First take an appropriate amount of 2-chlorobenzaldehyde and acetophenone, place in a clean reactor, add an appropriate amount of basic catalyst, such as potassium hydroxide or potassium carbonate alcohol solution. At a suitable temperature, often at 60-80 ℃, when stirring the reaction for several times, this step is the condensation reaction of aldol and ketone to generate the corresponding chalcone intermediates. After the reaction is completed, the product is extracted with an appropriate organic solvent, such as ethyl acetate, washed with water, dried, distilled under reduced pressure to remove the solvent, and then purified by recrystallization.
Take an appropriate amount of o-phenylenediamine, and the obtained chalcone intermediate above, put it into a reaction vessel filled with glacial acetic acid in a suitable molar ratio, such as 1:1.2 - 1:1.5, and slowly heat it until refluxed. When maintained for a few days, this is a cyclization condensation reaction to generate the target product 2,2 '-bis (2-chlorophenyl) -4,4', 5,5 '-tetraphenyl-1,1' -imidazole. After the reaction system cools, pour it into a large amount of cold water, solid precipitates, collect it by suction filtration, and wash it alternately with water and ethanol several times to obtain a crude product. Pure 2,2 '-bis (2-chlorophenyl) -4,4', 5,5 '-tetraphenyl-1,1' -biimidazole product can be obtained by column chromatography or recrystallization of the crude product with suitable eluent or solvent, such as petroleum ether and ethyl acetate mixture. Although this synthesis method is complicated, the conditions are easier to control and the yield is acceptable, which is quite commonly used in the field of organic synthesis.

Looking at its appearance, it often takes a solid form due to intermolecular forces. The solid state is convenient for storage and transportation, and also makes related operations more convenient.
In terms of solubility, the compound exhibits a certain solubility in organic solvents. The polarity and molecular structure of the organic solvent interact with the compound, which affects its solubility. This property is crucial in the process of synthesis, separation and purification, and can be effectively treated with the help of suitable organic solvents.
Melting point and boiling point are also important properties. The melting point characterizes the temperature at which a compound changes from a solid state to a liquid state. The melting point of the compound depends on intermolecular forces, such as van der Waals forces, hydrogen bonds, etc. A higher melting point indicates that the molecules are closely bound and the structure is stable. The boiling point is related to the temperature at which the liquid state changes to a gas state, reflecting the volatility of the compound. These two are of great significance to the thermal stability of the compound and the choice of processing conditions.
Thermal stability cannot be ignored either. Within a certain temperature range, the compound can maintain its own structure and properties stable, but if the temperature is too high, chemical bonds or fractures will cause structural changes. This property needs to be considered when applying in high temperature environments.
Spectral properties, it has a unique absorption peak in infrared spectroscopy, nuclear magnetic resonance spectroscopy, etc. Infrared spectroscopy can reveal the vibration information of chemical bonds in molecules, which helps to determine functional groups; nuclear magnetic resonance spectroscopy can provide information on the chemical environment of hydrogen atoms, carbon atoms in molecules. With these spectral properties, the structure of compounds can be accurately identified.

I haven't heard the exact price of "2,2 '-bis (2-chlorophenyl) -4,4', 5,5 '-tetraphenyl-1,1' -biimidazole" in the market. However, the price of this product and chemical substances often varies depending on various factors.
First, it is about purity. If it is high purity, the price must be expensive; if it is slightly lower purity, the price may be slightly cheaper. Second, the manufacturer is also the main factor. Different manufacturers have different processes and costs, resulting in different prices. Third, the purchase volume has a great impact. If the purchase volume is large, the merchant may give a discount, and the price may drop; if the purchase volume is small, the price may be high.
Furthermore, the state of market supply and demand also affects its price. If there are many applicants and few suppliers, the price will increase; if the supply exceeds the demand, the price may decrease. And the price varies from region to region. Prosperous places, or due to high transportation and operating costs, the price is slightly higher; remote places, or due to low costs, the price is slightly lower.
In my opinion, if you want to know the exact price, you can consult the store or website where the chemical reagent is sold, or negotiate with the supplier to get the current accurate price.
