摘　　要：以γ-氯丙基三甲氧基硅烷与对二甲胺基肉桂酸为原料,通过酯化反应合成了对二甲胺基肉桂酰氧基丙基三甲氧基硅烷,利用IR、^1H NMR、^13C NMR对其结构进行了表征,并对其紫外吸收性能进行了研究,紫外吸收区域为305~400 nm,最大吸收波长λmax为361.6 nm,最大摩尔吸光系数εmax为1.94×10^4.研究结果表明,该化合物是一种较好的新型的反应性UVA紫外线吸收剂.玻璃涂层试验表明,对于5 mm普通硅酸盐玻璃,当涂层中γ-(对二甲胺基肉桂酰氧基)丙基三甲氧基硅烷的含量达到0.8 g/m^2时,涂层玻璃的紫外线平均透光率仅有0.01。P-dimethylamine cinnamoxypropyl trimethoxysilane were synthesized by esterification of γ-chloropropyl trimethoxysilane with p-dimethylamino cinnamic acid. Their structures were characterized by IR,^1H NMR and ^13C NMR. The ultraviolet absorption properties were investigated. The uv absorption area is 305-400 nm,maximum absorption wavelength is 361.6 nm or maximum molar absorption coefficient is 1.94×10^4. The results show that the compound is a new reactive UVA ultraviolet absorbent. The experiment of glass coating shows that for 5 mm ordinary silicate glass,when the content of γ-(p-dimethylamino cinnamoxy)propyltrimethoxysilane reaches 0.8 g/m^2,the average ultraviolet transmittance of coated glass was only 0.01.
