Original Abstract

This work presents the synthesis of novel nitrated thiophene trimer and polymer. The prepared materials exhibit good thermal and chemical stability. In comparison with unsubstituted terthiophene, the substitution of an alkyl chain and chromophoric nitro groups caused the appearance of multiple absorption bands, likely due to the presence of different conformations. The experimental HOMO and LUMO levels were −6.14 eV (−3.23 eV) and −5.99 eV (−3.55 eV) for the trimer and polymer, respectively. The experimental properties were interpreted using the theoretical predictions performed for model 17 unsubstituted and 14 substituted model thiophene-aromatic ring-thiophene trimers, as well as oligothiophenes. Comparing with the expensive fluorinated derivatives, the nitrated oligothiophenes can represent a synthetically cheaper alternative material with specific electronic structure useable in construction of n-type organic semiconductors.
