摘要：

The poly(methacrylic acids) carrying a thiol group at one terminus (PMAA-SH) or both terminuses (HS-PMAA-SH) of the polymer chain were newly synthesized. They were spontaneously adsorbed on a gold electrode and formed "polymer monolayers." Steady-state adsorption was reached after 3-5 h. The conformational transition of polymer monolayers caused by varying pH could be electrochemically detected by use of Fe(CN)64- as an electroactive species. As a result, more marked conformational changes were observed in the PMAA-SH monolayer than in the HS-PMAA-SH monolayer. © 1992.
