Chemical and Electrochemical Investigations on Thiazolium Salts: a Route to Powerful Donors in the Dithiadiazafulvalene Series.
摘要:
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.
