Multi-block polymers are highly desirable for their addressable functions that are both unique and complementary among the blocks. With metal-containing polymers, the goal is even more challenging insofar as the metal properties may considerably extend the materials functions to sensing, catalysis, interaction with metal nanoparticles, and electro- or photochrome switching. Ring-opening metathesis polymerization (ROMP) has become available for the formation of living polymers using highly efficient initiators such as the 3rd generation Grubbs catalyst [RuCl (NHC)(=CHPh)(3-Br-C H N) ], 1. Among the 24 possibilities to introduce 4 blocks of metallopolymers into a tetrablock metallocopolymer by ROMP using the catalyst 1, two viable pathways are disclosed. The synthesis, characterization, electrochemistry, electron-transfer chemistry, and remarkable electrochromic properties of these new nanomaterials are presented.
多嵌段聚合物因其各嵌段之间独特且互补的可寻址功能而备受青睐。对于含金属聚合物而言，由于金属性质可能会极大地扩展材料的功能，如用于传感、催化、与金属纳米粒子相互作用以及电致或光致变色开关，因此目标更加具有挑战性。开环复分解聚合（ROMP）已可用于使用高效引发剂（如第三代 Grubbs 催化剂[RuCl（NHC）（=CHPh）（3-Br-C H N）]）形成活性聚合物。 1 、在使用催化剂 1 通过 ROMP 将 4 个嵌段的金属聚合物引入四嵌段金属聚合物中这 24 种可能性中，揭示了两种可行的途径。介绍了这些新型纳米材料的合成、表征、电化学、电子转移化学和显著的电致变色性质。
