Extended bis-fused tetrathiafulvalenes incorporating a heteroaromatic pi-electron spacer
New pi-electron donors are being sought for the preparation of organic conductors. The first synthesis of bisfused pi-electron donors incorporating a heteroaromatic pi-electron spacer (see Figure) is reported. The electrochemical properties of 3a-e and 4a-e and the crystal structure of 3e ate presented, the results for the TCNQ complexes 3a and 4a confirming that the fusion of two donor units is a suitable strategy forthe development of highly conducting molecular complexes.
