Abstract
The present invention relates to bis-thienobenzothienothiophene compounds and a process for their preparation. More in particular, the present invention relates to a new angular bis-thienobenzothienothiophene compound and the process for its preparation wherein said process comprises reacting at least one dihalogenated dithiophene compound with at least one terminal alkyne and the subsequent double annulation reaction. Said bis-thienobenzothienothiophene compounds can be appropriately functionalized and polymerized to produce electron donor compounds that can be advantageously used in the construction of photovoltaic devices or semiconductor polymers. Furthermore, said bis-thienobenzothienothiophene compounds, after functionalization, may be advantageously used as spectral converters in luminescent solar concentrators.
