Poly(isocyanide)s prepared by diastereoselective polymerisation of two chiral monomers, which differ only in the presence of a nitro-group adjacent to the stereogenic group, exhibit long range chiral induction, but a surprising influence of a remote substituent on the conformation and stability of the secondary structure in the macromolecules.
通过非对映选择性聚合两种手性单体制备的聚(
异氰酸酯)表现出远距离手性诱导,但远距离取代基对大分子中二级结构的构象和稳定性的影响令人惊讶。
