Resum

The application of laser desorption/ionization and matrix-assisted laser desorption/ionization mass spectrometry to the study of the structure of some conducting polymers was investigated. A methodology was developed and the experimental conditions for the characterization of these polymers were established. The parameters chosen to be changed for the method optimization are the matrix material (seven different matrices were tested depending on the polymer studied) and the solvent used in the preparation of the samples. The method seems to be suitable for the study of the structure of two oxidation states of polyaniline: emeraldine and pernigraniline. The analysis of the polymers derived from m-aminophenylbenzothiazole, benzothiazole and tetrathiopentalenes was also performed. Copyright (C) 2000 John Wiley and Sons, Ltd.
