Abstract :

Starting from cyclopentadithiophene-benzothisdiazoles, we varied the side chains from hexadecyl to branched decyl-tetradecyl ones and further included linear cis and trans-alkenes which had a major influence on the backbone packing. We further concluded to strengthen the acceptor part upon introducing thiadiazoloquinoxalines leading to a lowering of the LUMO levels and more suited ambipolar character. Upon condensation of the diamino benzothiadiazoles with benzodithiophene-dione phenthrene-dione and phenanthroline-dione the acceptor part could be further strengthened and open a variety of new copolymers and small molecule acceptor structures.
