- Solution processable symmetric 4-alkylethynylbenzene end-capped anthracene derivatives
-
New candidates composed of anthracene and 4-alkylethynylbenzene end-capped oligomers for OTFTs were synthesized under Sonogashira coupling reaction conditions. All oligomers were characterized by FT-IR, mass, UV-visible, and PL emission spectrum analyses, cyclic voltammetry (CV), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), 1H-NMR, and 13C-NMR. Investigation of their physical properties showed that the oligomers had high oxidation potential and thermal stability. Thin films of DHPEAnt and DDPEAnt were characterized by spin coating them onto Si/SiO 2 to fabricate top-contact OTFTs. The devices prepared using DHPEAnt and DDPEAnt showed hole field-effect mobilities of 4.0 × 10-3 cm2/Vs and 2.0 × 10-3 cm2/Vs, respectively, for solution-processed OTFTs.

- NOVEL ORGANIC SEMICONDUCTOR COMPOUND, AND ORGANIC THIN FILM TRANSISTOR USING THE SAME
-
The present invention relates to novel mono- molecular organic semiconductor compounds and organic thin film transistors comprising the same. The organic semiconductor compounds according to the present invention are characterized by a structure of an acene derivative substituted with acetylene groups at both ends, a structure of anthracene derivative substituted with acetylene groups, or a structure of a multi-nuclear aromatic derivative functionalized by naphthalene having an electron-donor substituent at both ends.
