Paper
The self-assembly between the amidothiourea ligands1 and 2 and Tb(III) gave rise to the formation of 1 : 1 and 3 : 1 (ligand–Tb) supramolecular architectures that were shown to be luminescent in both MeOH and in water–DMSO solutions; preliminary investigations in the latter system also showed that their emission was modulated upon interacting with anions such as acetate and phosphate due to host–guest formation.
