General description
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.
Application
Cyclen is an azamocrocycle, which can be used in the development of fluorescent nanosensors for the detection of metal ions.
