| Research Abstract |
π-extended heteroarenes and(ii) donor-acceptor(D-A) structure in the polymer backbone. As the approach(i), naphthodithiophene(NDT)-based polymers are synthesized, and as the approach(ii), benzobisthiazole(BBTz), naphthobisthiadiazole(NTz), and quinacridone(QA)-based polymers are synthesized. All these polymers form highly crystalline structures in the thin film with narrowπ-stacking distances of 3. 5~ 3. 6 A, and they exhibit high charge carrier mobilities of 0. 3~ 0. 8 cm2/ Vs, which are very high for semiconducting polymers. These results prove that the proposed approaches are quite effective for the creation of high performance semiconducting polymers.
