摘要通过Cu（0）原子转移自由基聚合将聚4-乙烯基吡啶（P4 VP）刷接枝到基底上，并通过1-芘丁酸（PBA）溶液浸渍基底，将PBA与P4 VP通过氢键作用引入到刷中。在浸没后对衬底进行的荧光测量显示，PBA单元甚至在用二氯甲烷冲洗衬底后也形成准分子，这证实了P4 VP刷中的吡啶基与PBA的羧基之间形成氢键。
Abstract Poly(4-vinylpyridine) (P4VP) brushes were grafted onto a substrate via Cu(0)-mediated atom transfer radical polymerization and 1-pyrenebutyric acid (PBA) was incorporated into the brushes through hydrogen bonding interactions with P4VP by immersing the resulting substrate in PBA solution. Fluorescence measurements performed on the substrate after immersion showed that PBA units formed excimers even after the substrate was rinsed with dichloromethane, which confirms the formation of hydrogen bonds between pyridyl groups in the P4VP brushes and carboxyl groups of PBAs.
