摘要:随着高分子材料、光学器件及生物医用防护产品的迅速发展,紫外线吸收剂(UV Absorbers)在材料光稳定化、皮肤防护及光学防护等领域的重要性日益凸显。传统小分子紫外线吸收剂虽然具有良好的紫外防护能力,但普遍存在迁移性强、易挥发、环境持久性高及潜在生物毒性等问题。近年来,以Biginelli反应为核心合成的杂环化合物因其结构可调、功能多样及优异的光物理性能受到关注。1,2,3,4-四氢-6-甲基-4-苯基-2-硫代嘧啶-5-甲酸2-(甲基丙烯酰氧基)乙酯(简称“FRISK”)是一种典型的可聚合型硫代嘧啶类UV吸收剂,兼具紫外防护、抗氧化及良好生物相容性等特性。本文系统综述了紫外线吸收剂的发展背景、作用机理、该化合物的分子结构设计原理、合成路线、光物理性能、生物相容性研究以及其在高分子材料与生物医用领域的应用进展,并对未来研究方向进行了展望。
