摘要: Abstract With seven anthraquinone derivatives containing one or two stearylamino groups at different positions, orientation of the chromophore in built-up multilayers has been investigated by angular dependence polarized infrared spectra. The were prepared horizontal lifting method and spectra measured as functions angles for film samples inclined variously against incident beam also rotated with respect to plane polarization. In results, it found that nuclei depends markedly on numbers relative positions long substituents, accordance previous conclusion from pressure—area characteristics monolayers thickness. It should be noted some cases chromophores alkyl chains have a tendency orient depending not only vertical direction water surface but monolayer compression two-dimensional plane, other words, these exhibit double-axial films. well-defined seem useful study electronic dye aggregates.
