the core in a single operation, thus making the syntheses highly convergent. In the cases of the larger functionalized systems, alkyl substituents on the thiophenes afford soluble materials. In order to prepare the molecules with >50 Å lengths, an iterative divergent/convergent approach had to be utilized for the construction of oligo(thiophene-ethynylene) branching arms.

and BTIDT-OC12, have been designed and synthesized for solution-processed, small-molecule organic solarcells (OSCs) donor materials. By optimizing the side chains, the hole mobility of the materials is modulated, which has been proven by the organic field-effecttransistor (OFET) performances. Solarcells based on BTIDT-C6 show a power conversion efficiency (PCE) of 4.83%. To the best of our knowledge
