1312006 V. INSTRUCTIONS (1 (Please read the note on the back and then fill out this page) The present invention relates to a palm compound, a liquid crystal mixture containing the palm compound, a polymer obtained from a palm compound and a liquid crystal mixture. And the present invention is also directed to a palm compound, a liquid crystal mixture, and the resulting polymer in a liquid crystal display, active and passive optical components such as polarizers, compensators, alignment layers, color filters, or laser imaging elements, Adhesives, synthetic resins with anisotropic mechanical properties, cosmetic and pharmaceutical compositions' diagnostics, liquid crystal pigments, decorative and security applications, nonlinear optics, optical message storage or as a palm-like dopant Uses The palm compound can be used as a dopant to promote or enhance the helical winding of the liquid crystal mixture used in liquid crystal displays. According to equation (1), the pitch P of the molecular helix for most practical applications ( Taking the first approximation 値), which is inversely proportional to the concentration c of the palmitic dopant in the liquid crystal master mixture: the scale factor is for the palm dopant Spiral winding ability (Η TP ). Printed by the Ministry of Economic Affairs, Intellectual Property Bureau, 8 Workers' Consumption Cooperatives For many applications, it is better to have the LC mixture have a entangled phase. Among these applications are phase change displays and exploration hosts (guest Host ) Display, active and passive matrix TN and S TN displays such as AMD - TN, ferroelectric displays, cholesteric displays such as SSCT (Interface stabilized cholesteric structures) or PSCT (polymer stabilized cholesteric structures) The display also includes a display having temperature compensation characteristics by appropriately selecting a single cholesteric compound such as the present invention or in combination with another pair of palmitic dopants. For these applications, It is advantageous to apply the paper scale to the Chinese National Standard (CN'S) A4 specification (2I0X297 mm) -4 - 1312006 - ΒΤ 5. Inventive Note (Use a high HT P pair of palm dopants in order to make this necessary induction The amount of dopant required for the required pitch is reduced. (Please read the notes on the back and fill out this page.) For many applications, the preferred one is to make the LC mixture Strong spiral winding, thereby shortening the pitch length. For example, in liquid crystal mixtures that can be used in selective reflection cholesteric displays such as SSCT or PSCT, the pitch must be chosen to make the cholesteric spiral The wavelength of reflection is at most 可见光 in the visible range. Another possible application is a polymer film with a palm-like liquid crystal phase for optical components, such as a cholesteric broadband polarizer or a retardation film. From equation (1) It can be seen that a short pitch can be achieved by using a high amount of dopant or a dopant having a high HT P. For example, the palm compound is disclosed in International Patent Application No. 95/16007, Case No. 98/00428 and British Patent No. 2 328 207. Printed by the Ministry of Economic Affairs, the Intellectual Property Office, and the Consumer Cooperatives. However, the prior art's palm-like dopants often exhibit lower HTP 値, so a large amount of dopants must be used. This is a disadvantage because the palm dopant can only be used as a pure enantiomer, so it is expensive and difficult to synthesize. Furthermore, when using prior art palm-type dopants in high amounts, they often negatively affect the characteristics of the liquid crystal master mixture, such as the enthalpy point, dielectric anisotropy Δ ε, viscosity, driving voltage, or Conversion time. Another disadvantage of prior art techniques for palm dopants is that they often exhibit low solubility in the liquid crystal master mix resulting in undesirable crystallization at low temperatures. In order to overcome this shortcoming, it is necessary to apply two or more paper scales to the Chinese National Standard (CNS) Α 4 specifications _ (210X297 mm) -5- 1312006 A7 B7 V. Invention Description (i different pairs of palms) The dopant is added to the main mixture. This means a high cost' while also requiring additional effort to compensate the temperature of the mixture, just as it is necessary to select different dopants so that their temperature coefficients compensate each other when entangled. Therefore, it is easy to synthesize and can be used in a low amount, showing an improved temperature stability of the cholesteric pitch, and can also utilize a constant reflection wavelength without affecting the characteristics of the liquid crystal main mixture, and in the main mixture. High Η TP exhibiting good solubility has considerable demand for palm compounds. It is an object of the present invention to provide a palm compound having these characteristics, but without the disadvantages of the prior art as described above for palm powder dopants. Another object of the present invention is to extend the scope of the business of the palm compound which can be used exclusively as a dopant. It has been found that these objects can be provided by On the palm compound reached. Therefore, one object of the present invention as follows based on the palm of the compounds of formula I (Read Notes on the back and then fill the page)

The photoisomerization of the photoisomerizable compound of formula I by UV light of 360 nm can promote the isomerization of the double bond of the photoisomerizable group from E to Z, thus completely changing the morphology of the molecule, thereby Physical molecular properties are more entangled. The palm compound of Formula I can be mixed with other meso-forming compounds to obtain a palmitic liquid crystal mixture. It is assumed that the liquid crystal mixture, such as a cholesteric mixture, is applied to a surface in a thin layer and aligned, and then photolyzed by UV light of 1600 nm, which will change the isomerizable dopant. The form reduces the ΗTP in sequence, so it has a comprehensive effect on increasing the pitch and the reflection wavelength of the mixture. If the irradiation is carried out through the reticle to the liquid crystal mixture coating doped with the compound which is isomerizable to the palm light, a pattern having a reticle shape can be obtained, in which the coatings of different regions will appear different.

Straightening and curing are carried out in the liquid crystal phase of the mixture. Actinic radiation means the use of light, such as u V, IR or visible light, to irradiate with X-rays or r-rays, or to use high-energy particles. For example, ion or electron irradiation. For example, the source of actinic radiation is a single uv lamp or a group of UV lamps. Another possible source of actinic radiation is a laser such as a uv laser, an IR laser or a visible laser. For example, when the polymerization is via UV light, a photoinitiator which decomposes under UV irradiation may be used to generate radicals or ions which initiate the polymerization reaction. It is also possible to use a cationic photoinitiator. When the reactive melo group is matured by a vinyl group and an epoxide reaction group, the photo-curing can be carried out by using a cation instead of a radical.
