A new emissive macrocycle ligand bearing three phenylurea groups (L 1) has been synthesized and fully characterised. Several mononuclear complexes with nitrate, perchlorate and tetrafluoroborate salts of transition and post-transition metals (Cu2+, Ni2+, Co2+, Zn2+ and Cd2+) were synthesized and characterised. For comparative purposes, the coordination ability of two nonfluorescent macrocyclic ligands (L2 and L3) containing three nitrophenylurea pendant-arms towards the same metal ions were studied. The interaction with transition and post-transition metal ions, and anions was explored in solution by UV-Vis and emission spectroscopy with ligand L1. All new compounds were characterised by microanalysis, IR, UV-Vis and fluorescence emission, FAB and ESI mass spectrometry and conductivity measurements.
