第一个由非手性合成聚合物组成的人工双螺旋结构是通过聚三亚甲基亚胺盐和卟啉桥连的BisPYBOX通过PYBOX基团与聚合物中仲铵阳离子之间的氢键扭曲形成的超分子梯状结构构建的。
The first artificial double helix composed of achiral synthetic polymers have been constructed by twisting of a supramolecular ladders from poly(trimethylene imine) salts and porphyrin-bridged BisPYBOXs through hydrogen bonds between the PYBOX groups and secondary ammonium cations in the polymer.
