We have investigated thin films of a DCBA prepolymer on Si and Al substrates. High-resolution Cls, Ols and Nls x-ray photoelectron spectra reveal some thickness-dependent features, which lead to an adsorption model for the DCBA prepolymer molecules. The adsorption of the first layer is governed by the interaction of the triazine rings with the substrate interface.
