Abstract
The invention concerns an insulator for an organic electronic component, in particular, for an organic field-effect transistor (OFET) or for an organic capacitor. The insulating material is characterized in that it includes an almost constant relative dielectric constant, even in case of frequency variation in wide ranges, for example, between 1 Hz and 100 kHz.
