A new series of thioxanthylium trifluoromethanesulfonates has been synthesized via a trifluoromethanesulfonic-acid-induced cyclization of thioether precursors. The electronic structure of these thioxanthylium salts were determined by UV−vis absorption spectroscopy, and theoretically investigated by density functional theory calculations.

硫氧蒽鎓支架的电子结构

通过三氟甲磺酸诱导的硫醚前体环化反应，合成了一系列新的三氟甲磺酸噻吨鎓盐。这些硫杂蒽鎓盐的电子结构通过紫外可见吸收光谱法确定，并通过密度泛函理论计算进行理论研究。
