We use a Ni(II) diimine catalyst to prepare the first examples of the controlled synthesis of electron-rich/electron-deficient all-conjugated diblock copolymers. These catalysts are able to control polymerizations of both electron-rich and electron-deficient monomers, which we attribute to strong association to both monomer types. Block copolymers are prepared by controlled chain extension, and their structure is verified by gel permeation chromatography, H NMR, electrochemistry, calorimetry, and atomic force microscopy.
我们使用一种镍（II）二亚胺催化剂来制备富电子/缺电子全共轭二嵌段共聚物可控合成的首个实例。这些催化剂能够控制富电子和缺电子单体的聚合反应，我们将其归因于与这两种单体类型的强缔合作用。通过可控链增长制备嵌段共聚物，并通过凝胶渗透色谱法、核磁共振氢谱、电化学、量热法和原子力显微镜对其结构进行验证。
