Organic Thin Film Transistors based Oligothiophine Derivatives using - Dihexyl ( quarter - & sexi - ) Thiophene
نویسندگان
چکیده
End-substitution of quarterthiophene and sexithiophene with hexyl groups leads to highly soluble conjugated oligomers, -dihexylquarterthiophene (DH-4T) and -dihexylsexithiophene (DH-6T). We have characterized these oligomers for optical and electrical properties. We fabricated an organic thin film transistor (OTFT) using the above two air-stable p-type organic semiconductor materials. We obtained a stable characteristic curve. The field effect mobility, was calculated to be 3.29×10 cm/Vs for DH-6T based OTFT; while the DH-4T based OTFT had 1.88×10 cm/Vs. Keywords—Organic thin film transistor, -dihexylquarterthiophene, -dihexylsexithiophene.

A new tellurophene-based π-conjugated polymer, PDTDPPTe, was synthesized. PDTDPPTe exhibits a smaller optical band gap (E(g)(opt) = 1.25 eV) than thiophene-based PDTDPPT (E(g)(opt) = 1.30 eV). Thin-film transistors comprising PDTDPPTe displayed outstanding performance (μ(max) = 1.78 cm(2) V(-1) s(-1), I(on)/I(off) = 10(5-6)).
