Descripción general
Cyclen is a microcyclic tetramine that can be used as a ligand that forms a co-ordination linkage with the surface metal cations. It can be used as a synthetic precursor. It can be prepared by S-alkylation of dithiooxamide with an excess amount of bromoethane.
Aplicación
Cyclen is an azamocrocycle, which can be used in the development of fluorescent nanosensors for the detection of metal ions.

The design and synthesis of dinuclear-lanthanide complexes possessing triazole-based bridges, formed by using copper catalysed 1,3-cycloaddition reactions between heptadentate alkyne functionalised cyclen europium or terbium complexes and di-azides (CuAAC reactions), are described. While this click reaction worked well for the
