  • Semiconductor compounds
    Patent number: 9406886
    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 cm2V?1s?1 and more preferably greater than 10?6 cm2V?1s?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.
