Syntheses and Properties of Novel Dimeric Tetrathiafulvalenes Linked with an Ethenylene or Ethynylene Spacer

Abstract
Conjugated dimeric TTFs linked with an ethenylene or ethynylene spacer were prepared as novel electron donors and preferentially formed 1:1 complexes with TCNQF4 and with DDQ, which were more conductive than those of monomeric TTFs.
