Synthesis and TFT Properties of Fluorenyl Cored Conjugated Compound for Organic Thin Film Transistors
The 5,5′-(4,4′-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,1-phenylene))bis(2-hexylthieno[3,2-b]thiophene) FCBT (6) was synthesized by connecting the fluorenyl, thienothiophenyl and phenyl units. The compound was characterized by FT-IR, H1NMR, C13NMR
and mass spectroscopy. The compound has shown good solubility and thermal stability over 417 °C. The compound has shown hole mobility of 4.76 × 10−6 cm2/Vs. The on–off ratio and threshold voltage were 7.5 × 102 and −8.26 V
respectively.
