Synthesis and Characterization of Naphthalene End-capped Triethylsilylethynyl Anthradithiophene for Organic Thin-Film Transistors

초록

Naphthalene end-capped triethylsilylethynyl anthradithiophene was synthesized by a Suzuki coupling reaction. The obtained compound had good solubility due to its bulky triethylsilylethynyl groups although the extended -conjugated backbone structure. The thermal stability of the new material was analyzed by thermogravimetry analysis and differential scanning calorimeter thermograms. The optical and electrochemical properties were examined. A thin film of compound was fabricated by spin-coating and exhibited p-channel organic thin film transistors (OTFTs) transport with hole mobility of 4x10(-4)cm(2)/Vs.
