Compound 4a reacts with RuCl3·3H2O in methanol producing [Ru(Brterpy)Cl3] (5a). The reaction of 5a with bidentate ligands, namely 2,2’-bipyridine and 1,10-phenanthroline, allows to obtain two monofunctional ruthenium (II) compounds: [Ru(Bipy)(Brterpy)Cl]Cl (7a) and [Ru(Brterpy)Cl(Phen)]Cl (7a’), respectively. The ligands and the ruthenium (II) complexes were characterized by infrared spectroscopy (IR) and mono- and bidimensional NMR spectroscopies. The metal compounds were also characterized by mass spectrometry. Furthermore, the study of the absorbance by UV-Vis and their fluorescence by the emission and excitation spectra were carried out. Finally, DNA interaction with complexes 7a and 7a’ was studied contrasting the effect with non-irradiated and irradiated samples with photoactivating wavelength light. The evidence from this study suggests that both complexes can act has photosensitizers57 p.application/pdfengcc-by-nc-nd (c) Pérez, 2021http://creativecommons.org/licenses/by-nc-nd/3.0/es/RuteniFotosensibilitzadorsTeràpia fotodinàmicaTreballs de fi de grauRutheniumPhotosensitizersPhotodynamic therapyBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
