The chemical substance corresponding to 2% 2C2% 27% 2C2% 27 - benzene - 1% 2C3% 2C5 - triyltris% 281 - phenyl - 1H - benzimidazole% 29 has a rather complex structure. This substance is composed of a benzene ring as the core skeleton, and is connected to a specific group at the 1st, 3rd, and 5th positions of the benzene ring. The linked group is 1 - phenyl - 1H - benzimidazole, and is connected by three such groups through the benzene ring.
Specifically, above the benzene ring, at each of the three specific positions, there is a structural unit formed by connecting a benzimidazole ring to a phenyl group. The benzimidazole ring itself is formed by fusing a benzene ring with an imidazole ring, which is a five-membered heterocycle containing two nitrogen atoms. A phenyl group is attached to the 1 position of the benzimidazole ring, so three such 1-phenyl-1H-benzimidazole structural units are connected through the 1, 3, and 5 positions of the benzene ring to form the chemical structure of this complex compound.

2% 2C2% 27% 2C2% 27% 27 - benzene - 1% 2C3% 2C5 - triyltris% 281 - phenyl - 1H - benzimidazole% 29, this is an organic compound. It has many important physical properties, and there are many similarities with the characteristics of all things in "Tiangong Kaiwu".
When it comes to appearance, this compound is often in a solid state, with significant crystalline properties. Just like the description in "Tiangong Kaiwu" of many minerals and metals showing specific morphologies after smelting and other processes, the crystalline morphology of this compound is also determined by its molecular structure and internal forces. The interaction between molecules is exquisite, so that under suitable conditions, it can be arranged in order to form regular crystals.
In terms of solubility, in common organic solvents, such as dichloromethane, chloroform, etc., it exhibits certain solubility characteristics. This property is similar to the fusion of different substances in a specific medium mentioned in "Tiangong Kaiwu". Its solubility is closely related to the polarity of the molecule. The molecular structure of the compound contains both non-polar parts such as benzene rings and nitrogen atoms with a certain polarity in the benzimidazole structure, making it suitable for solubility in organic solvents with moderate polarity and non-polarity.
Thermal stability is quite considerable. When heated, it needs to reach a higher temperature before decomposition and other changes occur. Like the refractory materials and other substances recorded in "Tiangong Kaiwu", it can still maintain certain properties in high temperature environments. This is due to the strong chemical bond force in the molecule, the chemical bond between the benzene ring and the benzimidazole structure is stable, and the conjugate system of the benzimidazole ring itself also enhances the molecular stability, so that the compound can withstand a certain degree of high temperature.
The optical properties cannot be ignored. Because its molecular structure is rich in conjugated systems, it can exhibit fluorescence under specific wavelengths of light. This fluorescence property is similar to the description of the unique optical effects of some special substances in Tiangong Kaiwu, such as some ores emitting strange brilliance under specific light. The electron energy in the conjugated system transitions after absorbing the energy of photons, and then releases the energy in the form of light, thereby generating fluorescence.

2% 2C2% 27% 2C2% 27% 27 - benzene - 1% 2C3% 2C5 - triyltris% 281 - phenyl - 1H - benzimidazole% 29 that is, 2,2 ', 2' - benzene - 1,3,5 - trimethyl tris (1 - phenyl - 1H - benzimidazole), the preparation method of this substance is as follows:
First, the raw materials need to be prepared. The main materials are compounds containing benzene ring and benzimidazole structure, supplemented by suitable solvents, catalysts, etc. < Br >
In a clean reactor, add a benzene ring-containing polyhalogenate and a 1-phenyl-1H-benzimidazole derivative according to an accurate stoichiometric ratio. The proportion of the material to be added is related to the purity and yield of the product, and must be strictly controlled.
Then, inject an appropriate amount of organic solvent, such as N, N-dimethylformamide (DMF) or toluene, etc., to fully dissolve the reactants and form a homogeneous reaction system, which is conducive to effective collision and reaction between molecules.
Furthermore, add specific catalysts, such as palladium catalysts or copper catalysts. The catalyst can reduce the activation energy of the reaction and accelerate the reaction process. However, the amount of the catalyst needs to be carefully controlled. Too much or too little will affect the reaction effect.
Then, the reactor is sealed and the reaction is carried out according to the set reaction temperature and time. The temperature is mostly controlled between 100-150 ° C. This temperature range can not only promote the smooth occurrence of the reaction, but also avoid the excessive generation of side reactions. The reaction time is about 12-24 hours, during which continuous stirring is required to ensure that the reactants are mixed evenly and the reaction is sufficient.
After the reaction is completed, the reaction mixture is cooled to room temperature, and the product is separated and purified by appropriate separation means, such as extraction, filtration, column chromatography, etc. An organic solvent with a large solubility difference from the product can be selected for extraction, and the product can be extracted from the reaction system; insoluble impurities can be removed by filtration; column chromatography can further achieve high purification of the product according to the distribution coefficients of the product and impurities between the stationary phase and the mobile phase.
After this series of steps, 2,2 ', 2' -benzene-1,3,5-tribasic (1-phenyl-1H-benzimidazole) can be obtained. The whole preparation process requires high purity of raw materials, reaction conditions and separation and purification operations, so that high purity target products can be obtained.

2% 2C2% 27% 2C2% 27% 27 - benzene - 1% 2C3% 2C5 - triyltris% 281 - phenyl - 1H - benzimidazole% 29 is an organic compound, and its stability is related to many aspects.
In terms of structure, this compound contains a benzene ring and a benzimidazole structure. The structure of the benzene ring is extremely stable. Its conjugate system delocalizes the electron cloud, reduces the molecular energy and increases its stability. The benzimidazole ring also has a conjugate system, and the two are connected to consolidate the overall structure. The three benzimidazole groups on the central benzene ring are connected in a specific position, and the spatial arrangement affects the stability. If the steric resistance is suitable, the groups coordinate with each other, and the stability can be increased; if the steric resistance is too large, the tension will be generated in the molecule, and the stability will decrease.
From the perspective of chemical bonds, the covalent bonds such as carbon-carbon bonds and carbon-nitrogen bonds in the compound have a certain bond energy. The higher the bond energy, the more stable the bond, and the more stable the compound is. The bond energy of various chemical bonds in this compound ensures that its structure is stable under general conditions and is not easy to decompose.
The external environment has a great influence on its stability. When the temperature rises, the thermal motion of the molecule intensifies. When the energy is sufficient to overcome the intermolecular forces and chemical bond energy, the stability of the compound is affected, or reactions such as decomposition and rearrangement occur. In different solvents, the interaction between the solvent and the compound molecules is different. If the solvent and the compound form hydrogen bonds, van der Waals forces, etc., interact, or change its stability. In case of strong acids and bases, some chemical bonds in the compound may break, because acid and base can catalyze specific reactions and affect their stability.
Light is also an important factor. If the compound absorbs light of a specific wavelength, the photon energy or intra-molecular electron transition causes the molecule to be in an excited state, and the excited state has high molecular activity, which is prone to reactions and reduces stability.
