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.
含多巴胺的单体，N-3,4-二羟基苯乙基甲基丙烯酰胺（DMA）和甲基丙烯酸二甲氨基乙酯（DMAEMA），通过环境温度下单电子转移引发以及通过自由基加成断裂链转移（SET-RAFT）方法进行的可控聚合反应，成功地以良好控制的方式进行了共聚。通过一级动力学曲线、分子量之间的线性关系以及单体转化率，同时保持相对较窄的分子量分布（Mw/Mn≤1.45），证实了共聚反应的可控行为。此外，聚（N-3,4-二羟基苯乙基甲基丙烯酰胺-共-甲基丙烯酸二甲氨基乙酯）PDMA-共-PDMAEMA与无机颗粒的仿生自组装被用于通过调节预先设计好的化学组成来制备可调谐的蜂窝状多孔杂化颗粒（HPHPs）。另外，无机牺牲模板被成功地选择性蚀刻以形成多孔有机材料。
