摘要
Abstract Rapid access to sequence‐controlled multi‐block copolymers (multi‐BCPs) remains as a challenging task in the polymer synthesis. Here we employ a Lewis pair (LP) composed of organophosphorus superbase and bulky organoaluminum to effectively copolymerize the mixture of methacrylate, cyclic acrylate, and two acrylates, into well‐defined di‐, tri‐, tetra‐ and even a hepta‐BCP in one‐pot one‐step manner. The combined livingness, dual‐initiation and CSC feature of Lewis pair polymerization enable us to achieve not only a trihexaconta‐BCP with the highest record in 8 steps by using four‐component monomer mixture as building blocks, but also the arbitrarily‐regulated monomer sequence in multi‐BCP, simply by changing the composition and adding order of the monomer mixtures, thus demonstrating the powerful capability of our strategy in improving the efficiency and enriching the composition of multi‐BCP synthesis.
