| Sumario: | [eng] This thesis is mainly focused on studying the photophysical properties of Au(I), Ag(I), Cu(I), and Pt(II) coordinated compounds. This work can be divided into two parts: on the one hand, the compounds of the group 11 metals and, on the other hand, the Pt(II) compounds. In the case of the group 11 metals, Au(I) compounds with different chromophore groups have been synthesized. These compounds contain the pyridyl diphenylphosphane ligand in their structure. These compounds were designed to be used as supports. They allow the introduction of a second metal, which promotes the formation of metallophilic interactions. For the Pt(II) compounds, the synthesis of [N^N^N] ligands with different structural modifications has been carried out in order to modulate the electronic properties in the resulting coordination compounds. Various neutral ligands, such as pyridines and diphosphines, were used to study the effect of coordination at the fourth available position in the Pt(II) atoms. These ligands have been rationally chosen in order to rationalize the effects of these structures on the photophysical properties of the compounds, with the aim of modifying and/or generating supramolecular structures supported by non-covalent interactions. The design of the different compounds was aimed at promoting the generation of singlet oxygen in solution by forming structures containing a large number of metal atoms. The research group worked on the development of a new methodology for the detection of this specie in solution. The method used was a direct measurement method. This method was applied to most of the compounds synthesized in this work. It helped to lay the foundation for the design of molecules with higher activities as chemical photosensitizers. |
