Problems solved by technology

It is known from physical optics that the increase of the refractive index of the material by the benzene ring is mainly due to its easy polarizability, but the increase in the refractive index of the material is limited, so other heteroatom groups must be introduced to obtain a resin with a higher refractive index
[0003] For example, introducing heavy atoms such as bromine and iodine into organic resin molecules can effectively increase the refractive index of the compound, but the disadvantage is that the organic resin is unstable to heat and light, and is prone to aging and discoloration after long-term use.
In addition, when it is used in electronic grade products, the residual halogen in its production process can easily corrode electronic components
[0004] In addition, another method for increasing the refractive index of materials is to add high-refractive-index inorganic oxide fine particles to organic resins, but this technology has the following disadvantages: the added and dispersed particles in the resin will stabilize the resin for long-term storage Therefore, it is necessary to balance the refractive index and stability of the system

Embodiment 1

[0028] Embodiment 1: Synthetic preparation of high refractive index resin

[0029]

[0030] In a four-neck flask equipped with mechanical stirring, heating, reflux condensation and constant pressure dropping funnel, add 46.5g (0.1mol) triphenylisocyanate and butyl acetate respectively, gradually heat up to 50 degrees, drop 11.6g (0.1mol) of hydroxyethyl acrylate, after the dropwise addition, the reaction was continued for 2 hours. Then a butyl acetate solution containing 18.8 g (0.2 mol) of phenol was added dropwise, and the progress of the reaction was monitored by thin-layer chromatography. When the composition of the reactant system is basically unchanged, the temperature is lowered to stop the reaction. After filtration, the solvent was removed under reduced pressure, and the product was obtained after purification with a yield of 83%.

Description

technical field [0001] The invention relates to the field of photoelectric display, in particular to an improved high-refractive index resin. Background technique [0002] In the field of optoelectronic materials, transparent resins are being commonly used in anti-reflection coatings for liquid crystal displays, transparent coatings for solar cells, light-emitting diodes, and CCD and CMOS sensors. Such optoelectronic materials generally require not only transparency but also a high refractive index for efficient light emission and light collection. It is known from physical optics that the increase of the refractive index of the material by the benzene ring is mainly due to its easy polarizability, but the increase in the refractive index of the material is limited, so other heteroatom groups must be introduced to obtain a resin with a higher refractive index . [0003] For example, introducing heavy atoms such as bromine and iodine into organic resin molecules can effecti...
