Abstract
Process for the preparation of a benzodithiophene compound which comprises reacting at least one monohalogenated dithiophene compound with at least one internal alkyne. Said benzodithiophene compound, after suitable functionalization and polymerization, can be advantageously used in the construction of photovoltaic devices such as, for example, photovoltaic cells, photo-voltaic modules, solar cells, solar modules, on both rigid and flexible supports. Furthermore said benzodithiophene compound can be advantageously used as spectrum converter in luminescent solar concentrators (LSC). Said benzodithiophene compound can also be advantageously used as precursor of monomeric units in the preparation of semiconductor polymers.
