Abstract

The invention discloses a quinophthalone compound shown in the formula A, a preparation method thereof and application of the quinophthalone compound as a light absorption material. The preparation method comprises the steps that phthalic anhydride and 2-methyl-3-hydroxyquinoline are added into a reaction container according to the weight ratio of 1:(3-5), a solvent is 1,3,5-trichlorobenzene, thetemperature is slowly increased to 150-200 DEG C, and the temperature is kept constant for 2-3 h for performing a condensation reaction. According to application, the quinophthalone compound shown inthe formula A, nanometer titania of the core-shell structure and an ultraviolet light absorber are dispersed into optical resin to form an anti-blue-light resin material. The material has the performance for distinguishing and absorbing blue light of different wave bands, the low transmittance is kept for the short and medium wave band harmful blue light, the high transmittance is kept for long wave band beneficial blue light and visible light of other wave bands, the eyesight is protected, and the problem that damage is caused by ultraviolet light and blue light to the human eyes is well solved.

Description

technical field [0001] The invention belongs to the technical field of light absorbers, and in particular relates to a light absorber with specific absorption wavelength in the 220-470nm spectral region and a preparation method thereof. Background technique [0002] We all know that ultraviolet rays can damage people's eyes, but many people don't know that blue light in visible light can also cause damage to eyes. As part of visible light, blue light has extremely high energy, and its wavelength range is between 400 and 500nm. With the widespread popularization of electronic products such as computers, mobile phones, and ipads, unnatural light with blue light as the main body will cause irreversible damage to human eyes. Damage, causing dry eyes, fatigue, tearing, accelerated myopia, macular area disease and other problems. According to the orange warning issued by the World Health Organization (WHO) at the end of 2009: the potential invisible threat of blue light to humans...
