| titleOfInvention | Blue light absorption material, preparation method and application thereof, and blue light prevention lens |
| abstract | The invention provides a blue light absorption material, a preparation method and application thereof, and a blue light prevention lens, and relates to the technical field of organic light absorption materials. The invention provides a blue light absorption material, which has a structure shown in a formula I, in formula I, R comprises triphenylamino, 5- (diphenylamino) furyl, 5- (diphenylamino) thienyl, 5- (4-trifluoromethyl-phenyl) -thienyl or 5-methoxybenzothiazolyl. The blue light absorption material provided by the invention has an electron-withdrawing group-supplying diester-based structure, and can promote intramolecular charge transfer to realize light absorption; the electron-withdrawing ability of the ester group is weak, the introduction of the ester group is beneficial to adjusting the charge transfer in molecules, and further the high-energy short-wave blue light absorbing effect is good; moreover, the blue light absorbing material can be directly doped into the lens base material without influencing the thickness of the lens, the blue light transmittance and blue light blocking ratio of the blue light preventing lens containing the blue light absorbing material are high, and the blue light preventing effect is good. |
