radical polymerization. TX-DPA has an excellent absorption character in the visible region and the photophysical properties of TX-DPA were investigated by fluorescence and laser flash photolysis studies and the photopolymerization of methyl methacrylate in air atmosphere helped to understand the initiation mechanism of TX-DPA. Moreover, it is possible that the production of singletoxygen from the
合成了7,12-二苯基-14 H-萘[2,3 - b ]噻吨黄酮-14-一(TX-DPA),并将其表征为潜在的可见光光引发剂,用于自由基聚合。TX-DPA在可见光区域具有良好的吸收特性,通过荧光和激光闪光光解研究了TX-DPA的光物理性质,甲基丙烯酸甲酯在空气中的光聚合有助于理解TX-DPA的引发机理。此外,由分子氧淬灭3 TX-DPA可能产生单线态氧,导致单线态氧与TX-DPA反应形成内过氧化物:内过氧化物的分解导致引发自由基。
