Inorganic compound HAuCl4, which can form a complex with pyridine, is introduced into a poly(styrene-block-2-vinylpyridine) (PS-b-P2VP) block copolymer/poly(methyl methacrylate) (PMMA) homopolymer mixture. The orientation of the cylindrical microdomains formed by the P2VP block, PMMA, and HAuCl4 normal to the substrate surface can be generated via cooperative self-assembly of the mixture. Selective removal of the homopolymer can lead to porous nanostructures containing metal components in P2VP domains, which have a novel photoluminescence property.
可与吡啶形成络合物的无机化合物四氯合金酸（HAuCl4）被引入到聚（苯乙烯-嵌段-2-乙烯基吡啶）（PS-b-P2VP）嵌段共聚物/聚甲基丙烯酸甲酯（PMMA）均聚物混合物中。通过该混合物的协同自组装，可以生成由P2VP嵌段、PMMA和HAuCl4形成的垂直于基底表面的圆柱形微区的取向。均聚物的选择性去除可导致在P2VP域中含有金属成分的多孔纳米结构，其具有新颖的光致发光特性。
