Progressive Growth

In this study, self-assembled alternating film using poly(diallyldimethylammonium chloride) (PDDAC) and meso-tetrakis(4-carboxyphenyl)porphyrin (MTCP) was prepared as a multilayer deposition on glass substrate. This preparation technique for dye deposition may provide new feasibilities to achieve the manufacture of ultrathin films for nanotechnology application. The deposition films were characterized by UV-vis spectrophotometer and Atomic Force Microscopy (AFM) analysis. The results of UV-vis spectra showed that the absorbance characteristic of the multilayer films linearly increased with an increased number of PDDAC and MTCP bilayers. AFM analysis showed the film surface was relatively uniform and the progressive growth of layers was determined.

Patterned Films

Polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS) is utilized in the characterization of a new class of polymeric materials that exhibit unique optical properties. The differential nature of PM-IRRAS, coupled with the fact that the experiment was performed on a commercially available hardware setup, makes the technique ideal for studying selectively deposited polyion multilayers on metal surfaces. The system under study was a polymeric thin film of alternating bilayers of sulfonated polystyrene/poly(diallyldimethylammonium chloride) (SPS/PDAC) fabricated by ionic multilayer assembly. Specifically, patterned self-assembled monolayers (SAMs) of (Ω-functionalized alkane thiolates were used as the molecular template. Alternating layers of polyanion and polycation were then selectively adsorbed onto specific regions of the surface to form a patterned films of thicknesses from 150 to 400 Å. The total thickness of the film was measured at 150 Å with the use of ellipsometry. Polyion conformation plays a crucial role in the selectivity of the patterned film, film surface characteristics, and ultimately, the ability of these systems to function as optical devices. The infrared spectroscopic data give insight into chemical composition and conformation and show that the molecular orientation of polyions in these polymeric multilayer structures depends on the ionic content of the initial solutions.
