Tetrathiafulvalene; thiophene; synthesis; substitution effects; theoretical calculation.

Three Tetrathiafulvalene (TTF)-assembled thiophene molecules were synthesized with the different linkages of s bridge via Steglich esterification and classical SN₂ reaction. The results of UV and CV showed the different substitution effects existed in the new molecules formed by the molecule assembling. Among the new molecules, TTF-Th-2 (TTF-methylene-thiophene), linkage in the shortest s bridge, exhibited the most obvious substitution effects. Meanwhile, the result of theoretical calculation indicated that TTF-Th-2 exhibited lower bandgap with the evident electron transfer in the LUMO energy level.
