The lanthanide-based visible and NIR luminescence emission attracts a considerable interest in the field of lighting, light emitting diodes, light converters, optical fibres for telecommunication, logic gates, barcoded materials, labels for biomedical analysis, chiral recognition or sensors. In theses fields, the creation complexes, edifices or devices based on lanthanide (III) is obtained with the association of metals and organic chromophores. Application of the supramolecular chemistry to coordination chemistry is relatively recent and of a great interest for supramolecular architectures but has lagged behind that of other systems due to the difficulty in the control of the coordination environment of the ions.

In this project the synthetic methods for the incorporation of different lanthanide ions in monometallic complexes, polymetallic assembly, multidimensional coordination polymers and multicolour platforms will be developed. The objective is to provide systems with high luminescent quantum yield and sensitization of the lanthanide ions with excitation a low energy (350-450 nm). Nano-sized materials will be developed from these assemblies. This project involves organic synthesis of new ligands and small organic molecules, the synthesis of nanoparticles and the study of their coordination chemistry lanthanide ions using different spectroscopic techniques
