This is a complex chemical substance. If you want to understand its physical properties, please listen to me in detail.
The form of this substance, under room temperature and pressure, or a solid state. Looking at the complexity of its molecular structure, the close interaction between atoms makes it have a relatively stable solid state structure. Its color, or white, light yellow, etc., due to the influence of intra-molecular electron transition characteristics and conjugate systems, it appears in the visible light band.
As for the melting point, due to the strong intermolecular forces, high energy is required to destroy the lattice structure, so the melting point may be quite high, or above hundreds of degrees Celsius. The same is true for the boiling point. To convert it from a liquid state to a gaseous state, a large amount of energy is required to overcome the attractive force between molecules, and the boiling point may be very high.
In terms of solubility, because the substance has both polar groups and non-polar aromatic ring structures in the molecule, the solubility may be limited in polar solvents such as water, due to the large difference in polarity. For non-polar or weakly polar organic solvents, such as toluene and dichloromethane, the solubility may be relatively good, because the molecules can interact through van der Waals forces.
The density may be slightly higher than that of common organic compounds, due to its complex molecular structure, large number of atoms, and large mass per unit volume.
Furthermore, its conductivity is extremely weak, and it can almost be regarded as an insulator. Because there are no free-moving electrons or ions in the molecule, it is difficult to conduct current.
The physical properties of this substance are determined by its unique molecular structure, and its applications in chemistry, materials and other fields are also closely related to its physical properties.

To prepare 2,2 '-bipyridine-4,4' -dicarboxylic acid, 4,4 '-bis (4-phenyl-2H-1,2,3-triazole-2-yl) -dicarboxylic salt, there are various methods.
First, bipyridine is used as the starting material, and the carboxyl group is introduced in the appropriate position first. The electrophilic substitution reaction can be used to make bipyridine and carboxyl-containing reagents, such as halogenated carboxylic acid derivatives, act under suitable catalyst and reaction conditions to form 2,2' -bipyridine-4,4 '-dicarboxylic acid. Subsequently, the dicarboxylic acid is reacted with a copper reagent containing 4-phenyl-2H-1,2,3-triazole-2-yl, such as a specific copper salt with a corresponding triazole-containing ligand prepared in advance. Under conditions such as suitable solvents and temperatures, the target 4,4 '-bis (4-phenyl-2H-1,2,3-triazole-2-yl) -dicuprate is generated through a coordination reaction.
Second, a fragment containing 4-phenyl-2H-1,2,3-triazole-2-yl can also be constructed first. Through click chemistry and other reactions, the azide-containing phenyl derivative and the alkynyl-containing 1,2,3-triazole derivative undergo cycloaddition reaction under copper catalysis to form a triazole-containing intermediate. After that, the intermediate is connected to the bipyridine derivative and introduced into the carboxyl group, which is converted into the target product through a series of reactions. During the reaction process, the reaction conditions, such as temperature, pH, and the ratio of reactants, need to be carefully adjusted to ensure the smooth progress of each step of the reaction and improve the yield and purity of the product. The choice of solvent is also crucial. Appropriate organic solvents or mixed solvents should be selected according to the reaction characteristics of each step to promote the dissolution of the reactants and the reaction process. At the same time, the type and amount of catalysts involved in the reaction have a significant impact on the reaction rate and selectivity, and need to be determined by experimental optimization. In this way, after carefully designing and manipulating the reaction in multiple steps, the required 2,2 '-bipyridine-4,4' -dicarboxylic acid, 4,4 '-bis (4-phenyl-2H-1,2,3-triazole-2-yl) -dicuprate salt can be obtained.

First, this substance is chemically active, or reacts with other substances. When operating, it must keep the environment clean, away from fire and heat sources. The utensils used should be dry and clean to prevent unexpected reactions caused by impurities.
Second, there is a risk of human contact. If it accidentally touches the skin, it should be rinsed with plenty of water as soon as possible; if it enters the eyes, it should be rinsed with flowing water or normal saline immediately, and seek medical attention in time. Protective clothing, protective gloves and goggles should be worn during operation for comprehensive protection.
Third, its odor and volatile gases or irritate the respiratory tract. The place of use must be well ventilated, and if necessary, equipped with ventilation equipment. If you feel uncomfortable breathing during operation, you should quickly leave the scene and go to a place with fresh air.
