ELECTROCHEMICAL REDOX BEHAVIOR AND ELECTROLUMINESCENCE IN THE MIXED ENERGY-SUFFICIENT SYSTEM THIANTHRENE AND -BIPHENYL)-5-(4-TERT-BUTYLPHENYL)-1,3,4-OXADIAZOLE

Efficient use of organic compounds in electroluminescent devices requi res detailed knowledge of their redox potential values and their abili ty to form stable radical ions, information available from electrochem ical investigations. The electrochemical behavior of the title compoun ds (TH and PBD) is described, followed by the preparation of light-emi tting diodes (LEDs) based on them. The characteristics of mixed single -layer and separated double-layer devices presented here suggest that PBD and TH could be useful for the construction of LEDs.
