Abstract
In two different types of experiments, polymer films on gold substrates were investigated by optical second harmonic generation (SHG). Thickness dependent ex situ measurements on Langmuir-Blodgett films of the octadecylammonium salt of polyamic acid (PACS) show a preferential orientation of the polymer molecules. In situ SHG experiments were performed to monitor the growth of polyamic acid films deposited from the gas phase. Pyromellitic dianhydride (PMDA), 4,4′-oxydianiline (ODA), and 4,4′-diaminodiphenyl disulfide (DAPS) served as monomers. Similar to the Langmuir-Blodgett films, an oriented growth is observed. The thickness dependence of the SHG signal is strongly dependent on the interfacial chemistry which is very different for the two amines used as monomers. Based on a comprehensive three layer model, the relation between the structure of the films and the SHG signal is discussed.
