Abstract
Bis(2-acenyl)acetylene compounds that are useful as organic semiconductors are disclosed. The compounds, when used as the active layer in OTFTs exhibit device characteristics, like charge-carrier mobilities and current on/off ratios, that are comparable to those of pentacene. Also described are semiconductor devices comprising at least one compound of the invention; and articles comprising the semiconductor devices such as thin film transistors or transistor arrays, and electroluminescent lamps.
Claims25

- in an amount from about 50 to 100% of said interpolymerized units;
- and from 0 to about 50% of said interpolymerized units according to the formula:
- wherein each R1 and R2 comprises, independently, a group selected from hydrogen;
- C1–C20 aliphatic;
- chloro;
- bromo;
- carboxy;
