Bis-substituted tetrathiapentalenes — Novel building blocks for extended tetrathiafulvalenes and conducting polymers
摘要:
1,3,4,6-tetrathiapentalene-2,5-dione (1) reacts in a Wittig-type fashion with aromatic/aliphatic aldehydes 2a - h upon heating in neat triethyl phosphite to bis-substituted tetrathiapentalenes (3a - h), which can be oligo-/polymerized oxidatively to give vinylogous TTF derivatives or highly conducting,polymeric solids (sigma(RT) = 1 S/cm), respectively.
