【Abstract】 Organic thin film transistors offer a potential entry route into new, inexpensive organic electronics for a variety of applications including large-scale flexible displays, and large-area sensor arrays. Organic semiconductors based on extended aromatic systems are growing in importance as components for electronic devices. Much attention has been devoted to pentacene, as it is the best organic semiconductor, showing the highest mobilities and on/off ratios in thin film transistors for p-type semiconductors. Despite its promise, pentacene does present limitations in terms of processability owing to its extremely poor solubility and its instability in solution. Our goal is to improve its solubility and stability using proper chemical modification. A series of new pentacene analogues have been designed and synthesized. Thin film transistors based on these molecules have been successfully fabricated using solution process.更多还原
