Dimensionality and Electrical Properties in Organic Synthetic Metals—Current Results through Selected Recent Examples

Effect of light irradiation on the gas sensor characteristics of the SnO2 and ZnO modified by tetrathiafulvalene derivative

“…The TTF and its derivatives have been intensely studied because of their abilities to form organic metals and superconducting solids [18,19]. During the last decade, a particular attention has been devoted to the design of TTF donors involving a π-extended system [19,20] known to stabilize the metallic state [19,21].…”

“…During the last decade, a particular attention has been devoted to the design of TTF donors involving a π-extended system [19,20] known to stabilize the metallic state [19,21]. Thus, TTF derivatives incorporating aromatic substituents [22,23] and dimeric TTFs linked by different aromatic conjugated spacers [24,25] were successfully used to form highly conducting solids [26,27].…”

Donor–acceptor complex of a new bis-TTF donor containing a pyridine diester spacer with TCNQ as the acceptor: a disappointing system

“…It is now clearly established that the metallic state observed in organic conducting materials of the TTF type (TTF is tetrathiafulvalene) (Fabre, 2002) can be strongly stabilized by increasing their structural and electronic dimensionality (Williams et al, 1992;Fabre, 2000). Such a result can be attained by introducing, on the TTF ring, a functional group able to provide supplementary molecular interactions (Batsanov et al, 1995;Heuzé et al, 2000;Legros et al, 2000;Lorcy et al, 2009).…”

A bi-TTF with a bipyridine spacer: 4,4′-bis[(3,6,7-trimethylsulfanyltetrathiafulvalen-2-yl)sulfanylmethyl]-2,2′-bipyridine

“…For general background, see: Yagubskii (1993); Williams et al (1992); Sakata et al (1998); Fabre (2002). For coordination complexes of TTF with nitrogen aromatic substituents, see: Setifi et al (2003); Liu et al (2003); Boudiba et al (2005).…”
