  • Patent number: 10128442
    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.

  • Publication number: 20170373251
    Abstract: The present invention relates to a process for preparation of an electrically doped semiconducting material comprising a [3]-radialene p-dopant or for preparation of an electronic device containing a layer comprising a [3]-radialene p-dopant, the process comprising the steps: (i) loading an evaporation source with the [3]-radialene p-dopant; and (ii) evaporating the [3]-radialene p-dopant at an elevated temperature and at a reduced pressure, wherein the [3]-radialene p-dopant is selected from compounds having a structure according to formula (I) wherein A1 and A2 are independently aryl- or heteroaryl-substituted cyanomethylidene groups, the aryl and/or heteroaryl is selected independently in A1 and A2 from 4-cyano-2,3,5,6-tetrafluorphenyl,2,3,5,6-tetrafluorpyridine-4-yl, 4-trifluormethyl-2,3,5,6-tetrafluorphenyl, 2,4-bis(trifluormethyl)-3,5,6-trifluorphenyl, 2,5-bis(trifluormethyl)-3,4,6-trifluorphenyl, 2,4,6-tris(trifluormethyl)-1,3-diazine-5-yl, 3,4-dicyano-2,5,6-trifluorphenyl, 2-cyano-3,5,6-trifluorpyridi

  • Patent number: 8764462
    Abstract: The invention concerns a semiconductor component with a layered arrangement with an electrode, an organic semiconductor layer, an injection layer, and an additive layer, which consists of an additive, which on contact with the molecular doping material modifies its doping affinity with respect to the organic material of the organic semiconductor layer, wherein in the injection layer a layered region is formed with a first doping affinity of the molecular doping material with respect to the organic material and a further layered region is formed with a second, in comparison to the first doping affinity smaller, doping affinity of the molecular doping material with respect to the organic material. Furthermore the invention concerns a method for the manufacture of a semiconductor component and also the application of a semiconductor component.
