Conducting organic solids

The bicycles 40-42 can all be considered as TTFs and as such may have potential as component molecules for conducting organic solids. In this respect, heteroatom intermolecular S- -N and S- -S contacts are of special interest since they may increase the dimensionality of aggregation in the solid state, and, accordingly, much effort has been directed toward structure determination of this family of molecules <1993SM(68)1914, 1997SM(86)1871,... 

A related area in which conducting organic solids play an important part, is the field of nonlinear optics. 

The possible applications of conducting organic solids in the fields of electronics and laser optics are manifold. 

Although the 1960s and 1970s were the most active decades of TCNQ research [82], there is still considerable interest in the magnetic and electrical properties of TCNQ salts. TCNQ was synthesized in 1962 as shown below [83]. Research in conductive organic solids developed rapidly with...

Results are described for three new highly conducting organic solids, all based on substituted TCNQ-derivatives TMTSF-2,5-dimethyl-TCNQ /TMTSF-DMTCNQ/ 1 1 shows "normal" conductivity vs.temperature behaviour, i.e. metallic conductivity at higher temperatures followed by a metal-semiconductor transition as the temperature is decreased below 5o K.

Dislocation theory as a portion of the subject of solid-state physics is somewhat beyond the scope of this book, but it is desirable to examine the subject briefly in terms of its implications in surface chemistry. Perhaps the most elementary type of defect is that of an extra or interstitial atom—Frenkel defect [110]—or a missing atom or vacancy—Schottky defect [111]. Such point defects play an important role in the treatment of diffusion and electrical conductivities in solids and the solubility of a salt in the host lattice of another or different valence type [112]. Point defects have a thermodynamic basis for their existence in terms of the energy and entropy of their formation, the situation is similar to the formation of isolated holes and erratic atoms on a surface. Dislocations, on the other hand, may be viewed as an organized concentration of point defects they are lattice defects and play an important role in the mechanism of the plastic deformation of solids. Lattice defects or dislocations are not thermodynamic in the sense of the point defects their formation is intimately connected with the mechanism of nucleation and crystal growth (see Section IX-4), and they constitute an important source of surface imperfection. 

Phenols hold an important place among organic pollutants, which need to be constantly monitored in waters and in places of militai y activities. Sampling of phenol matrix is conducted with solid face extragents (SPE) with further HPLC or GC analysis. Application of the known SPE usually is ineffective as it doesn t give the possibility to provide full extraction of the analyt (microcontents) in the matrix media. Therefore SPE application needs further progress in their selectivity.
