Síntesis y caracterización de materiales moleculares de ftalocianinas metálicas en el módulo electroquímico del microscopio de fuerza atómica

Recently, molecular materials have been developed because of their electrical properties which give conductor, semiconductor, or super-conductor behavior. This study is focused on the Molecular Materials preparation by means of two different electrosynthesis techniques: electrocrystallization in conventional cells, and electrosynthesis in the electrochemical module of an Atomic Force Microscope (AFM). The latter represents an alternative method in which is possible to monitor and observe the new material as it is synthesized. Moreover, this second method presents huge advantages concerning cyclic voltammetry studies, time of electrosynthesis and preparation of the Molecular Material films for their later characterization and electrical properties evaluation. From Lead (II) phthalocyanine and 1,8 dihidroxianthraquinone compounds, new materials were synthesized by both methods. The characterization of the materials was accomplished using several analysis techniques such as IR, UV-Vis, SEM and EDS Spectroscopy. Finally, electrical conductivity was evaluated, suggesting that the materials can be classified as semiconductor molecular materials.
