APPLICATION OF ULTRA HIGH PRESSURE TO A STUDY OF ORGANIC SEMICONDUCTORS.
Abstract
The electrical conductivity measurement apparatuses for organic compounds under the pressure range of 1 to 40,000 atmospheres and at various temperatures (25 - 400C) were developed. The effects of pressure and temperature on the electrical conductivity of organic compounds such as ferrocene, nickelocene, tetrathioteracene-o-chloranil, cobaltocene 3,3', 5,5'tetrabromo p-diphenoquinone and durene diaminechloranil complexes were investigated. The effect of pressure on the electrical properties of the organic solids is discussed. Some theoretical considerations on the effects of the structure of organic compounds were made. The infrared spectrum measurement of organic compounds under pressure was also studied. The results indicated the molecule became closed together and bonding charge transfer complexes tended to form dative bonding. Compressibility and single crystal growth of organic compounds with heating under pressure were attempted. (Author)
