J. Yamada et al., PREPARATION AND ELECTRICAL-PROPERTIES OF RADICAL-CATION SALTS BASED ON 1,3-DITHIANE DERIVATIVES, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 296, 1997, pp. 53-59
Preparation of radical cation salts based on 1,3-dithiane derivatives
(1,2 and 5-8) was investigated. Although attempts to prepare stable ra
dical cation salts derived from 1 and 2 were unsuccessful, various rad
ical cation salts composed of TTF (tetrathiafulvalene) derivatives fus
ed with a 2-(1,3-dithiol-2-ylidene)-1,3-dithiane (DTDT) unit (5-8) wer
e formed with ease by electrochemical oxidation. Several radical catio
n salts of 6-8 exhibited metallic conducting behaviors on a single cry
stal or compressed pellets.
