Abstract

The project is about the development of luminescent molecules for use in sensors, light emitting materials and luminescent biological markers. Luminescent groups with emission in the region of the UV-vis will be targets for the syntheses. Within this target, molecules such as quinolines, 1,8-naphthalic anhydride, and the perylene-3,4,9,10-dianhydride tetracarboxylic dye are luminescent compounds, with high quantum yield and extremely suitable for this work. The binding of these molecules with the calixarenes will favor an improvement in the solubility of these compounds in organic solvents, facilitating their application as emitting materials. The synthesis of naphthylimides (via the connection of 1,8-naphthalic anhydride with calixarene-amine) has been previously prepared by our group and is very promising for the excellent luminescent response as an optical sensor [28]. In addition, the association of calixarenes with these emissive ligands suggests their use as luminescent probes or markers, and it is possible to detect specific biomolecular organization components, from a detailed monitoring of the living cells.
