Spectroscopic and Magnetic Studies of Two Electrically Conducting Charge Transfer Compounds of 7,7,8,8-Tetracyanoquinodimethanide with Cationic Copper Chelates.
Abstract
In the initial work on charge transfer compounds of 7,7,8,8,-tetracyanoquinodimethanides, several compounds with copper chelates that had relatively high electrical conductivities were reported. One of the advantage of using copper(II) chelates as acceptors in charge transfer compounds with TCNQ- would appear to be the high probability of forming stacked TNCQ- segregated chains in preference to mixed CuL2-TCNQ stacked chains. The cationic copper chelate-TCNQ charge transfer compounds have unusual properties and have continued to attract attention. This significant finding has stimulated additional studies on TCNQ salts with copper chelates since an understanding of electron-transport properties may lead to the production of a variety of new metal-like materials. Results of our studies of the electronic structural properties of the compounds (CuL2)(TCNQ)2 (L = ethylenediamine or 1.10-phenanthroline) are reported in this article.
