These two molecules showed impressive charge In ﬁnal form 25 January 2018 carrier mobility due to better packing that are facilitated by quadrupoles. We hypothesized that the Available online 2 February 2018 copolymers of these monomers would also exhibit high charge carrier mobility. However, we envisioned that the dihedral angle at the connecting point between the monomers will play a crucial role in packing Keywords: as well as charge transport.
