具有侧臂上有三个吡啶和一个三唑的十八齿环的Ca（2+）配合物介导了从外部手性源到配位吡啶和香豆素部分的两点手性转移。通过配位外手性阴离子的酯化偶联，反复写入、删除和重写诱导手性信息。
A Ca(2+) complex with octadentate cyclen having three pyridines and one triazole on its sidearms mediated two-point chirality transfer from an external chiral source to the coordinating pyridine and coumarin moieties. The induced chirality information was repeatedly written, deleted, and rewritten by coupling with esterification of the coordinating external chiral anion.
