Abstract |
The hydroxyl group containing polyimide (6FDA-HAB) was successfully synthesized with a simple one step condensation polymerization of the monomers 5,5'-(perfluoropropane-2,2-diyl) diisobenzofuran-1,3-dione (6FDA) and 3,3’-dihydroxy-4,4’-diaminobiphenyl (HAB). And then, the hydroxyl groups of polyimide (6FDA-HAB) were further reacted with 4-(1,2,2-trifluorovinyloxy)benzoyl chloride (TFVOB) using N-methylpyrrolidone (NMP) as solvent and trimethyl amine as base. A synthesized novel polyimide (6FDA-HAB-TFVOB) was fully soluble in common organic solvents and side chains of polyimides are easily connected into the hexafluorocylobutane form by simple thermal treatment. Thin film properties of a novel crosslinked polymide (6FDA-HAB-TFVOB) were systematically investigated such as chemical structures, surface roughness, surface morphology, surface energy and capacitance, etc. The pentacene thin film transistor with crosslinked 6FDA-HAB-TFVOB as a gate insulator showed a field effect mobility as 0.25 cm2/Vs with almost no hysteresis behavior. |
