Abstract

The effect of three non-nucleophilic bases (2,6-di-tert-butylpyridine (TBP), 7-methyl-1,5,7-triazabicyclo[4.4.0]-dec-5-ene (MTBD) and 1,5-diazabicyclo[4.3.0]-non-5-ene (DBN) on the polymerization of thiophene and 3-methylthiophene has been studied by spectrally following the film deposition. A clear inhibiting effect was observed with each base. The additives increased the delay time before the start of film deposition and decreased the rate of film formation. The unsucessful polymerizations resulted in the formation of a terthiophene-type compound. The inhibiting effect was attributed to the deprotonation of the intermediates in the early stages of the polymerization reaction.
