Optical study on bis(propylenedithio)tetrathiafulvalenium (BPDT-TTF) salts

First nanoparticles of Bechgaard salts

“…These three characteristic absorptions appear at similar positions for numerous organic conductors [19]. For instance, they are located at $ 13500 cm À1 (strong), $ 18400 cm À1 (weak), and $ 22400 cm À1 (strong) for (BPDT-TTF) 3 (PF 6 ) 2 (BPDT: bis(propylenedithio)tetrathiafulvalene) [20]. Finally, preliminary room temperature conductivity measurements on nanoparticle powders give values of about 0.2 S/cm, of the same order of magnitude than those for bulk powder materials.…”

“…1(a)], 1D columnar structures are formed in the BPDT-TTF-based charge transfer salts because the steric effects due to the propylene groups prevent 2D molecular arrangements as in the case of the BEDT-TTF-based salts. Syntheses of several BPDT-TTF-based charge-transfer salts have been reported so far [13][14][15][16][17][18][19][20][21][22], but the electronic properties have not yet been investigated in detail.…”
