Synthesis and Characterization Of Mono-, Di- and Tri- Ferrocenyl Based Molecular Compounds and Study Their Electronic Communication and Photovoltaic Performance

Abstract

Ferrocene system plays a vital role as a remarkable redox signaling unit in various organometallic molecules or scaffold. In the recent times, a large number of ferrocene based organometallic moieties have been synthesized for their application as chemosensor, energy storage device, multi-channel receptor, biosensor molecules etc. Molecular entities containing multiple redox centers have also been highly focused due to their various application related to electronic communication, sensors and molecular wire.
Since ferrocene can act as stable reversible redox couple and the redox potential can be tuned by of functionalization of its cyclopentadienyl ring, now a day’s ferrocene and its derivatives are being used as noble replacement of iodine/iodide redox couple in dye sensitize solar cell. Therefore, design of novel ferrocenyl assemblies with substituents at cyclopentadienyl ring have attracted considerable interest and led to the development of such derivatives. Molecular system containing more than one ferrocene unit shows interesting electron transfer processes when the metal center are no longer independent of each other and are said to be electronically coupled through suitable bridging chains. We have also been focusing our study on several ferrocene based molecules and recently reported the synthesis and application in the field of photovoltaic devices. In the view of enormous opportunity and to understand the various facets of these organometallic compounds, we carried out the synthesis and characterization of some ferrocene , diferrocene and triferrocene based organometallic compounds and studied their electrochemical and application to the photovoltaic devices.
