In this way, light modulation can be effectively realized when the liquid crystal display is operating.
Furthermore, its chemical stability is quite good, which can resist the erosion of chemical substances in the environment and prolong the service life of the liquid crystal display. And because it contains fluorine atoms, it improves the polarity and solubility of liquid crystal molecules, optimizes the electro-optical properties of liquid crystal, and makes the display have a wider color gamut, better contrast and faster response speed. It is widely used in the manufacture of many display technologies, such as liquid crystal display (LCD), and contributes a lot to improving display quality.
What are the physical properties of 4- [ (Trans, Trans) -4 '-Pentyl [1,1' -Bicyclohexyl] -4-Yl] -1,2-Dipfluorobenzene
4 - [ (anti, anti) -4 '-pentyl [1,1' -dicyclohexyl] -4-yl] -1,2-difluorobenzene, the physical properties of this substance are quite unique. Its appearance is often clear and transparent, like a mountain spring, pure and free of impurities.
In terms of phase state, within a specific temperature range, it exhibits the state of liquid crystal. Just like a spirit that can adapt to changes in the outside world and switch flexibly, this liquid crystal state gives it unique application potential in the display field. Its melting point is in a certain range of values, like a threshold, beyond this temperature limit, the phase state of matter will change. The boiling point is also a specific value, which reflects the conditions under which the substance converts to a gaseous state when heated.
In terms of solubility, it exhibits certain solubility properties in common organic solvents. Just like salts incorporated into water, it can be dissolved in solvents such as aromatics and halogenated hydrocarbons, and this solubility facilitates its operation in chemical synthesis and material preparation.
Density is also one of its important physical properties, with exact values. This value is related to the behavior of the substance when mixed with other substances or participating in a specific process.
The refractive index also has a specific value. When light shines on the substance, it will produce a refractive phenomenon according to this refractive index, just like light changing its path when traveling through different media. This property is of great significance in optical related applications.
What is the chemical synthesis method of 4- [ (Trans, Trans) -4 '-Pentyl [1,1' -Bicyclohexyl] -4-Yl] -1,2-Dipfluorobenzene
To prepare 4- [ (trans, trans) -4 '-pentyl [1,1' -dicyclohexyl] -4-yl] -1,2-difluorobenzene, the following method can be followed.
First take the appropriate dicyclohexyl derivative, which when the amyl group is substituted at the 4 'position and has the reverse, reverse configuration. The dicyclohexyl structure can be constructed by a multi-step reaction starting from cyclohexanone. Cyclohexanone is first reacted with a suitable halogenated hydrocarbon under the action of a suitable base and catalyst to introduce the alkyl chain. After that, through reduction, cyclization and other steps, the dicyclohexyl moiety is constructed, and the inverse and inverse configuration of the 4 'amyl group is ensured.
For the 1,2-difluorobenzene moiety, benzene can be started from benzene. Benzene is first halogenated, and a halogen atom is introduced into the benzene ring with a specific halogenating agent and reaction conditions. Subsequently, the halogen atom is replaced with a fluorine atom in a suitable fluorine source, such as potassium fluoride, in a suitable solvent and catalyst system to obtain 1,2-difluorobenzene.
Finally, the amyl-containing dicyclohexyl derivative is connected to 1,2-difluorobenzene through a suitable coupling reaction. Such as the coupling reaction catalyzed by transition metals, such as the reaction catalyzed by palladium. In the presence of appropriate bases, ligands and solvents, the two are coupled to obtain 4- [ (trans, trans) -4 '-pentyl [1,1' -dicyclohexyl] -4 '-yl] -1,2' difluorobenzene. The whole process requires fine control of reaction conditions, including temperature, reaction time, proportion of reactants, etc., to obtain a product with higher yield and purity.
