Spontaneous Adsorption of a Co-Phthalocyanine Ionic Derivative on HOPG. An In Situ EPR Study
Original language description
The spontaneous adsorption of [N,N',N '',N'''-tetramethyltetra-3,4-pyridino-porphyrazino-Co(II)] ([CoTmtppa](4+)) from an aqueous solution onto highly ordered pyrolytic graphite (HOPG) was followed by in situ electron paramagnetic resonance (EPR). The solution of [CoTmtppa](4+)(CH3SO4)(4)(-) exhibits no EPR signal in the temperature range from 120 to 293 K. At room temperature, on the other hand, the EPR spectra of both spontaneously adsorbed and powdered [CoTmtppa](4+) were unambiguously identified bythe spectral simulations and quantum chemical calculations. The results indicated different geometries for the powdered and adsorbed samples. The time evolution of the EPR spectrum of [CoTmtppa](4+) and that of HOPG during the adsorption made it possibleto obtain a kinetic picture of the process. Finally, the structure and the redox stability of the magnetically active [CoTmtppa](4+) molecular film on HOPG was studied by atomic force microscopy (AFM), X-ray photoelectron spectroscopy (X
