US 2002/0163774 A1 · TCNQ complex and its application in solid electrolytic capacitors

Abstract

The present invention discloses TCNQ complex, shown as the following formula: 1 wherein X represents identical or different double electron donors, TCNQ represents tetracyanoquinodimethane. The TCNQ complex is prepared by synthesizing TCNQ with double electron donors as the major composition. Different ratios between compositions can be adjusted based on the distinct properties of various electron donors to conform to different needs of manufacturing process. The TCNQ complex of the present invention is resistant to high voltage and high temperature. Its melting point is higher than the soldering temperature. In addition, the TCNQ complex has better conductivity that remains even after the heating/cooling cycle.
