, which can be used for qualitative and quantitative analysis.
In addition, there are multiple carbonyl groups in this compound. Carbonyl groups are polar groups, which make the molecule have a certain dipole moment, which affects the intermolecular forces and has important effects on its solubility, melting point, boiling point and other physical properties. Under appropriate conditions, carbonyl groups can undergo reactions such as nucleophilic addition, such as condensation with alcohols to form derivatives such as ketals.

First take an appropriate amount of starting materials and react under specific reaction conditions. Usually use reagents with specific activities under suitable temperature and pressure environment to make them interact.
At the beginning of the reaction, mix phenyl compounds containing ethoxy groups with anthracene and related parent structures according to specific molar ratios. Place in a special reaction vessel, which must be able to withstand the temperature and pressure changes required for the reaction. < Br >
Next, add an appropriate amount of catalyst. The choice of this catalyst is crucial, it needs to be able to effectively promote the progress of the reaction, and has a high degree of influence on the selectivity of the target product. During the reaction process, the change of temperature is closely monitored, and it is generally maintained in a specific temperature range, such as [specific temperature range], because the temperature has a great influence on the reaction rate and product formation.
The pressure of the reaction system also needs to be properly controlled and maintained at a certain stable value to ensure the smooth progress of the reaction. After a certain period of time, the reaction is gradually completed.
After the reaction is completed, suitable separation and purification methods are used. Chromatography, recrystallization, etc. are often used to remove impurities in the reaction system to obtain the pure target product 2,9-bis (4-ethoxyphenyl) anthrano [2,1,9-def: 6,5,10-d'e'f '] diisobenzofuran-1,3,8,10 - (2H, 9H) -tetraketone. This process requires fine operation to obtain high-purity products to meet the needs of subsequent applications.

Today, there is a product name "2,9-bis (4-ethoxyphenyl) fluoreno [2,1,9-def: 6,5,10-d'e'f '] diisobenzofuran-1,3,8,10 - (2H, 9H) -tetraketone". What is the price on the market? This is a more complex organic compound in the field of fine chemicals. However, its price in the market is difficult to determine.
Because of many factors, its price fluctuates. First and foremost, the difficulty of production. If the synthesis of this compound requires complicated steps, strict reaction conditions, or extremely high requirements for the purity of the raw material, and the raw material is rare, the production cost will be high, and the price will rise.
Furthermore, the supply and demand relationship in the market has a great impact. If the demand for this compound in a certain industry such as photovoltaic materials surges and the supply is limited, its price will rise; on the contrary, if the demand is low and there is too much production, the price will easily decline.
In addition, the quality produced by different manufacturers may be different, which will also make the price different. Those who are skilled in the process and have high product purity may have higher prices than ordinary manufacturers.
However, after checking all kinds of ancient books, it is difficult to obtain the relevant records of this compound. It is difficult to determine its exact price based on the ancient books. Today's market conditions are unpredictable. To know its price, you need to check the chemical product trading platform and consult the industry merchants in order to obtain more accurate price information.
