- Abstract
We investigate here the derivatization of pyrolyzed photoresist film (PPF) surface by anodic oxidations of amino-containing linkers in aqueous medium. As an example of application, nitrogen macrocycles are then covalently immobilized by chemical reactions with the modified surface. The surface coverage is estimated by X-ray photoelectron spectroscopic analyses and cyclic voltammetry using redox probes, and the thickness of the film is measured by atomic force microscopy from scratching experiments. The surface coverage increases when two successive grafting processes are carried out and stops after the third electrolysis. The influence of the electrolyte medium on the thickness of the film is also highlighted.
