Title:
PREPARATION METHOD FOR SYNTHESIZING PHOTOSENSITIVE COMPOUND THROUGH CLAISEN-SCHMIDT REACTION
Document Type and Number:
WIPO Patent Application WO/2019/218418
Kind Code:
A1
Abstract:
Provided in the invention is a preparation method for synthesizing a photosensitive compound through a Claisen-Schmidt reaction. An aldehyde free of alpha-H and a ketone containing alpha-H are selected to be synthesized to obtain the product alpha, beta-unsaturated carbonyl compound. The preparation method is simple in condition and mild in reaction. The prepared photosensitive compound serving as a hydrogen abstraction type photoinitiator has a characteristic with a long wave length and small consumption, and has a good initiation effect on monomer PEGDA without adding initiation auxiliaries. Under an ultraviolet lamp, the absorption wavelength is subjected to red shift from 450 to 500 and finally subjected to blue shift to 400 or below. The photosensitive compound has an AIE effect.
