Electrosíntesis de materiales moleculares de fierro y cobalto

Molecular materials are formed by the condensation and rearrangement of molecular units. Their microstructure is of special interest because they are generally formed by a regular molecular pattern that can generate preferential ways for electrical conduction, which is why they are sometimes called quasi-one-dimensional solids or low-dimensional linear chains. This work reports the synthesis and characterization of iron and cobalt molecular materials that were formed through an oxidation-reduction reaction in an electrosynthesis cell from electronic acceptor and donor species. Material characterization was made through infrared (IR) spectroscopy, scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). These materials have a structure of polymeric chains formed from the coordination of the metallic ion to the phthalocyanine with the organic compound 1,8-dihydroxyanthraquinone. The synthesized materials show large chemical and thermal stabilities which may lead to their application in thin-film technology. Their room-temperature thermal conductivity in pellet form is of the order of 1×10^-6Ω^-1cm^-1.
