Abstract

With amazing optical and electrochemical properties, the benzothioxanthene imide, a sulfur containing rylene, has only recently been demonstrated as a promising building block for organic electronics. As a result, the seminal synthetic procedure, published almost 50 years ago, has never been amended nor revisited so far. Given the great potential of this dye and numerous application perspectives, we thus report herein a significant update and modernization of its synthesis.
