Through rational design and combination of other liquid crystal motifs, key parameters such as phase transition temperature and dielectric anisotropy of liquid crystal materials can be adjusted to meet the special requirements of different display modes (such as TN, IPS, VA, etc.) for liquid crystal materials, providing a material basis for the preparation of high-performance liquid crystal displays.

4- (4- [2- (4-ethylcyclohexyl) ethyl] cyclohexyl) -1,2-difluorobenzene, its physical properties are quite important.
First of all, its physical state is often liquid at room temperature. This is due to the interaction between molecules and structural characteristics. The alkyl part of the molecule, such as ethyl and cyclohexyl, gives the molecule a certain degree of flexibility, while the introduction of fluorine atoms, although enhancing the interaction between molecules, does not cause it to be in a solid state.
Second, its melting point is relatively low due to the complex molecular structure and diverse interactions between atoms, between about - 20 ° C and - 10 ° C. This is because the molecules are difficult to arrange in a regular manner to form a stable lattice, requiring a lower temperature to order.
As for the boiling point, due to the large molecular weight and the enhancement of intermolecular forces by fluorine atoms, the boiling point is higher, about 250 ° C to 270 ° C. Fluorine atoms have large electronegativity, which can generate strong van der Waals forces, which requires more energy for gasification.
In terms of solubility, it has a certain lipid solubility and can be soluble in most organic solvents, such as toluene, dichloromethane, etc. The alkyl group and aromatic ring part of its molecule are lipophilic groups, which can form a similar miscibility with organic solvent molecules. However, the solubility in water is extremely poor, because the overall non-polarity of the molecule is strong, and it is difficult to form effective interactions with water molecules. The density of
is slightly higher than that of water, about 1.1-1.2 g/cm ³. This is due to the large relative mass of fluorine atoms and the small atomic radius, resulting in a compact molecular structure and an increase in mass per unit volume. The refractive index of
is also an important property, about 1.50-1.52, reflecting its influence on the direction of light propagation, which is related to the structure of molecular electron clouds and the properties of chemical bonds.

To prepare 4- (4- [2- (4-ethylcyclohexyl) ethyl] cyclohexyl) -1,2-difluorobenzene, there are many ways to synthesize it. First, through halogenation, a suitable halogenating agent, such as hydrogen halide or halogen elemental substance, can be selected to halogenate the specific position on the benzene ring or cyclohexyl group of the raw material, and a halogen atom can be introduced, which is the basis for the subsequent reaction.
Following the method of nucleophilic substitution, the nucleophilic reagent is selected and reacted with the halogenated product, and a specific group can be connected to construct the carbon chain structure of the target molecule. During this time, the control of halogenation reaction conditions is quite important, and temperature, solvent, catalyst, etc. all affect the yield and selectivity of the reaction.
can also use reduction reactions to convert unsaturated bonds, such as carbon-carbon double bonds or triple bonds, into saturated bonds through the action of reducing agents, so that the molecular structure is more stable and meets the requirements of the target product. The reducing agents used are metal hydrides, such as lithium aluminum hydride, sodium borohydride, etc., each has its own application scenarios.
And organic metal reagents are also useful in synthesis, such as Grignard reagents or organolithium reagents, which can react with halogenated hydrocarbons or carbonyl compounds to form new carbon-carbon bonds, achieving the purpose of increasing carbon chains and building complex structures. However, such reagents have high activity, and the operation needs to be in an anhydrous and oxygen-free environment to prevent side reactions.
Furthermore, the functional groups in the molecule can be modified and converted through esterification, hydrolysis, etc., so that the final product conforms to the structure of 4- (4- [2- (4-ethylcyclohexyl) ethyl] cyclohexyl) -1,2-difluorobenzene. After each step of the reaction, the product can be separated and purified without any oversight, and high-purity products can be obtained by distillation, recrystallization, column chromatography, etc.
