Considerable research efforts with increased interests in both academic and industrial institutions for organic semiconductor have been devoted to the improvement of polymer-based organic thin film transistors (OTFTs) and polymer solar cells (PSCs) by solution processes. In this study, a series of p-type polymers with enforced coplanar structure for effective π-electron delocalization, naphtho[2,1-b:3,4-b']dithiophene and thiophenes as main core units, PNDT-T, PNDT-TT and PNDT-TTT, were successfully synthesized by stille coupling reaction. Naphtho[2,1-b:3,4-b']dithiophene unit of the polymers main chain enhances charge carrier mobility by extending π-conjugationlength and rigidly enforced coplanar structure. |
