  • Tetrathiapentalene and tetraselenapentalene compounds
    Patent number: 4089857
    Abstract: This application is concerned with tetrathiapentalene and tetraselenapentalene compounds. Specifically, it is concerned with 1, 3, 4, 6-tetrathia-2, 5-dihetero-pentalene and 1, 3, 4, 6-tetraselena-2,5-dihetero-pentalene compounds having the formula ##STR1## wherein X is S or Se; each of Y.sup.1 and Y.sup.2 is O, S, or Se; each of Z.sup.1 and Z.sup.2 is --SR, SeR or ##STR2## wherein R and R.sup.I are H, alkyl, aryl, or together form a ring of carbon atoms; and An is the anion of a strong acid. These compounds are key synthetic intermediates for the preparation of tetrathiafulvalene and tetraselenafulvalene materials.

  • Process of optically printing highly conductive character utilizing a medium containing a halogenated hydrocarbon photoactivator and a tetrathiafulvalene or a related compound thereof
    Patent number: 4082552
    Abstract: A method of optically printing conductive characters using charge transfer compounds is provided. The method is characterized by depositing an organic .pi. electron donor compound dissolved in a halogenated hydrocarbon (halocarbon) on a suitable substrate and selectively exposing the so coated substrate to actinic radiation to obtain a permanent, highly conductive, image.
