Abstract
Although less well known than their fully unsaturated analogues, dihydrotetrathiafulvalenes
(dihydro-TTFs) has been of considerable recent interest as components of organic conducting
materials. In this article, the various methods for their synthesis are reviewed and this is followed
by a survey of their structure and properties, including those of charge transfer salts, and an
account of their reactions.
