The invention relates to a non-conjugate dye with benzophenone p-nitro stilbene and the preparation and application, in particular to the preparation of non-conjugate dye with benzophenone p-nitro stilbene and the application in polymerization, belonging to the field of organic dye, the typical chemical formula of which is the right formula; wherein, in the molecular structural formula (I) the n represents 0 to 6, and R represents hydrogen, methyl, ethyl, propyl, butyl, pentyl, hexyl, or is completely the same with the substituent in the forth degree. The non-conjugate dye with benzophenone p-nitro stilbene is prepared by ether bond via 4-benzophenone diethyl phosphonate and the derivative of p-nitro stilbene compound with hydroxyl reacting in a glass vessel and in alkaline condition, the maximum absorption of which is in visible light region, and can be used as photoinitiator forming a photosensitive system together with promoter triethanolamine to be the visible photopolymerization of vinyl monomer in solut
