Description
Technical field
The invention belongs to liquid crystal material technical fields, are related to a kind of polymerizability compound and its system containing indane structural
Preparation Method and application.
Background technique
In recent years, liquid crystal display device is widely used in various electronic equipments, such as smart phone, tablet computer, automobile
Navigator, television set etc..Representative liquid crystal display mode has twisted-nematic (TN) type, super twisted nematic (STN) type, face inscribe
Change (IPS) type, fringing field switching (FFS) type and vertical orientation (VA) type.Wherein, when VA mode is due to having quickly decline
Between, the image of high contrast, wide viewing angle and high quality, and receive more and more attention.
However, liquid crystal media used in the display element of the active array addressing mode of VA mode etc., there is not for itself
Foot, if image retention level will be significantly worse than the display element of positive dielectric anisotropy, the response time is slow, and driving voltage is relatively high
Deng.To solve the above-mentioned problems, there are some novel VA display technologies, such as MVA technology, PVA technology, PSVA technology.Its
In, PSVA technology had both realized the similar wide view angle display pattern of MVA/PVA, also simplified CF technique, and realizing reduces CF
While cost, aperture opening ratio is improved, higher brightness can also be obtained, and then obtain higher contrast.Further, since whole
The liquid crystal in face has pre-tilt angle, does not have domino delay phenomenon, can also obtain under the driving voltage maintained like faster
Response time, image retention level will not be affected.
The prior art has been found that the application aspect of LC mixture and RMs in PSA display still has the shortcomings that.It is first
It first, is not up to the present that each desired solvable RM is suitable for PSA display: simultaneously, if it is desired to by means of UV
Light is polymerize (this may be advantageous for certain applications) without adding photoinitiator, then selection becomes smaller: in addition,
LC mixture (hereinafter also referred to as " LC body mixture ") combines " material system " to be formed with selected polymerizable components and answers
With minimum rotary viscosity and best photoelectric properties, for increasing " voltage retention " (VHR) to reach effect.In PSVA
Aspect is very important using the high VHR after the irradiation of (UV) light, otherwise will lead to final display and the problems such as image retention occur.
Up to the present, due to there is no inclination angle to occur or occur deficiency after polymerizable unit is too short for UV sensibility wavelength or illumination
The poor problem of homogeneity after illumination of inclination angle or polymerizable components.Not all LC mixture with polymerizable group
The combination being grouped as is adapted to PSVA display.
Therefore, the synthesis and structure-performance relation of the new structural polymerizable compound with excellent properties are ground
Study carefully an important process as field of liquid crystals.
Summary of the invention
The first object of the present invention is to provide a kind of polymerizability compound for polymer stabilizing technology.Contain the change
The liquid-crystal composition orientation effect for closing object is more preferable, and polymerization is more complete, and residual is lower, and the compound is cheap, performance is stablized,
It can be widely used for field of liquid crystal display, there is important application value.
