Paragraph 0149-0152, (2021/03/30)
The invention relates to a cyclopentadienopyrazine organic compound and application thereof. The organic compound has a structure as shown in a general formula (1). The organic compound according to the present invention has excellent hole transport properties and stability, can be used as a hole injection layer material in an organic electroluminescent element, and can also be doped in a hole injection layer or a hole transport layer as a doping agent, so that a device can be driven at a low voltage, the electroluminescent efficiency can be improved, and the service life of the device can beprolonged.

A process to manufacture substituted tetracyano-hexaazatricyclics with the substitutions occurring at the 9 and 10 hydrogens. The process begins with 2,3-dichloro-5,6-dicyanopyrazine, which is reacted to form the desired tetracyano-hexaazatricyclic. Different process embodiments enable different reaction paths to the desired tetracyano-hexaazatricyclic. Different tetracyano-hexaazatricyclic embodiments include bis(2-methoxyethyl)-2,3,6,7-tetracyano-1,4,5,8,9,10-hexazaanthracene and bis(2-methoxyethoxyethyl)-2,3,6,7-tetracyano-1,4,5,8,9,10-hexazaanthracene.

Four novel S-substituted 4,5-disulfanylpyrazine-2,3-dicarbonitriles have been obtained in a multistep synthesis from diaminomaleonitrile. Two of these dicarbonitriles, with ethyl or benzyl S-substituents, give pure magnesium azaphthalocyanines in good yields when reacted with magnesium propoxide in propanol and dioxane. Aromatic S-substituents are less stable during the reaction conditions used for cyclisations, and product mixtures are obtained. Acta Chemica Scandinavica 1996.
