一种高疏水性吩噻嗪光敏剂及其制备方法和应用

本发明提供了一种高疏水性吩噻嗪光敏剂及其制备方法和应用，属于精细化工技术领域，光敏剂以吩噻嗪阳离子染料骨架为核心，在3,7位二乙醇胺取代侧链末端四个羟基均经5‑苯基戊酸酯化形成盐类化合物。通过在母核外围引入四条含芳香基团的柔性酯化侧链，该结构修饰可使化合物相较四羟基封端中间体的计算辛醇/水分配系数（cLogP）显著提升，形成高疏水性分子结构，从而增强其在有机介质中的溶解性、分散稳定性和溶剂适配性。该化合物可在二甲亚砜、甲醇、乙醇、乙腈和二氯甲烷等有机溶剂中使用，表现出近红外吸收和发射特性，并可在红光照射下产生单线态氧，适用于有机相光氧化反应及荧光成像或荧光示踪。
