Embodiment 1

[0042] Embodiment 1 synthetic formula (I-1) compound, 1-phenyl-3-(4-butyl styryl)-5-(4-tert-butylphenyl) pyrazoline

[0043]

[0044] 16.2 g of 4-tert-butylbenzaldehyde and 3.0 g of acetone were added to the freshly prepared sodium methoxide solution and stirred at room temperature for 3 hours. After washing with water and drying, the product bis(2-(4-tert-butyl)phenylvinyl)ketone was obtained. Take 7g of bis(2-(4-tert-butyl)phenylvinyl)ketone and 2.2g of phenylhydrazine and react in acetic acid for 4 hours. After cooling, the product was purified to obtain 1-phenyl-3-(4-butylstyryl)-5-(4-tert-butylphenyl)pyrazoline with a melting point of 192-197°C. UV-VIS (ETOH.max.) 387 nm.

Embodiment 2

[0045] Example 2 Synthesis of (I-2) compound, 1-phenyl-3-(p-methoxystyryl)-5-(p-methoxyphenyl) pyrazoline

[0046]

[0047] With embodiment 1 method, but replace 4-tert-butylbenzaldehyde with p-methoxybenzaldehyde, obtain 1-phenyl-3-(p-methoxystyryl)-5-(p-methoxyphenyl ) pyrazoline (I-2) compound with a melting point of 159°C. UV-VIS (ETOH.max.) 381 nm.

Embodiment 3

[0048] Embodiment 3 synthetic formula (I-3) compound, phenyl-3-(p-methoxystyryl)-5-(p-dimethylaminophenyl) pyrazoline

[0049]

[0050] With embodiment 1 method, but replace 4-tert-butylbenzaldehyde with p-dimethylaminobenzaldehyde, obtain phenyl-3-(p-methoxystyryl)-5-(p-dimethylaminobenzaldehyde Phenyl) pyrazoline, melting point 192°C, UV-VIS (ETOH.max.) 419 nm.

Abstract

The invention relates to an anti-blue-ray system. The anti-blue-ray system is characterized in that an anti-blue-ray agent in the system has a pyrazoline compound structure as shown in a formula (I) which is described in the specification or/and a cinnamic acid compound structure as shown in a formula (II) which is described in the specification. The compound as shown in the formula (I) or/and thecompound as shown in the formula (II) can fully absorb short-wavelength blue light to protect the eye, and can also selectively absorb long-wavelength blue light so as to allow transmitted light to present particularly good visual perception. The anti-blue-ray system of the invention is applicable to products such as optical films, optical lenses, goggles, skin care products, lighting products, paints, adhesives and panels. The products have light-colored appearance and transmitted light presents particularly good visual perception.
