In this study, an π-conjugated polymer semiconductor, PBDTTTffPI, is newly synthesized to satisfy the requirements of the organic semiconductor inks suitable for electrohydrodynamic (EHD) jet printing technology. Bulky alkylation and fluorine-functionaliztion to the polymer allows PBDTTTffPI to display good solubility in several organic solvents. The EHD printing of this higly soluble PBDTTTffPI ink produces direct patterns of polymer semiconductors, while maintaining smooth surface morphologies and crystal structures similar to the spin-coated films. Finally, we investigate its feasibility of use as the active layer in organic field-effect transistors (OFETs) and logic gates. |
