新型农膜用均三嗪系列蓝光转光剂的合成及其表征

目的]确定了新型农膜用均三嗪系列蓝光转光剂的合成工艺,并分析了其光谱特征。方法]用简单常规溶剂乙腈、乙醇和苯等合成了3种化合物,并通过红外光谱和核磁氢谱确定了3种化合物的组成结构,用紫外和荧光光谱探讨了这类化合物的光谱特征。结果]在波长310～385nm的紫外光激发下,此系列化合物在波长410～480nm较宽的范围内发出强蓝光,有望成为一类新型的蓝光光转换剂添加到聚乙烯农膜中,应用到农业,从而提高植物光合作用效率,达到农作物增产增收的目的。结论]该研究可为新型农膜的开发奠定基础。

Synthesis and Characterization of Novel Blue Light-conversion Agent of Triazine series in Agricultural Film

Objective] The aim was to determine the synthesis technique of novel blue light-conversion agent of triazine series in agricultural film and analyze its spectral features.Method] The three compounds TPT、MDBS、DPBS was synthesized with acetonitrile,ethanol,cinnaldehyde,etc.and their constituents were characterized by IR and 1H NMR.The spectral signature of the serial compounds was analyzed by UV and fluorescence spectrum.Result] The compounds exhibited a stronger blue light by a UV excited wavelength with 310-385 nm and its peak was at 410-480 nm.It would become a new kind of blue light-conversion agent to improve plant Photosynthetic efficiency and increase crop yield in agricultural film.Conclusion] The study laid a foundation for developing new agricultural film.
