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 (Mw/Mn ≤ 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.
