Abstract: Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) has been successfully applied to quantifying analysis on layer-by-layer assembled macromolecular films containing diazo-resins. From the changes of -CH2-peaks,uniform adsorption of each single layer of macromolecules has been identified. We calculated the ratio of the decomposited -N≡N+ groups which form covalent bond to all -N≡N+ groups from the characteristic -N≡N+ absorption peaks. The results have provided direct and detailed information on the assembling process.
