The following research studies the non-covalent pi-stacking adsorption of polyaromatic cobalt(II) transition metal complexes on glassy carbon electrode surfaces. Synthesis of the ligands shown in the figure and of the complexes Co(tpy~nap)₂²⁺, Co(tpy~py)₂²⁺, Co(bpy~nap)₃²⁺, and Co(bpy~py)₃²⁺ was completed using simple organic and inorganic chemistry. Cyclic voltammetry techniques were used to examine the kinetics and thermodynamics of the adsorption of these complexes on glassy carbon surfaces. All adsorption was found to be spontaneous and to be described by an activation control kinetic model. Surface coverage data from many experiments at varying concentrations were fit to a Langmuir isotherm, and the saturation coverage and free energy of adsorption was calculated for each complex. Significant differences, both in saturation coverage and in the free energy of adsorption were observed among the complexes studied. This result demonstrates how deliberate synthetic modifications can be used to control the process of surface functionalization.
