| Abstract: | A series of enantiomeric 2,6‐bis(1,2,3‐triazol‐4‐yl)pyridines (btp)‐containing ligands was synthesized by a one‐pot two‐step copper‐catalyzed amine/alkyne click reaction. The EuIII‐ and TbIII‐directed self‐assembly formation of these ligands was studied in CH3CN by monitoring their various photophysical properties, including their emerging circular dichroism and circularly polarized luminescence. The global analysis of the former enabled the determination of both the stoichiometry and the stability constants of the various chiral supramolecular species in solution. |
