Abstract

The work described in this thesis concentrates on chemically
modified heterocyclic conducting polymers based upon pyrrole, thiophene
and indole monomers with -particular emphasis placed upon carboxylic
acid substituents. A brief description of the electrochemistry of
chemically modified poly(pyrroles) is given with an explanation of the
problems associated with the chemical modifications.
A reasonable understanding of the properties of chemically modified
poly(thiophenes) has been achieved. In particular the properties of
poly(3-thiopheneacetic acid) have been characterised in both aqueous and
nonaqueous solution using standard electrochemical techniques in
conjunction with reflectance FFIR studies.
Finally the understanding of poly(indole) and poly(5-carboxyindole)
electrochemistry has been greatly improved especially with regards to the
chemical structure of each polymer, which was elucidated from several
reflectance FTIR studies. The characterisation of the electrochemical
growth and the aqueous electrochemistry of poly(5-carboxyindole) are the
areas in which the greatest advances have been made. The techniques of
reflectance FTIR spectroscopy, UV/vis spectroscopy and impedance
spectroscopy have aided the study of poly(5-carboxyindole) immensely.
More studies need to be performed before a fuller understanding of
these polymeric systems is achieved and the final chapter gives
suggestions for further work which will add to the information given in
this thesis.
