Polymeric field-effect transistors (PFETs) are advancing rapidly in terms of their applications in low-cost large-area thin film transistors.To design new polymers for high-mobility PFETs with ambient-stability is still of great challenge. Herein, employing the concept of molecular docking, we design and synthesize several serials of conjugated copolymers for PFETs to investigate their structure-property relationship. We systematically compare FET device performances, polymer packings and film morphologies of the polymers, and find that this strategy is efficient to obtain high-performance FETs. By means of atomic force microscopy (AFM) and grazing-incident X-ray diffraction (GIXD), we investigate the morphology of all polymers in thin film to study the effect of polymer structure and also further to underdtand the relationship between device performance and the morphology of polymers in solid state. Fimally, we will obtain several commercially-available polymer materials for field-effect transistors.
