The investigation provides the complex approach for optical properties study of the cobalt octaephylporphyrin. The complex shows the magnetic moment of the central ions. The strength and sign of anisotropy and optical transparency within the visible range can be changed by variation of an environment of the central metal atom (the ligand field) or its replacement. As a result, these materials can be used as stable qubits and nanoelements for spintronics and quantum computing. It is well-known that devices for spintronics and quantum computing require materials with femtosecond time resolution. The insights into the relations between geometry structure and optical and magnetic properties allow to design the tailor-made materials. In this work, we have investigated the optical properties of the cobalt octaephylporphyrin. We have calculated the theoretical spectra of the extinction coefficient, refraction index, and absorption index. These spectra provide us the additional information about optical transitions within the visible range. The design of the stable nanoelements with femtosecond time resolution is hardly-probable without understanding the nature of processes.
