Abstract:
Novel thiophene-based oligomer, 2,2 -bis(2,2 -bithiophene-5-yl)-3,3 -bithianaphthene (TX), was
designed and synthesized, and its electrochemical and spectral properties characterised. TX was readily
polymerised electrochemically to form well organized conducting homopolymer films on various
solid electrode substrates. Moreover, it was successfully used for deposition by electropolymerisation
of electrochemically active thin films of co-polymers with three different monomers of functionalised
bis(2,2 -bithienyl)methane derivatives. It appeared that TX was an effective crosslinker and 3D promoter
in these electropolymerisations involving co-monomers intrinsically showing limited aptitude for the
electropolymerisation or forming polymer films of low conductivity. This attractive TX ability stems
from combination of its (i) high conjugation efficiency in each of the two planar moieties, (ii) intrinsic
3D structure on account of the presence of the central node, and (iii) intrinsic regioselectivity in
electropolymerisation on account of the positions of the two available free -thiophene sites.
