Research in the area of luminescent lanthanide complexes is in constant growth, thanks to its applications in various fields such as sensors, light emitting devices, etc. Due to the extremely low light absorption of lanthanides it is essential to find ligands that allow both metal complexation and its sensitization, and which in turn can be suitably functionalized to be used in the desired applications. It is known that MCRs are an effective synthetic strategy in the construction of compound libraries, and in this sense the Ugi MCR can be used for simultaneous introduction of several coordinating groups and/or chromophores into a selected scaffold, and would thus be an extraordinary methodology for the synthesis of this kind of complexes. One structure around which we can build a unique architecture in this area is the Tröger?s base, its "V" shape allows placing different functional groups, with remote connectivity but close in space In summary, in this first stage of labor we synthesized and characterized a new ligand capable of forming complexes with Tb and Eu using an Ugi MCR.
