Abstract
The synthesis and electrochemical properties of di- and tetra-halogenated t etraselenafulvalene (TSF) derivatives are presented. The synthetic method i nvolves an efficient formation of halogen substituted 1,3-diselenole-2-selo nes from readily available starting materials. Electrochemical crystallizat ion afforded several radical cation salts, and, of them, the ClO4 salt of t he dimethyl-dibromo-TSF showed a high conductivity of 400 S cm(-1) at room temperature and retained metallic down to ca. 90 K.
