Chemical and electrochemical investigations on thiazolium salts: A route to powerful donors in the dithiadiazafulvalene series

Abstract

Thiazolium salts have been investigated, chemically and electrochemically, in order to access to the redox properties of dithiadiazafulvalenes (DTDAF). As these donor molecules are oxygen-sensitive, it is more advisable to isolate them in their oxidized form as dicationic salts. Starting from a tetrathiazolium cation including two precursors groups, linked together with a conjugated spacer, a bis-DTDAF was formed and its electrochemical behavior studied.
