In-plane X-ray diffraction and polarized NEXAFS spectroscopic studies on the organized molecular films of fluorinated amphiphiles with vinyl esters and their comb-polymers

Layer structures and the molecular packing in the two-dimensional lattice were studied by using the in-plane X-ray diffractions in addition to the conventional small-angle XRD, and the polarized near-edge X-ray absorption fine structure (NEXAFS) spectra for the multilayers of fluorinated amphiphiles with vinyl groups and their comb-polymers containing fluorocarbons as the side-chains. These molecular lattices were significantly different from the bulk crystals due to the film compression, and NEXAFS results show that the molecular arrangements of the fluorocarbon side-chains were strongly influenced by atoms at the ω-position of the fluorocarbon-chains.
