487 ELECTRICAL PROPERTIES OF IODINE COXPLEXES OF ASPHALTENES Gustave A. Sill and Teh Fu Yen Mellon Institute I Pittsburgh, Pennsylvania 152 13 INTRODUCTION Polynuclear aromatic hydrocarbons generally form charge-transfer complexes with halogens. Some of the fused aromatic hydrocarbons, e.g., perylene, violanthrene, yield solid complexes exhibiting extremely good semiconduction (l,2,3) while others, e.g., coronene, show only fair to poor semiconduction (4). A number of charge-transfer complexes of aromatic containing polymers have been investigated for possible differences in electrical properties (5,6,30). A polymeric dielectric may be converted to a polymeric semi- conductor by increasing the aromaticity of the insulator, followed by complex formation with a halogen (7,8). The increase in aromaticity can be effected by radiation--e.g., cyclization of polyethylene and followed by dehydrogenation (7); or by heat--e. g., pyrolysis or graphitization to a pyropolymer (8). lhe resulting products when treated with iodine exhibit a wide range of interesting electrical properties. From a structural standpoint asphaltenes (9) are considered to consist of two-dimensioned fabrics of condensed aromatic rings, intermingled with short aliphatic chains and fused naphthenic ring systems (10). diffraction (11,12) and ESR investigations (13) have indicated that these aromatic oyotemo tend to form otacko of graphite-like lryrro rurroundrd by a disorganized zig-zag chain structure of saturated carbons. they may be considered as a highly associated "multipolymer" (14), the X-ray Morphologically
