Abstract Porphyrins are complexes with a huge resonance in the research industry, which has been increasing in recent years as they are widely applied. The reason is that they are free in nature, having a very decisive role in biological activities because of its unique characteristics and properties. One of the sectors that pioneered the synthetic interest of porphyrins is renewable energy. In the present thesis, the theory on which the course of the following research is based is first analyzed. Hereinafter, the synthetic approach of the dimeric porphyrin derivatives TPP(In)-NH2-gef-NH2- TPP(In) and TPP(Sn)-NH2-gef-NH2-TPP(Sn) is of particular importance in the bridge composition between of the two molecules, as it gives particular features to the complex being synthesized. At the same time, the synthesis of the final product namely TPP(Zn)-NH2-gef-NH2-TPP(Zn) complex is explained. In addition to the synthetic approach of porphyrin derivatives, the study and characterization methods used during the experimental procedures for the determination of end products are analyzed. Visible-ultraviolet (UV-Vis), mass fluorescence (Maldi-TOF) and magnetic nuclear resonance (NMR) 1H and 13C spectra were obtained for complete description and identification at each step of the synthesis of intermediates. Finally, the synthesis and characterization of porphyrin complexes was achieved with the main aim of using them as a photosensitizer in dye sensitized solar cell (DSSC).
