A semiconductor composition which comprises a soluble polyacene semiconductor and a polymeric semiconducting binder the binder having a permittivity greater than 3.4 at 000 Hz. The charge mobility of the semiconducting binder when measured in a pure state is greater than 10cm/Vs and more preferably greater than 10cm/Vs. Organic thin film transistors in which the source and drain electrodes are bridged by the semiconductor composition have desirable properties of reproducibility and charge mobility. The organic semiconducting composition can be applied by solution coating.

Transistors and methods for making them

This invention comprises a semiconducting polymer having a permittivity greater than 3.4 at 1000 Hz and a charge mobility in the pure state greater than 10cmVsand more preferably greater than 10cmVs. Preferred polymers include repeating units of triarylamines which have specific cyano and/or alkoxy substitution. They are suitable for use in electronic components such as organic thin film transistors.
