Abstract
Synthesis, Characterization, and solution-processable organic field-effect transistor response of soluble low-dimensional two arylacetylene compounds, was reported. The compound was obtained in 90% yields by Pd/Cu catalyzed Sonogashira coupling bis(bromothienyl)-benzothiadiazole with 3,4-(bishexyloxy)- ethynylbenzene. The results show that the solid state spectra of both the compounds are red-shifted relative to the solution spectra, while a better degree of molecular π-conjugation in the solid state of J-aggregates is found. Semiconductors of both the compounds exhibit hole mobilities of approximately 0.07 cm 2 V -1 s -1 and 0.05 cm 2 V -1 s -1. The X-ray diffraction plots confirm the high crystallinity of both the compound films resulting in optimum TFT performance.
