Outline of Final Research Achievements |
C3-symmetric molecules 1 and 2 were prepared via Sille coupling reaction between 2,5,8-tris(trimethylstannyl)benzo[1,2-b:3,4-b':5,6-b"]trithiophene and 2-(4H-thiopyran-4-ylidene)-4-bromo-1,3-dithiole (TPDT-Br) or 4,5-ethylenedioxy-4'-iodotetrathiafulvalene (EDO-TTF-I). Mixing and grinding 1 with TCNQ by the addition of small amount of acetonitrile and washing with acetonitrile afforded a charge transfer (CT) complex as black powder. The molecular charge of 1 was estimated as +1 by elemental analysis and vibrational spectroscopy. The electrical conducting and magnetic properties of CT complex were semiconducting behaviors. Theoretical analysis found that the charge is localized on one TPDT moiety of 1 upon one-electron oxidation. Therefore, molecule 1 has the charge of +1 with C1 symmetry, and shows the intramolecular charge disproportionation.
