Looking at its structure, it is composed of several parts cleverly connected. The first part contains a 4- (diethylamino) phenyl group. In this phenyl group, the benzene ring acts as a stable skeleton, and the diethylamino group is connected to the fourth position of the benzene ring. The nitrogen atom in the amino group has a solitary pair of electrons, which can participate in a variety of chemical reactions and affect the electron cloud distribution and chemical activity of the compound.
The sub-part is 4- (diethylimino) cyclohexane-2,5-diene-1-subunit methyl. In this part, the cyclohexadiene structure endows the compound with a special conjugate system, which affects its optical and electronic properties. The diethyleneimide group is connected to the fourth position of cyclohexadiene, which changes the electron cloud density of this part. Methylene connects this part to the 4- (diethylamino) phenyl group, which becomes a bridge connecting the two key structures.
Furthermore, the compound contains benzene-1,4-disulfonic acid group. The sulfonic acid group has strong hydrophilicity, which can make the compound soluble in water to a certain extent, and the sulfonate negative ion is stable, which plays an important role in the overall charge distribution and chemical stability of the compound. Two sulfonic acid groups are connected to the 1,4 positions of the benzene ring, which further affects the spatial structure and chemical activity of the compound.
The interaction of various parts in the structure of this compound determines its physical and chemical properties, and may have potential applications in materials science, chemistry research and other fields.

2-% {[4- (Diethylamino) Phenyl] [4- (Diethyliminio) Cyclohexa-2,5-Dien-1-Ylidene] Methyl} Benzene-1,4-Disulfonate is an organic compound. Its physical properties are quite critical, and it is related to its application in various fields.
Looking at its morphology, under room temperature and pressure, this compound is mostly in a solid state. If you look closely at its appearance, it is usually crystalline, with a regular and orderly crystal structure and a certain luster. The formation of this morphology is due to the interaction between molecules, such as hydrogen bonds, Van der Waals forces, etc., which make the molecules arranged in an orderly manner.
Solubility is also an important physical property. This compound exhibits some solubility in polar solvents, such as water. Due to the fact that its molecular structure contains sulfonic acid radical groups, this group is hydrophilic and can form hydrogen bonds with water molecules, thereby improving its solubility in water. However, in non-polar solvents, such as hexane, the solubility is poor, due to the weak force between the non-polar solvent and the compound.
Melting point is also a property that cannot be ignored. The compound has a specific melting point. When heated to a certain temperature, the molecule obtains enough energy to overcome the lattice energy, the crystal structure disintegrates and converts to a liquid state. This melting point value is specific and can be used as an important indicator to identify the purity of the compound. If the compound has high purity, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point decreases and the melting range becomes wider.
Furthermore, its density is fixed under specific conditions. Density reflects the mass of a substance per unit volume and is related to its molecular structure and packing method. The density of this compound can assist in determining its position and distribution in the mixture, and is of great significance in operations such as separation and purification.
The dispersive properties of this compound also need attention. Because its molecular structure contains a conjugated system, it will absorb and emit light of a specific frequency and exhibit a specific color under the irradiation of a specific wavelength of light. This property may have potential applications in optical materials, dyes and other fields.

To prepare 2 - {[4- (diethylamino) phenyl] [4- (diethylamino) cyclohexyl-2,5-diene-1-subunit] methyl} benzene-1,4-disulfonate, the method is as follows:
First take an appropriate amount of 4- (diethylamino) benzaldehyde and 4-methylbenzene-1,2-disulfonic acid and place them in a suitable reaction vessel. Add an appropriate amount of organic solvent, such as ethanol or dichloromethane, and mix them thoroughly to build a homogeneous reaction environment.
Slowly add an alkali catalyst, such as potassium carbonate or sodium carbonate, and the dosage needs to be precisely controlled to promote the reaction. During this process, the reaction temperature needs to be closely monitored, generally maintained between 50 and 80 degrees Celsius. This temperature control goal can be achieved with the help of an oil or water bath device. During the reaction, the molecules interact and undergo complex chemical changes. The aldehyde group binds to the active check point on the benzene ring, and the sulfonic acid group also participates in it to gradually build the basic structure of the target molecule.
After the reaction is completed, the organic solvent is removed by a rotary evaporator to obtain a crude product. Then purified by column chromatography or recrystallization. In column chromatography, silica gel is selected as the stationary phase, and a suitable eluent is prepared to separate impurities from the target product; for recrystallization, a suitable solvent, such as ethanol-water mixed solvent, is selected, heated to dissolve the crude product, and after cooling, the target product is crystallized and precipitated, filtered and dried, and finally a pure 2- {[4- (diethylamino) phenyl] [4- (diethylamino) cyclohexene-2,5-diene-1-subunit] methyl} benzene-1,4-disulfonate product. The whole process requires fine operation, attention to the control of reaction conditions and the purification of the product, in order to obtain satisfactory results.
