The laser ionization mass spectrometry technique has been used for the study of FeCl3-doped poly(phenylacetylene) (FeCl3-PPA). Assessment of the ionic fragments has been exploited by comparison of the spectra of FeCl3-PPA with those of reference compounds. Evidence of carbon clusters bonded to iron or to the FeCl moiety is reported; interaction of the chain C=C double bonds with iron leads to stable complexes where the allenic or acetylenic chains can be considered as macro ligands. The negative-ion patterns give evidence of the charge-transfer reaction also occurring between FeCl3 and PPA.

Abstract
The laser ionization mass spectrometry technique has been used for the study of FeCl3-doped poly(phenylacetylene) (FeCl3-PPA). Assessment of the ionic fragments has been exploited by comparison of the spectra of FeCl3-PPA with those of reference compounds. Evidence of carbon clusters bonded to iron or to the FeCl moiety is reported; interaction of the chain C=C double bonds with iron leads to stable complexes where the allenic or acetylenic chains can be considered as macro ligands. The negative-ion patterns give evidence of the charge-transfer reaction also occurring between FeCl3 and PPA.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
