Filed:

Oct 20, 2005

Appl. No.:

11/256281

Inventors:

Christopher P. Gerlach - Saint Paul MN, US

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

H01L 51/40
C07D 333/02

US Classification:

438 99, 257 40, 257E51006, 549 29, 252500

Abstract:

Acene-thiophene compounds are disclosed that are useful as organic semiconductors. The compounds, when used as the semiconductor layer in organic thin-film transistors 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.

International Classification:

H01L 29/08

US Classification:

257 40, 438 99, 257E51029, 257E51036

Abstract:

Electronic devices that include an acene-thiophene copolymer and methods of making such electronic devices are described. More specifically, the acene-thiophene copolymer has attached silylethynyl groups. The copolymer can be used, for example, in a semiconductor layer or in a layer positioned between a first electrode and a second electrode.
