title: Selective detection of guanosine-5'-triphosphate and iodide by fluorescent benzimidazolium-based cyclophanes.
abstract: New fluorescent benzimidazolium-based receptors selectively display the effective fluorescence quenching effect for biologically important anions, GTP and I(-), in aqueous solution of physiological pH 7.4. These affinities can be attributed to the strong ionic H-bonding along with additional interactions of fluorophore moieties with the nucleic base of GTP and I(-).
