Cover Story: Two novel chiral ligands, ((–)-HL1 and (–)-HL2), bearing a carboxylic acid pendant arm, were synthetized and fully characterized. The complexation behavior of these ligands toward lanthanide ions was investigated through various spectroscopic methods. A complexation trend could be deduced based on the size of the chelate cycle that these ligands can form: increasing the chelate cycle from 7 to 8 lowers the association constant. The binding is also weaker compared to the parent, previously reported ligand (+)-HL0, which forms a 6-member chelate cycle and a stable, trinuclear architecture. Hence, relatively small structural modifications of the ligand can fundamentally change the output of the self-assembly processes. View this paper
