Dopamine‐containing monomers, N ‐3,4‐dihydroxybenzenethyl methacrylamide (DMA) and dimethylaminoethyl methacrylate (DMAEMA), are successfully copolymerized in a well‐controlled manner via ambient temperature single‐electron transfer initiation and propagation through the radical addition fragmentation chain transfer (SET‐RAFT) method. The controlled behaviors of the copolymerization are confirmed by the first‐order kinetic plots, the linear relationships between molecular weights, and the monomer conversions while keeping relatively narrow molecular weight distribution ( M w / M n ≤ 1.45). Moreover, biomimetic self‐assembly of poly( N ‐3,4‐dihydroxybenzenethyl methacrylamide‐ co ‐dimethylaminoethyl methacrylate) PDMA‐ co ‐PDMAEMA and inorganic particles are employed to prepare tunable honeycomb‐like porous hybrid particles (HPHPs) by regulating the predesigned chemical composition. In addition, the inorganic sacrificial templates are successfully selective etched for the formation of porous organic materials.
