Synthesis and Characterization of Some Disubstituted Cyclopentadienyl Rhenium Complexes as Potential Candidates in Semiconductive Materials

Book excerpt: Since 2000, when the Nobel Prize in Chemistry as awarded for conductive polymer research few studies have been performed concerning the conductive capabilities of discrete organometallic compounds. For this project, organometallic compounds were formed specifically with a transition metal included in the structure. Through oxidation and reduction reactions, the variation in the electrical conductivity could allow for an analysis of whether this unique structure would allow for tunability. The goal of this research was to begin with aromatic substituted fulvenes and perform various multistep synthesis processes, utilizing thallium salt intermediates, to produce several disubstituted cyclopentadienyl rhenium complexes. In this project, different rhenium complexes were synthesized accurately and with high yield utilizing methods that were straightforward and generated replicable results. Through melting range analysis, IR spectroscopy, 13C NMR, and 1H -NMR, the identity and purity of these compounds were confirmed.
