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
通过一锅两步铜催化的胺/炔点击反应合成了一系列对映体2,6-双(1,2,3-三唑-4-基)吡啶(btp)配体。通过监测CH 3 CN的各种光物理性质,包括新兴的圆二色性和圆偏振发光,研究了这些配体的Eu III和Tb III定向自组装形成。对前者的整体分析使得能够确定溶液中各种手性超分子物种的化学计量和稳定性常数。
