Abstract
The double-bridged tetraselenafulvalenophanes (TSF-phanes, 4) were efficien tly synthesized by a new method using the deprotection/realkylation sequenc e of the TSF bisthiolate building block jr. Electrocrystallization of 4b wi th the Au(CN) counter-anion gave a radical cation salt that showed a very h igh conductivity of 53 S cm(-1) at room temperature. X-ray crystallographic analysis revealed that the crystal structure contained many intra- and int ermolecular Se-Se contacts; favorable for high conductivity.
