    Abstract: 藉由縮短 DSTTT 的碳鏈,開發出短碳鏈 DSTTTM (1),且成功得到其晶體結構,證實硫原子和硫原子之間存在著相互作用力。除此之外,延續實驗室開發的硫醚碳噻吩系列,結合實驗室所發表具有高載子移動率的核心BST 和 STT,開發出短碳鏈 DSTSTTM (2)。另一方面,利用 BST 和 DSTTT 分子,在末端引入 dicyanomethylene 基團改變分子整體共振結構,開發出 n-type 材料 TCN-BSTQ (3)、TCN-DSTTTQ (4),並將合成出的新分子利用 UV-vis、DPV探討分子的 HOMO 和 LUMO 能階,並藉由 TGA 及 DSC 探討新分子的熱穩定性。目前材料之元件正在測量中,但從氧化環原電位可預期這一系列的 n-type 材料之 OTFTs 會具有良好的空氣穩定度。;A series of new materials based on fused thiopene have been developed for organic thin film transistors (OTFTs). First, crystal structure of DSTTTM (1) core was obtained and exhibited intramolecular S-S interactions between the thiophene-S and alkyl chain-S. Secondly, by coupling BST and STT, new DSTSTTM (2) core was successfully synthesized. Finally, two new n-type quinoidal materials based on DSTTT and BST have been developed. The LUMO energy level of these two new developed materials was as low as -4.23 eV and thus are potentially air stable n-type OSCs. The OTFTs studies of these new compounds are in progress.
