• -film transistors (OTFTs), or organic photovoltaics (OPVs) [1][2][3]. Concerning applications, organic materials are highly attractive due to their low cost and their particularly simple deposition from either vacuum or solution (casting or printing), and thus they are already utilized in industrial

• photocurrent generation also from respective low-energy photons and thus enhancing the overall light harvesting yield in organic photovoltaics (OPV). For example, in the field of fused N- and S-heterocycles, thieno[3,4-b]pyrazines with various side groups have already found applications in OPVs [5][6][7][8

• peripheral flexible side groups that point outward [13][14][15][16]. They can be used for a variety of different optic and electronic applications, for example as materials for photovoltaics (in the columnar phase) [17][18][19] or as compensation layers in display technology (in the nematic phase) [20][21
