邻香草醛是一种常见的有机合成中间体,是医学中常用的化学试剂。分子识别是指在复杂的混合液体中能够依靠形状、大小、化学功能等特性与可统一分子互补的主体分子进行区分与结合。作为常用的化学试剂,对邻香草醛进行区分是日常工作中不可避免的问题。邻香草醛的分子印记聚合物是实现这一区分的主要途径。本文探讨利用紫外光引发原位聚合的方法制备了具有支撑膜的邻香草醛分子印记聚合物膜。用傅立叶红外光谱等仪器测定分子印记聚合物膜的结构和表面构造。通过相关实验,分子印记聚合膜在干扰物的影响下依然能够显现良好的选择性透过性能。 Ortho vanillin is a common organic synthesis intermediates, is commonly used in medicine chemical reagents. Molecular recognition refers to the ability to distinguish and combine host molecules that can complement each other in a complex mixture of liquids by relying on characteristics such as shape, size, and chemical function. As a commonly used chemical reagent, the distinction between o-vanillin is an unavoidable problem in daily work. Molecularly imprinted polymers of o-vanillin are the main ways to achieve this distinction. In this paper, the use of UV-initiated in situ polymerization method to prepare a support film o-vanillin molecular imprinted polymer film. The structure and surface structure of molecularly imprinted polymer films were measured by Fourier transform infrared spectroscopy. Through the relevant experiments, molecularly imprinted polymeric films can still exhibit good selective transmission performance under the influence of interfering substances.
