홈페이지논문 초록 (Abstract)
In this work, the photoinduced optoelectronic properties of a conjugated polymer from device characterization and quantum calculations have been studied. It was demonstrated that th e photosensitive conjugated polymer with electron donor-accep tor dyad (6) which contains a terthiophene unit, can modulate charge acc umulation by photoirradiation resulting in a threshold voltage shift in the polymer field-effect transistors (PFETs) while this effect of the photoinactive polymer (5) containing a thieno-thiophene unit is negligi ble. These results suggest that the feasible molecular design strate gies can provide an effective platform to achieve controllable thr eshold voltage modulation in PFETs. (C) 2017 Elsevier Ltd.
