Pyrylium salts for bioimaging, sensing and solid-state emission

Résumé

The thesis entitled "Pyrylium salts for bioimaging, sensing and solid-state emission" is structured in 7 chapters that cover different aspects related to several applications of pyrylium salts. Two chapters correspond to biological applications, in which the synthesis and characterization of molecules that are used as mitochondrial probes and nitric oxide sensors is carried out. A third one introduces an analytical application, where pyrylium compounds are used for water sensing in organic solvents. And in the last one, an optic approach is proposed and the development of a family of compounds as solid-state emitters is presented. Due to its synthetic ease and good photophysical properties, it's concluded that the use of pyrilium salts could be expanded even further in the future into fields in which they have not been fully exploited, such as bioanalysis.
