【Abstract】 Thioxanthone(TX)and its derivatives have excellent absorption properties in the near ultraviolet range and high hydrogen abstraction capacity. Here, the one-component water-soluble thioxanthone with a tertiary amine was designed and synthesized. The maximum absorption peak of its UV-Vis absorption spectrum is at ca. 400 nm, which has a red shift of 15 nm compared to that of commercial 2,4-diethyl-9 H-thioxanthen-9-one(DETX). The molar extinction coefficient reaches 104 orders of magnitude and exhibits the good light absorption acpacity. Photolysis studies have shown that it has photobleaching properties. This photoinitiator also has good solubility in alcohol and water.更多还原
