Organic semiconductors are described having an electron donating cation which is a Group VIa element derivative of a polycyclic aromatic hydrocarbon and an inorganic or organic electron-accepting anion. These materials are generally soluble in ordinary solvents and have resistivities between 10.sup.-.sup.3 and 10.sup.9 ohm-cm. They are useful in conducting coatings, fibers, etc.
Novel 5,6,11,12-tetraselenotetracene-o-chloroanil complexes are disclosed which exhibit improved electrical conductivity, and low resistivity at room temperature. Said complexes are useful, e.g., as organic electrical conductors, solid state devices, and for providing antistatic coatings.
A field-effect transistor includes a channel-forming region composed of an organic compound crystal including .pi.-electron conjugated molecules each containing chalcogen atoms as a constituent, wherein the distance between chalcogen atoms of adjacent .pi.-electron conjugated molecules is short, and the organic compound crystal has a periodic structure in which .pi.-electron conjugated molecules are two-dimensionally or three-dimensionally linked together.
5162557 - Ruthenium aromatic polycarboxylates - Owned by Synthetic Products Company (Cleveland, OH) [*] Notice:The portion of the term of this patent subsequent to June 25, 2008 has been disclaimed.
Ruthenium aromatic polycarboxylates from the class consisting of ruthenium isophthalate, ruthenium trimesate, ruthenium trimellitate, ruthenium pyromellitate and ruthenium 5-sulfonate-1,3-isophthalate have been prepared and have been found to be especially suitable as semiconductors.
An organic light emitting device (10) is provided which is encapsulated by a Siloxane buffer layer (17.1). This Siloxane buffer layer (17.1) is applied to the diode (10) providing for protection against contamination, degradation, oxidation and the like. The Siloxane buffer layer (17.1) carries at least a second encapsulation layer (17.2).
