Selective carriers of norepinephrine and ammonium ions: ionophoric properties and molecular modelling studies of diester crown compounds containing a 1,3-bis(1H-pyrazol-1-yl)propane unit.
Ionophoric properties of dipyrazolic crowns and podands containing a 1,3-bis(1H-pyrazol-1-yl)propane unit in their structure are described. They show selectivity of ammonium vs alkali cations and interesting norepinephrine transport rates. A molecular modelling study has been used to elucidate the superstructures of the crown and ammonium cation complexes.
