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 2 (NHC)(=CHPh)(3‐Br‐C 5 H 4 N) 2 ], 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.
