    Abstract: 本研究以兩種具硫醚碳鏈之聯噻吩為核心,於其兩側引入氰基
    (CN),開發出兩系列醌型材料 DTDSTQ 及 TSBTQ。末端之氰基
    使 LUMO 能階更為下降(-4.2 eV),使其具有相當優異 n-type 電性及
    之 S‥S 分子間作用力,開發出 DTDST 核心,於其兩側引入氰基開
    發出兩個具不同長碳鏈之醌型 DTDSTQ-6 (1)、DTDSTQ-14 (2),同
    時並開發不具 S‥S 分子間作用力之 DTDRTQ-14 (3) 作為比較。
    實驗室之前已開發之醌型 SBT 分子溶解度不佳,故本論文中之
    第二系列開發出具四條硫醚鏈之 TSBT 核心以改善其溶解度。於核
    心兩側引入氰基開發出兩個具不同長碳鏈之醌型 TSBTQ-6 (4)、
    TSBTQ-14 (5)。
    利用 UV -vis 和 DPV 探討所開發分子的 HOMO 與 LUMO
    能階,藉 TGA 和 DSC 探討這些新開發材料之熱穩定性。並由溶
    液製程製成元件初步測試 DTDSTQ-14 (2) 具有 n-type 場效性質,載子移動率可達 0.4 cm2/Vs。;Two series of new quinoidals based on thioalkylated bithiopene
    cores, DTDST and TSBT, have been developed for organic thin film
    transistors (OTFTs).
    For the first series, 3, 4-dithioalkylated thiophene was end capped
    with thiophene to give DTDST core. Via the reaction of the latter with
    dicyanomethane, tetradecylthio and hexylthio quinoidals, DTDSTQ-6 (1)
    and DTDSTQ-14 (2) were developed. For comparison, tetradecylated
    DTDRTQ-14 (3) was prepared. Currently, thioalkylated DTDSTQ-14 (2) exhibit the highest mobility up to 0.4 cm2/Vs. In contrast, non-thio
    alkylated DTDRTQ-14 (3) exhibit lower mobility of 0.2 cm2/Vs. Perhaps
    due to extensively intra- and inter- S…S molecular interaction, the former
    with better conjugation, led to better molecular packing, and therefore
    demonstrated higher performance.
    For the second series, four thioalkylated bithiophenyl core, TSBT,
    was prepared to improve the solubility of quinoidals. Tetradecylthio and
    hexylthio quinoidals, TSBTQ-6 (4) and TSBTQ-14 (5) were developed.
    Currently, TSBTQ-6 (4) exhibit mobility approach to 0.1 cm2/Vs.
    All these new quinoidals exhibit pretty low LUMO (< -4.2 eV) and thus are potential air stable n-type materials.
