  • Patent number: 8258501
    Abstract: A method of using a metal complex as an n-dopant for doping an organic semiconducting matrix material in order to alter the latter's electrical characteristics is provided. In order to provide n-doped organic semiconductors with matrix materials having a low reduction potential, while achieving high conductivities, the n-dopant is a neutral electron-rich metal complex with a neutral or charged transition metal atom as a central atom and having at least 16 valence electrons. The complex can be polynuclear and can possess at least one metal-metal bond. At least one ligand can form a ? complex with the central atom, which can be a bridge ligand, or it can contain at least one carbanion-carbon atom or a divalent atom. Methods for providing the novel n-dopants are provided.

  • Patent number: 8227029
    Abstract: Method for depositing a vapour deposition material on a base material, in particular for doping a semiconductor material, in which a vapour deposition batch, in which the vapour deposition material is enclosed in an air-tight manner by a shell, is introduced into a vapour deposition chamber and the shell is opened in the vapour deposition chamber, so that the vapour deposition material in the vapour deposition chamber then evaporates and is deposited on the base material, wherein the shell is opened by at least partially melting by heating a meltable shell material which at least partially forms the shell at a melting temperature which is lower than an evaporation temperature of the vapour deposition material.
