A new class of extended tetrathiafulvalene cruciform molecules for molecular electronics with dithiafulvene-4,5-dithiolate anchoring groups

Cruciform motifs with two orthogonally oriented π-extended tetrathiafulvalenes and with differently protected thiolate end-groups are synthesized by stepwise coupling reactions. The molecules are subjected to single-molecule conductivity studies in a break-junction and to conducting probe atomic force microscopy studies in a self-assembled monolayer on gold.
