Donor-acceptor type polymers in which electron rich (donor), electron deficient (acceptor) are repeatedly connected to a polymer backbone, have attracted attention in many research fields due to their high electrical characteristic, however donor-acceptor type polymers have difficulties in application because of low solubility in organic solvents and high melting point. To overcoming this limit, we apply eutectic system to semiconducting polymers and enhanced electron mobility. By adjusting shearing force, semiconducting polymer chains are aligned uniaxially and crystallinity of semiconducting polymers is increased. we further have optimized epitaxial growth condition by controlling the phase separation rate within the microchannel. Consequentially this system, which can be easily processed at low temperatures (around 60 ℃) and increase the crystallinity, opens up the possibility of device application for donor-acceptor type polymers.
