摘要:
Process for the preparation of a benzohetero[1,3]diazole compound disubstituted with heteroaryl groups which comprises reacting at least one benzohetero[1,3]diazole compound disubstituted with at least one heteroaryl compound. Said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can be advantageously used in the construction of luminescent solar concentrators (LSC). Furthermore, said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can be advantageously used in the construction of photovoltaic devices such as, for example, photovoltaic cells, photovoltaic modules, solar cells, solar modules, on both a rigid and flexible support. Said benzohetero[1,3]diazole compound disubstituted with heteroaryl groups can also be advantageously used as a precursor of monomeric units in the preparation of semiconductor polymers.
