The involvement of halogen bonding in conducting molecular materials is essentially based on the use of halogenated TTFs in electrocrystallization experiments with counter ions of Lewis base character prone to act as halogen bond acceptors. This concept was first successfully introduced by Imakubo... 

Since the discovery of the first organic semiconductor perylene-bromine complex in 1954 [1], a large number of molecular conductors, including more than 100 molecular superconductors, have been prepared. Conducting molecular materials are characterized by the following features ...

If the temperature of a water mass is altered after having been isolated from the sea surfece, deviations from saturation can result. Such alterations are a consequence of heat transport via either conduction (molecular diffusion of heat) or turbulent mixing of adjacent water masses. In the case of the former, hydrothermal systems are important subsurface heat sources. If two water masses of different temperature imdergo turbulent mixing, the temperature of the admixture will differ from that of the source waters.

When representing rates of transfer of heat, mass, and momentum by eddy activity, the concepts of eddy thermal conductivity, eddy diffusivity, and eddy viscosity are sometimes useful. Extending the concepts of heat conduction, molecular diffusion, and molecular viscosity to include the transfer mechanisms by eddy activity, one can use Equations 2.13-2.15, which correspond to Equations 2.2,2.3, and 2.5, respectively. 

Numerous investigations concerning electrophilic substitution of indolizines have been conducted. Molecular orbital calculations of varying degrees of sophistication showed that the most reactive site is position 3 followed by position 1 of the nucleus.

Partial oxidation of some nickel(II) complexes with phthalocyanine and porphyrins gives rise to conducting molecular solids of the type Ni(pc)Ij (x = 0-3) and Ni(porphyrin)I (Table 110).2884,2891 2895,2909 The oxidation of Ni(pc)Ix is reversible and the iodine can be completely removed from the compound by heating it in vacuo. The aforementioned compounds may be...

A few years after these events, a review article by McCleverty4 in 1968 provided (in over 170 pages) the first thorough overview of this field. This review contains a multitude of details which still merits its mention as a valuable source of information on this class of compounds. Several other reviews dealing with different aspects of dithiolene chemistry have appeared in the meantime.5"11 The field has expanded in different directions, spurred by the synthesis of several structurally unique compounds and of materials of particular use in quite diverse areas such as highly conducting molecular crystals and as infrared dyes for various applications. Dithiolenes thus represent a class of materials which are not only of significance on their own, but which also find some applications in which their unique electronic properties can be employed. 

In the context of synthesizing highly conductive molecular solids, Sandman et a/.84 have prepared the Bu4N salt of the planar benzenediselenole Ni complex anion (61).

Anomalous properties—thermal expansivity and thermal conductivity. Molecular simulation has been integral in evaluating physical behaviors of hydrate compared with ice, specifically a larger thermal expansivity (Tse, et al., 1987 Tanaka, et al., 1997) and a glasslike thermal conductivity (Tse, et al., 1983 1984 Inoue, et al., 1996). These properties have been explained by the coupling between the water and the guest molecules. 

Modification and functionalisation of natural polyenes, the carotenoids, is an efficient way for the molecular engineering of polyenic chains. Terminal bis-pyridinium carotenoids, termed caroviologens, represent an approach to electron conducting molecular wires (5). Fitting polyconjugated chains with an electron donor group on one end and an electron acceptor on the other end yields push-pull systems of type 1 that may be considered as polarized, unidirectional (oriented) molecular wires and also possess marked NLO properties.
