Surface molecular orientation of poly(2-vinylnaphalene) thin films: ARUPS and NEXAFS studies

The molecular orientation at the surfaces of poly(2-vinylnaphthalene) thin films was studied by angle-resolved ultraviolet photoelectron spectroscopy (ARUPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. The NEXAFS study showed that pendant naphthalene groups are oriented with...

Description
Summary:The molecular orientation at the surfaces of poly(2-vinylnaphthalene) thin films was studied by angle-resolved ultraviolet photoelectron spectroscopy (ARUPS) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. The NEXAFS study showed that pendant naphthalene groups are oriented with a tilt angle ( β) of 57°, while the ARUPS study gave information on the tilt-angle distribution as well as the mean value (∼58°) of β. The mean value of β determined by ARUPS agrees well with that found in the NEXAFS study.
