Self-assembly multi-layer of diazonium resin and its coupling reaction with J-acid and H-acid

Self-assembled alternating fabrication film using the diazonium resin and coupling compound was prepared as a multi-layer deposition on the glass slide. Besides, the diazo coupling reaction proceeded at the same time to form nano-scale azo dye layer. The corresponding results of multi-layer and diazo coupling reaction were characterized by UV–vis absorbance measurements. The growth of multi-layer formed by the sequential adsorption and coupling reaction of the diazonium resin and coupling compound was determined.
