Abstract:

This research program was devoted to the synthesis and characterization of new transition metal compounds which had the potential of high electrical conductivities. Since band formation and electrical conductivity is enhanced by strong intermolecular interactions fully and partially oxidized metallomacrocyclic complexes were synthesized and characterized. Electrochemical methods were developed for crystal growth to overcome solubility problems which led to mixed phase products in earlier studies. These principles were extended to lanthanide complexes of phthalocyanine HPcLaPc Pc phthalocyanine, La lanthanide. These sandwich compounds contain an acidic proton which is thought to serve as a bridge between successive PcLadPc units. In some cases the phthalocyanine ring has an unpaired electron in its pi system. In this manner, strong intertechniques led to the preparation of many new compounds. A series of cationic copper complex-TCNQ charge transfer complexes, some of which exhibit high electrical conductivities, has been prepared and characterized. Other members of the series are currently under study. Hemiporphyrazine and other chain compounds with high electrical conductivities were studied, along with a series of organometallic charge transfer compounds with TCNQ.
