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 w ere studied by using the in-plane X-ray diffractions in addition to the con ventional small-angle XRD, and the polarized near-edge X-ray absorption fin e 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 t he molecular arrangements of the fluorocarbon sidechains were strongly infl uenced by atoms at the omega -position of the fluorocarbon-chains.
