Organic field-effect transistors were fabricated using solution-processed films, and only one derivative, bis-tricyanovinyl-DSP, exhibited transistor behavior with μe reaching 8.7 × 10–4 cm2/V·s. This enhancement of the electron-transporting properties in comparison with DTP derivative is attributed to stronger LUMO–LUMO interaction due to a larger size of selenium atom, which in the case of the bis-tricyanovinyl derivative, has wave function density on the chalcogen.
