Abstract

Provided are processes for preparing an electrically doped semiconducting material that includes a [3]-radialene p-dopant. Also provided are processes for preparing an electronic device containing a layer that includes a [3]-radialene p-dopant. The processes may include (i) loading an evaporation source with a [3]-radialene p-dopant and (ii) evaporating the [3]-radialene p-dopant at an elevated temperature and at a reduced pressure. The [3]-radialene p-dopant may be selected from compounds having a structure according to formula (I) herein.
