Triphenyleneethynylene (TPE) monolayers at the solution-HOPG interface are oligomerized by the oxidation of pendant thioethers to form disulfide cross-links. The oligomerized TPE monolayer adheres strongly to HOPG. Disulfide reduction unzips the oligomers to form a monomeric TPE monolayer with pendant thiols. Subsequent oxidation and reduction treatments zip and unzip the monolayer.
在溶液-高定向热解石墨（HOPG）界面处，三亚苯乙炔（TPE）单分子层通过侧链硫醚的氧化形成二硫键交联而发生低聚。低聚的TPE单分子层与HOPG紧密粘附。二硫键还原使低聚物解开形成带有侧链硫醇的单体TPE单分子层。随后的氧化和还原处理使单分子层形成交联和解交联。
