  • Strongly magnetic organic solid state composition of matter
    Patent number: 4803006
    Abstract: The present invention is an organic composition of matter having paramagnetic or ferromagnetic properties, wherein the composition includes a donor molecule and an acceptor molecule in a mix-stacked form and a dopant with an electron affinity so as to generate a ground state molecule with an appreciable triplet character. Also included is a method for preparing such a composition of matter.

  • Process for preparing tetraselenofulvalenes, and conductive salts obtained therefrom
    Patent number: 4246173
    Abstract: A multistep process for preparing tetraselenofulvalenes involving the synthesis of 1,3-diselenole-2-selones and -2-thiones from diselenocarbamates and .alpha.-haloketones followed by coupling of the selone or thione using a dechalkogenizing reagent. New highly conductive salts obtained by coupling certain tetraselenofulvalenes with acceptor compounds are also disclosed.
