The condensation reaction of dithiocarbonates derived from azuleno-and guaiazulenopentathiepin with vinylene trithiocarbonate and the ethylenedithio derivative in triethyl phosphite afforded azulene-based tetrathiafulvalenes [Az-TTF, Az-(EDT)TTF, GAz-TTF and GAz-(EDT)TTF], respectively. The vinylene derivatives (Az-TTF and GAz-TTF) showed slightly higher electron-donating ability than the corresponding ethylenedithio ones [Az-(EDT)TTF and GAz-(EDT)TTF] by CV measurement. GAz-TTFs produced charge transfer complexes with tetracyanoquinodimethane, respectively.
