General description

1,4,8,11-Tetraazacyclotetradecane is an azamacrocycle that forms more stable metal complexes as compared to open chain ligands.

Application

1,4,8,11-Tetraazacyclotetradecane (cyclam) can be used as a ligand in the synthesis of:
  • Cyanide-bridged FeIII-CuII complexes.
  • Zinc fenamate complexes [Zn(cyclam)(fen)2] possessing antimicrobial properties, fen = fenamic acid.
  • Zn(II) complexes with flufenamic acid (flu), [Zn(cyclam)(flu)2].
  • Polyoxometalate-metal organic extended framework, for example [{Cu(cyclam)}3(W7O24)].15.5.H2O.

A series of reducible polycationic copper chelators (RPCs) based on 1,4,8,11-tetraazacyclotetradecane (cyclam) were synthesized by Michael addition. Molecular weight of the polycations was controlled by reaction stoichiometry and reaction conditions, resulting in polymers with molecular weights ranging from 4400 to
