Abstract:	為了證實硫與硫之間的吸引力，開發出3個短碳鏈BST系列的分子，diTT-BST (1)、DBT-BST (2) 及DDTT-BST (3)，成功得到diTT-BST (1)的晶體結構，證實了硫與硫之間存在著相互的吸引力，增加分子的平面性。本研究並延續實驗室之可溶性硫醚?吩衍生物，延伸共軛結構，開發出DT-DSTTT(4)、DbT-DSTTT (5)、DBTT-DSTTT (6)、DDTT-DSTTT (7)，及N-type材料DFP-DSTTT (8)、DFPT-DSTTT (9)、DFPTT-DSTT (10)，並將DSTTT的結構反轉，得到DFP-DTBST (11)，已合成出的分子分別利用 UV-vis、DPV 和 TGA 及 DSC 探討分子的 HOMO 和 LUMO ，以及分子的熱穩定性。 Three thiophene-enriched BST compounds, diTT-BST (1), DBT-BST (2), and DDTT-BST (3) have have been designed and synthesized for organic thin film transistors (OTFTs). The Crystal structure of diTT-BST (1) shows that the S-S interaction between the thiophene-S and alkyl chain-S are the dominant stabilizing force governing the packing of the molecules. These materials were designed to study the effect of extended conjugation on the photochemical, photophysical, and electrochemical properties. All of these new semiconductor materials exhibit good stability under thermal conditions and their electron mobility analysis is now in under progress.
