Pyrrole-based metallo-macrocycles and cryptands

Author affiliations


The synthesis of dithiocarbamate ligands based on a pyrrole framework is reported. These ligands self-assemble with zinc(II), nickel(II) and copper(II) to afford neutral, dinuclear metallomacrocycles and trinuclear metallocryptands. The assembled metallo compounds have been characterised by a range of techniques, including 1H NMR, UV-vis spectroscopy, elemental analysis, mass spectrometry and X-ray crystallography. Some preliminary anion binding studies have also been conducted, using electronic spectroscopy and electrochemistry. The nickel macrocycles showed some affinity for acetate, whereas the copper cryptand showed affinity for benzoate anions. The copper cryptand also exhibited a significant electrochemical response to a range of anions.
