Abstract

Novel benzodithieno[3,2-b]thiophene (BDTT) derivatives with two alkoxy-side chains were synthesized and characterized. Organic field-effect transistors (OFETs) based on these compounds were fabricated and characterized. Thin film FETs based on BDTT-4 with shortest side-chains display a high performance with a carrier mobility of up to 2.6 cm² V^-1 s^-1 and a current on/off ratio exceeding 10⁸ in N₂, which is one of the highest values for acenedi(thieno)thiophene-based OFETs so far.
