Description
Technical Field
The invention relates to a polymerizable compound based on 2, 7-dihydroxyfluorene, a preparation method and application thereof, in particular to application of the polymerizable compound in various optical anisotropic bodies; belongs to the technical field of optical materials.
Background
Polymerizable (mesogenic) compounds (RM) are gaining increasing attention as starting materials for the preparation of various optically anisotropic bodies. The prior art generally applies a solution of a polymerizable compound onto a substrate, aligns it, and cures it by heating or irradiating an active energy ray, thereby forming an optically anisotropic polymer film, also called an optically anisotropic body, having uniform orientation. The film orientation may be planar (liquid crystal molecules oriented substantially parallel to the layer), homeotropic (rectangular or perpendicular to the layer) or tilted, as well as cholesteric.
The optically anisotropic body includes, but is not limited to, an optical retardation film (phase difference film), an optical compensation film, a vision expanding film, a reflective film, a selective reflective film, an antireflection film, a brightness enhancement film, a liquid crystal alignment film, a polarizing element, a circular polarizing element, an elliptical polarizing element, and other various optical elements according to the application field.
Polymerizable compounds, while stable at room temperature, degrade at elevated temperatures. For example, when heated for a period of time, the optical properties of the dispersion or retardation degrade, resulting in a degradation of the properties of the optically anisotropic body over time. According to different studies, this can be attributed to a low degree of polymerization, a correspondingly high residual radical content of the polymer, shrinkage or thermo-oxidative degradation of the polymer, etc.
The optically anisotropic body is required to have various properties such as optical properties, polymerization rate, solubility, melting point or glass transition temperature, transparency, mechanical strength, surface hardness, heat resistance and light resistance, which are required. The characteristics of the optically anisotropic body depend not only on the kind of the polymerizable compound used but also on the ratio of the polymerizable compounds.
RM optical retardation films with low diacrylate content are well suited for applications where good adhesion of the RM optical retardation film to the substrate is important. However, in RM optical retardation films with low diacrylate content, the optical retardation usually drops significantly, especially due to polymer shrinkage.
On the other hand, in the case of the optical retardation film, it is necessary to add a polymerizable compound to a mother liquid crystal to obtain a polymerizable composition, thereby making the wavelength dispersion of birefringence thereof small while effectively improving the viewing angle of the display. In this case, a high addition concentration of the polymerizable compound is advantageous. However, the conventional polymerizable compound is not easily stored stably in such a case and is easily precipitated. In the case where the maximum stable concentration is insufficient, there is brought about an adverse effect that the nonuniformity of the film becomes poor.
Therefore, it is required to develop a polymerizable compound, the use of which can solve the above-mentioned technical problems.

Further, the compound can exhibit not only favorable substrate adhesion in RM optical retardation films, but also good high temperature stability. Meanwhile, high addition concentration in the mother liquid crystal can be realized, sufficient maximum stable concentration is obtained, and further, the nonuniformity of the film is improved.

to evaluate the storage stability, the stable storage concentration of the evaluation compound was measured. The storage stability concentration is defined as: the compound to be evaluated was added in an amount of 5% to 50% in increments to the mother liquid crystal, and the prepared composition was left at 10 ℃ for 10 weeks to have a maximum concentration of the compound at which crystal precipitation did not occur. The maximum added concentration of the compound means that the storage concentration is high and the compound does not crystallize even when stored for a long time.

The alignment film was coated with a polyimide solution for an alignment film and a glass substrate having a thickness of 0.7mm by a spin coating method, dried at 100 ℃ for ten minutes, and then fired at 200 ℃ for 60 minutes to obtain a coating film, and the obtained coating film was subjected to a rubbing treatment using a commercially available rubbing apparatus.
In order to reduce the birefringence and improve the viewing angle, a polymerizable composition was prepared by adding 35% of a compound to be evaluated to a mother liquid crystal M, and a photopolymerization initiator Irgacure 907 (manufactured by BASF Co., Ltd.), 1%, 0.1% of 4-methoxyphenol and 80% of chloroform were added to prepare a coating solution. The coating liquid was applied by spin coatingWith the rubbed glass substrate. After drying at 80 ℃ for 1 minute, further drying at 120 ℃ for 1 minute, and then using a high pressure mercury lamp at 40mW/cm2The film to be evaluated was prepared by irradiating ultraviolet light at the intensity of (1) for 25 seconds.
The degree of unevenness of the obtained polymer was evaluated by observation with a polarization microscope. The number of films to which the compound to be evaluated was added was counted in a non-uniform manner, 10 films each were prepared. The number of unevenness observed in 10 sheets of films was counted up, and the number of unevenness was found to be excellent when the number of unevenness was 0, good when the number of unevenness was 1, medium when the number of unevenness was 1 to 10, and poor when the number of unevenness was ten or more.
