“…In fact, we observed excellent properties (mobilities, threshold voltages, on͞off ratios, etc.) in the laminated transistors with every organic semiconductor that we tested: solution-cast regioregular poly(3-hexylthiophene) (p-type) (21) and evaporated films of pentacene (p-type) (22), ␣-sexithiophene (p-type) (23), dihexyl pentathiophene (p-type) (24), copper phthalocyanine (p-type) (25), copper hexadecafluorophthalocyanine (F 16 CuPc, n-type) (26), and several different oligofluorenes (27). In all cases the electrical properties of the laminated transistors are similar to those observed in top contact devices that used shadow mask Au electrodes deposited directly on the semiconductors.…”

Soft, conformable electrical contacts provide efficient, noninvasive probes for the transport properties of chemically and mechanically fragile, ultrathin organic semiconducting films. When combined with high-resolution printing and lamination techniques, these soft contacts also form the basis of a powerful technique for fabricating flexible plastic circuits. In this approach, a thin elastomeric film on a plastic substrate supports the electrodes and interconnections; laminating this substrate against another plastic substrate that supports the gate, dielectric and semiconductor levels establishes effective electrical contacts and completes the circuits. In addition to eliminating many of the problems associated with traditional layer-by-layer fabrication strategies, this lamination scheme possesses other attractive features: the transistors and circuit elements are naturally and efficiently encapsulated, and the active organic semiconductor layer is placed near the neutral mechanical plane. We demonstrate the features of soft, laminated contacts by fabricating large arrays of high-performance thin film transistors on plastic substrates by using a wide variety of organic semiconductors.

“…28 Recently, several groups have reported significant enhancements of the stability of OTFTs under ambient conditions with semiconducting small molecules, [29][30][31][32][33] oligomers, 22,24,[34][35][36][37][38][39] and polymers. Recently, our group reported anthracene main core with dialkoxynaphthalene end-capper had good oxidation stability and exhibited a field-effect performance with a mobility of 0.64 cm 2 /V·s, a subthreshold slope of 0.8 V and an on/off ratio of 7.5 × 10…”

“…A large number of oligomers have demonstrated interesting performances in OTFTs, such as fluorene, acenes and carbazole derivatives. [18][19][20][21] The synthesis of new π-conjugated units that could be incorporated in oligomeric structures could be desirable for significant optimization of OTFT performances and for a better understanding of the structure-property relationship.…”

The new organic semiconductors which are composed of divinylbenzene core unit and alkoxynaphthalene on both sides, 1,4-bis-2-(6-octyloxy)naphthalen-2-ylvinylbenzene (BONVB), 1,4-bis-2-(6-decyloxy)naphthalen-2-ylvinylbenzene (BDNVB) and 1,4-bis-2-(6-dodecyloxy)naphthalen-2-ylvinylbenzene (BDDNVB) were synthesized by Wittig reaction. The structures of obtained BONVB, BDNVB and BDDNVB were confirmed by FT-IR and mass spectroscopy. UV-absorption of thin film showed H-aggregates and J-aggregates due to closely packed structure between adjacent molecules. The characterization of vacuum-evaporated films by Xray diffraction (XRD) and atomic force microscopy (AFM) showed that the chain length of alkoxy group affects the crystallinity and morphology. BONVB with octyloxy group showed the mobility of 0.011 cm 2 /V·s, on/off ratio of 1.31 × 10 5, and a subthreshold slope of 0.93 V.

“…Excited states of thiophene attracted particular attention as this molecule constitutes the smallest building block of oligo and polythiophenes-materials extensively used in organic electronics [16][17][18][19][20]. In consequence, the energetics and electronic structure of thiophene are quite firmly established.…”
