A New BEDT-TTF-Based Organic Charge Transfer Salt with a New Anionic Strong Acceptor, N,N'-Disulfo-1,4-benzoquinonediimine
نویسندگان
چکیده
A novel organic dianion, N,N'-Disulfo-1,4-benzoquinonediimine (1) has been prepared, which is a strong electron acceptor. The reduction potential of the PPh4 salt indicates that 1 is a stronger acceptor than DDQ (2,3-dichloro-5,6-dicyano-1,4benzoquinone). The dianionic acceptor provided a BEDT-TTF salt, (BEDT-TTF)41·3H2O, the structures and physical properties of which are reported.

A new ferrocene-containing charge-transfer salt, (TTF)2(Fe(C5H4-CH(CH3)NHCOCH2SO3)2)
A novel ferrocene-containing dianion, Fe(C5H4-CH(CH3)NHCOCH2SO3 – )2 (1), has been prepared. The oxidation potential of the PPh4 salt is +0.35 V (vs. SCE in PhCN), indicating that it is a stronger donor than TTF (tetrathiafulvalene) by +0.03 V. The dianion provided a TTF salt, the structure and physical properties of which are reported. Over the past three decades a growing subject in the field...
متن کاملA Novel BEDT-TTF-based Purely Organic Magnetic Conductor, α-(BEDT-TTF)2(TEMPO-N(CH3)COCH2SO3)·3H2O
A new BEDT-TTF-based salt with an organic free radical TEMPO has been prepared. The salt consists of alternate layers of conducting and magnetic sheets, between which are short S(BEDT-TTF)...O(TEMPO) contacts. The magnetic susceptibility is well modelled by the combination of a Curie-Weiss and a 2-D Heisenberg models with J = -89 K and θ = +0.05 K.
متن کاملOrganic charge-transfer phase formation in thin films of the BEDT-TTF/TCNQ donor-acceptor system
We have performed charge transfer phase formation studies on the donor/acceptor system bis(ethylendithio)tetrathiafulvalene (BEDT-TTF)/tetracyanoquinodimethane (TCNQ) by means of physical vapor deposition. We prepared donor/acceptor bilayer structures on glass and Si(100)/SiO2 substrates held at room temperature and analyzed the layer structures by optical microscopy, X-ray diffraction and focu...
متن کاملTheory of Photoinduced Phase Transitions in Molecular Conductors: Interplay Between Correlated Electrons, Lattice Phonons and Molecular Vibrations
Dynamics of photoinduced phase transitions in molecular conductors are reviewed from the perspective of interplay between correlated electrons and phonons. (1) The charge-transfer complex TTF-CA shows a transition from a neutral paraelectric phase to an ionic ferroelectric phase. Lattice phonons promote this photoinduced transition by preparing short-range lattice dimerization as a precursor. M...
متن کاملElectron-Transfer Boat-Vibration Mechanism for Superconductivity in Organic Molecules Based on BEDT-TTF
The highest T, organic superconductors all involve the organic molecule bis(ethy1enedithio)tetrathiafulvalene (denoted as BEDT-TTF or ET) coupled with an appropriate acceptor. This leads to ET, ET+, or (ET)2+ species in the crystal. Using ab initio Hartree-Fock calculations (6-31G** basis set), we show that ET deforms to a boat structure with an energy 28 meV (0.65 kcallmol) lower than that of ...
