“…Tetrathiafulvalene (TTF) derivatives are in turn, remarkable semiconductors for preparing devices as Field Effect Transistors [18][19][20][21][22] and the obtained results already point out the high potential of these materials, which can be easily procesed [23] and tailored synthesized. [24] Even though nanostructuration of TTF derivatives in different surfaces has been demonstrated, [25][26][27][28] potential applications of TTFs as component in circuitry do still require methods for precise nanoscale controlled position and/or manipulation of those molecules.…”

We present a process to fabricate molecule-based nanostructures by merging a bottom-up interaction and a top-down nanolithography. Direct nanoscale positioning arises from the attractive electrostatic interactions between the molecules and silicon dioxide nanopatterns. Local oxidation nanolithography is used to fabricate silicon oxide domains with variable gap separations ranging from 40 nm to several microns in length. We demonstrate that a ionic tetrathiafulvalene (TTF) semiconductor can be directed from a macroscopic liquid solution (1 M) and selectively deposited onto predefined nanoscale regions of a 1 cm 2 silicon chip with an accuracy of 40 nm.

We present a density functional theory (DFT) study on the reactivity of bis and tris (1,3-dithiole) TTF 1-4 by using B3LYP/6-31G (d,p) level. The possible electrophile and nucleophile attacking sites of the title compounds is identified using MEP surface plot study. Highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy gaps were calculated to explain the frontier molecular orbitals and to predict the quantum chemical descriptors. Local reactivity properties have been investigated using average local ionization energies and Fukui functions. Natural Bond Orbital analysis was computed and possible transitions were correlated with the electronic transitions. The calculated first hyperpolarizability (β 0) of bis and tris (1,3-dithiole) TTF molecules, indicates that investigated molecules might have not the NLO applications.

Organic conducting fiber‐like materials hold great promise for the development of nanowires that can act as connections in miniature electronic devices, as an alternative to inorganic nanometer scale structures. This article presents a conducting organic tetrathiafulvalene‐based supramolecular material which possesses a rich phase behavior with different packing of the molecules in the different forms, evidenced by electron spin resonance (ESR) spectroscopy. The distinct phases of conducting nanofibers can be easily fabricated through the temperature control of their preparation process from a xerogel by doping with iodine vapors. A total of four conducting phases have been identified conclusively using ESR spectroscopy as the key analytical tool. Three of the phases show a good long‐term stability and areas in which the I–V curves have ohmic behavior when studied by current sensing (conducting) AFM. They offer promise for applications where electrical nanometer scale connections are required.
