Abstract

We synthesised, purified and structurally confirmed three thiophene based oligomers with appreciable field effect transistor properties. The compounds present thermotropic behaviour. In order to understand the influence of liquid crystalline properties on the FET performances, differential scaning calorimetry, polarized light microscopy and thermogravimetrical analyses were performed..
