Abstract

The double-bridged tetraselenafulvalenophanes (TSF-phanes, 4) were efficiently synthesized by a new method using the deprotection/realkylation sequence of the TSF bisthiolate building block 7. Electrocrystallization of 4b with the Au(CN)₂/^- counter-anion gave a radical cation salt that showed a very high conductivity of 53 S cm^-1 at room temperature. X-ray crystallographic analysis revealed that the crystal structure contained many intra- and intermolecular Se-Se contacts; favorable for high conductivity.
