WHEI, Oh Lin and BRITO NETO, José Thomé Xavier de. Complexing agents: podands, coronands and cryptands classification and nomenclature. Quím. Nova [online]. 1998, vol.21, n.5, pp. 630-634. ISSN 1678-7064. http://dx.doi.org/10.1590/S0100-40421998000500015.
The scientific and practical interest in crown ethers as complexing agents for actions as well as for anions and neutral low molecular species is undeniable. New molecules with crown ether properties are constantly synthesized and new application discovered. This paper presents classification and nomenclature of the classical oligoethers (crown ethers): monocyclic coronands; oligocyclic spherical cryptands; and acyclic podands.
Keywords : podand; pronand; cryptand.
