7,7,8,8-Tetracyanoquinodimethane and Its Electrically Conducting Anion-Radical Derivatives

Water-controlled synthesis of low-dimensional molecular crystals and the fabrication of a new water and moisture indicator

“…The columns exhibited typical peaks at 2196, 2178, and 2167 cm 1 , while the peaks for the lamellae were located at 2219 and 2178 cm 1 (Inset in Fig. 3(a)), confi rming the different phases of the columns and lamellae.…”

Development of Conductive Organic Molecular Assemblies: Organic Metals, Superconductors, and Exotic Functional Materials

“…In 1968, Ginzburg extended Little's 1D model to a 2D model, 171 since the 1D system has instability inherent to low-dimensionality. 172 The most extensively studied acceptor molecule is TCNQ, prepared in 1960 by Acker et al, 173 while the corresponding donor is TTF, prepared in 1970 by Coffen 174 and Wudl et al 175 In 1973, the first organic metal TTF Á TCNQ was synthesized by Ferraris et al 176 and Coleman et al 177 Since then, more than two thousand metallic and highly conductive organic CT complexes have been synthesized. 3.1 Donor-Acceptor (DA) Complexes.…”

The crystal structure of N-methylphenazinium tetracyanoquinodimethanide

“…in these salts is quite large, including values from about 100 ohm-lcm -1 to 10 -12 ohm-lcm -1 at room temperature (Acker, Harder, Hertler, Mahler, Melby, Benson & Mochel, 1960;Melby, Harder, Hertler, Mahler, Benson & Mochel, 1962). With few exceptions the more conductive salts are 'complex', containing both formally neutral and formally negative tetracyanoquinodimethan (hereafter TCNQ).…”
