title: Selective complex formation of some chromogenic calix[4]arene derivatives detected by Fourier transform infrared spectroscopy 2. Solid experiments.
abstract: Two chromogenic calix[4]arene derivatives having identical coordination sphere (consisting of ester groups) but different chromogenic units (pyridinium type and dinitro-phenyl type) were the subject of structural studies with sodium(I) and thallium(I) ions in solid state, both as bulk and surface complexes. Their diffuse reflectance infrared Fourier transform (DRIFTS) spectra were recorded and the characteristic changes of the vibrational spectra due to complex formation were analysed based on curve fitting.
