Several derivatives of 1,3-dithiole[3]dendralene derivatives with two thiophene spacers (2) were synthesized. The results of an X-ray structure analysis of an analog without fused TTF units and a DFT calculation of the unsubstituted-2 (2Aa) suggested that 2Aa had a structure with significantly distorted between the central 1,3-dithiole (DT) ring and one of the thiophene rings.
