The preparation of a terthiophene system is reported, the monomer is linked
to a strongly electron-withdrawing fluorene unit via a conjugated heterocy
clic bridge and readily polymerises under electrochemical conditions: to gi
ve: the corresponding poly(thiophene). Keywords: Poly(thiophene) and deriva
tives; heterocycle synthesis; electrochemical polymerisation; special-purpo
se functionalised conjugated polymers; photoconductivity.
