Inorganic and Organometallic Materials

Inorganic materials, usually involving transition metals, and organometallics exhibit a thermochromic response over a wide range of temperatures and by a variety of mechanisms. Examples include

An important point to note is that several classes of organic, inorganic and organometallic materials which may fall in a gray area are not treated as CPs and thus excluded from this book. Specifically, these include ...

The reasons for the success of inorganic and organometallic macromolecules over the corresponding organic materials stand on the structure-property relationships existing in these polymers.

Thus, important structure/property relationships are emerging that are relevant to electronic and optical materials applications for these materials. In a different vein, side chain crystallization has resulted in the first liquid crystalline inorganic and organometallic macromolecules, viz., unusual poly(dialkoxy-phosphazenes) described by Allcock (p. 250) and Singler (p. 268). 

Finally, one additional comment concerning the nature of progress from interdisciplinary research is evident from the results reported in this Symposium Volume. Once again it is seen that most rapid progress is made when synthetic chemists collaborate with their colleagues in materials science or physics to determine properties of new inorganic and organometallic polymers. 

The development of chemistry in the last 20 years has revealed a significant shift of interest on the part of theoreticians and experimentalists [1,2]. Earlier, chemists attention was concentrated on atoms and atom-atom bonds. This strategy has been very successful in the creation of new molecules with unusual structures and with new chemical and physical properties. However, two decades ago, the primary objects of chemical studies become intermolecular interactions leading to complex molecular assemblies that exhibit unusual and often unique macro properties. This situation has dominated in all areas of modem chemical science from physical, organic, inorganic, and organometallic chemistry to material science and biochemistry, and has resulted in the formulation of new chemical disciplines supramolecular chemistry and crystal engineering. 

The oxyfluorinated polymers would be expected to react with a variety of organic, inorganic, and organometallic compounds. Derivatives of each functionalized material have been prepared with CH3OH, C2HsOH, n-BuOH, and aniline. The efficiency of the derivativization process ranged from 44 to 98%.

To conclude this article, it is hoped that the discussion of relevant issues and opportunities for chemists presented here will sufficiently stimulate the interest of the chemical community. Their active participation is vital for building our understanding of optical nonlinearities in molecular systems as well as for the development of useful nonlinear optical materials. It is the time now to search for new avenues other than conjugation effects to enhance third-order optical nonlinearities. Therefore, we should broaden the scope of molecular materials to incorporate inorganic and organometallic structures, especially those involving highly polarizable atoms.

From the viewpoint of molecular chemists, inorganic metal amides or primary amides, the derivatives of ammonia, are related to solid state chemistry. However, both inorganic and organometallic amides are mentioned in the same breath. In a world of new materials where, e.g., ceramics [16,17] and hard...
