Abstract

An organic, semiconducting material, in particular, a material which can be used as a semiconductor material in organic electronics. A component of the material thereby comprises the oligophenylene from heterocyclic parent compounds with the following structure:

Claims (6)

1. An organic charge transport material, with which electrons and holes can be transported equally well, wherein in a layer of undoped material, with a thickness of 150 nm, a measurable current density of larger than/equal to 0.5 A/cm 2 is exhibited at 0.25 V,

wherein the charge transport material comprises an oligophenylenes compound from heterocyclic parent compounds with the following structure

2. The charge transport material according to claim 1 , wherein the material is transparent in thin films.

3. The charge transport material according to claim 1 , which is present as a mixture.

4. The charge transport material according to claim 1 , which is present n- or p-doped.

5. An organic electronic component with a semiconducting layer and/or a conductive layer comprising the charge transport material according to claim 1 .
