摘要

Polyisocyanides belong to one of the most important artificial helical polymers.The rigid-rod helical conformation makes them to exhibit wide potential applications in chiral recognition,enantioseparation,asymmetrical catalysis,and liquid crystals [1].Up to now,quite a few metal-promoted polymerization methods have been developed to synthesize polyisocyanides.Especially,it is a great challenge for synthetic chemists to synthesize polyisocyanides in living/controllable fashion that afford well-defined and high isotactic helical polymers.
