以碘酸盐为氧化剂，通过氧化－迈克尔加成反应，由邻苯二酚和4,4'-亚甲基 苯胺合成了一种新的功能聚合物，芳香胺－邻醌聚合物。这种聚合物表面由分布均 匀的纳料颗粒和孔穴构成。由于这种聚合物分子含有疏水骨架、羰基和胺基的有序 分布，以及独特的纳料微观颗粒和孔穴结构，使其成为吸附法固定化酶的良好载 体。

Using sodium iodate as an oxidizing agent, a novel arylmaine-o- quinone polymer was synthesized from 1,2-dihydroxybenzene and 4,4'- methylene dianiline by an oxidation-Michael addition. The polymer surface was constructed by uniform nanoparticles and nanoholes (about 50 nm). Owing to its aromatic backbone, amino and carbonyl groups, and its characteristic in nano-size surface structure, the polymer can be used as an ideal support for immobilized enzymes by absorption.
