A novel chitosan derivative carrying the benzene group was synthesized by Michael reaction. The chemical structures of the compounds were characterized by FT-IR, UV-vis spectrometry, XRD, elemental analysis, and 1H NMR spectroscopy in detail. The degree of substitution (DS) of chitosan derivative was calculated by elemental analysis. The UV-vis results indicated that the derivatives had ultraviolet absorption at 265 and 273 nm. XRD analysis showed that the derivatives were amorphous. The derivatives could dissolve in water. Taking advantage of the known capacity of solubility and ultraviolet absorption, the chitosan derivatives opened new possibilities for use as a sunscreen.
通过迈克尔加成反应合成了一种新型的带有苯基团的壳聚糖衍生物。通过傅里叶变换红外光谱（FT-IR）、紫外可见光谱（UV-vis 光谱）、X 射线衍射（XRD）、元素分析和 1H 核磁共振波谱（1H NMR 光谱）对化合物的化学结构进行了详细的表征。通过元素分析计算了壳聚糖衍生物的取代度（DS）。紫外可见结果表明，衍生物在 265nm 和 273nm 处有紫外吸收。XRD 分析表明，衍生物为无定形。衍生物可以溶解在水中。利用已知的溶解度和紫外吸收能力，壳聚糖衍生物为防晒剂的应用开辟了新的可能性。
