• . Evidence is presented that the ability of these molecules to form one-dimensional hydrogen-bonded chains and subsequently exhibit hierarchical self-assembly into nanostructured domains can be correlated with improved device efficiency. Keywords: hydrogen-bonding; organic photovoltaics; self-assembly

• -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
