The invention discloses a dioxybenzone containing anitro-azobenzene dye by an ether bond and a synthesizing method and application thereof, pertaining to the organic dye field, and particularly relates to an anitro-azobenzene dye that is connected with the dioxybenzone by the ether bond and application thereof in light polymerization. A typical chemical structure general formula of the compound of the anitro-azobenzene dye is showed on the right, wherein, n in the molecular structural formula (I) represents 1-6, R represents methyl, ethyl, propyl, butyl, amyl, hexyl or is completely the same as a substituting group at the other side of N. 4-bromomethyl dioxybenzone reacts with derivative of anitro-azobenzene compound that contains hydroxyl under alkaline conditions in a glass container, and the dioxybenzone containing anitro-azobenzene dye is prepared by the ether bond. The maximum absorption of the anitro-azobenzene dye is at a visible light area; therefore, the invention can be used as photoinitiator and th
