Synthesis and Characterization of Trivalent Complexes of Cr, Fe, and Co Bearing Avobenzone and Oxybenzone Ligands

Paige Blavat, Ariana Madera, Sam Whempner, and Paige Pearson

Abstract

In this study, homoleptic complexes of trivalent chromium, iron, and cobalt were prepared with two different β-diketonate ligands, avobenzone and oxybenzone. These systems are being studied for the potential to absorb light in a useful wavelength range to enhance solar cell efficiency and for their geometric isomer preference. Methods unique to each metal were necessary to obtain these targeted complexes. A variety of techniques have been employed to verify their successful isolation including IR spectroscopy, mass spectrometry, magnetic susceptibility and melting point determination.
