Paragraph 0017, (2017/08/28)
The invention discloses a phosphono-replaced methyl alcohol derivative, and a preparation method and application thereof. The phosphono-replaced methyl alcohol derivative has the advantages that a (hetero) aryl methyl alcohol derivate serves as an initiator, and raw materials are easy to get and have great varieties; products obtained according to the preparation method have various types and wide application ranges, and serve as ligands which coordinate with rhodium to obtain various aldehydes through catalyzed synthesis; the phosphono-replaced (hetero) aryl methyl alcohol can be transformed into phosphonic compounds conveniently; the phosphonic compounds serving as photoinitiators can be widely applied to production of high polymer materials, paint, binders, adhesive tapes and the like. The preparation method has the advantages that reactions are achieved in the air, reaction conditions are mild, yield of target products is high, pollution is small, reaction operations and post-treatment processes are simple, and the preparation method is suitable for industrial production.

The invention discloses an organic phosphorus compound as shown in the figure and a preparation method thereof. The organic phosphorus compound has an acyl phosphine active functional group structure and can be used as an UV-light initiator. More important is that the compound aromatic ring is coupled with a tertiary amine structure, the ultraviolet absorption wavelength is moved to 380nm-395nm and the unsaturated monomer polymerization can be effectively triggered under the radiation of UV-LED lamp. Besides, the solubility of the compound in various resins and low polymer is excellent. The organic phosphorus compound is a novel acyl phosphine photoinitiator.

The two-step method for the synthesis of acyl-phosphine oxides from aromatic aldehydes was optimized giving the products in 52-97% overall yield. Linear and nonlinear optical properties of series of acyl-phosphine oxides possessing substituents with different electron-donating ability were investigated. Two-photon absorption cross sections (σ2) of push-pull acyl-phosphine oxide was determined as 9GM via z-scan measurements with femtosecond laser pulses. Using acyl-phosphine oxides possessing dipolar structure as initiators, 3D nanopatterns were successfully fabricated by two-photon initiated polymerization. These compounds also initiate classical photopolymerization when excited with UV radiation.
