| abstract |
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 10 −7 cm 2 V −1 s −1 and more preferably greater than 10 −6 cm 2 V −1 s −1 . 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. |
