A series of mixed W-substituted alkylpyrrole/thiophene monomers have been s
ynthesised. Several monomers could be electropolymerised to the correspondi
ng polymers. Redox behaviour, spectroscopic and conductivity measurements a
re reported. Several electroactive films are stable in the dedoped and dope
d states with conductivity as high as 10 S cm(-1). (C) 1999 Elsevier Scienc
