摘要：

Pyridone shows self-assembling properties via hydrogen bonds as can be shown by IR-spectroscopy. In this way networks are formed by intermolecular interaction of tris-(2-pyridone-5-carbonacid)-glycerol ester, each molecule containing three units of pyridone. The structure breaking effect of organic solvents leads to a reduced ordering of this material and can be observed directly by hyperchromic changes of the UV-absorbance. This process is traced by capacity measurements as the unpaired structures of pyridone possess a strong dipole moment. For this purpose the permittivity of an interdigital capacitor (IDC) coated with a thin solid film of the network-forming material is measured in an atmosphere of organic solvent vapours.
