| dc.description.abstract | 本研究主要開發具硫醚鏈及硒醚鏈之有機薄膜電晶體?吩材料，
在硫醚鏈系列中開發出 n 型材料 TSBTQ 與 p 型材料 DDTTDSDTT
。在硒醚鏈系列中，開發出以 SeBT 為核心之多個 p 型小分
子材料。
本實驗室之前已開發具四硫醚鏈之 n 型分子 TSBTQ-6 與
TSBTQ-14，其硫醚鏈分別為 C6H13 與 C14H29，兩者元件電性分別已
具 0.10 cm2V-1s-1 和 0.14 cm2V-1s-1。本研究繼續探討硫醚碳鏈之鏈長
效應，開發出硫醚鏈為 C10H21 之 TSBTQ-10 (1)，藉由溶液製程
(shearing) 此新材料製成元件之電性可達 0.18 cm2V-1s-1，為此系列之
最高效能小分子。
另外本實驗室之前已開發具雙硫醚鏈 C10H21 之 p 型分子
DSDTT-10，元件電性可達 2.6 cm2V-1s-1。本研究繼續探討硫醚碳鏈
之鏈長效應，開發出硫醚鏈為 C8H17 之 DSDTT-8 (2)，藉由溶液製
程 (shearing) 此新材料製成元件之電性更高達 3.2 cm2V-1s-1，為此系
列之最高效能小分子。從所獲得之 DSDTT-10 與 DSDTT-8 之單晶
結構中我們發現引入硫原子於鏈中可幫助分子堆疊。且因硫醚鏈位於
同側，使得 DSDTT 核心可倆倆併排成”雙筒堆疊”，有利載子之傳遞。
本實驗室之前已開發具雙硫醚鏈 C14H29 之 p 型分子 SBT-14，
元件電性可達 1.7 cm2V-1s-1。本研究以此核心為板模，以硒取代硫原
子，開發出具硒醚鏈之 SeBT 新核心，為探討共軛與硒醚碳鏈之鏈長
效應，開發出五個 p 型小分子材料。從所獲得之 DDTT-SeBT-10 與
DDTT-SeBT-14 之單晶結構中我們發現引入硒原子於鏈中可幫助分
ii
子堆疊，使得分子間以磚型堆疊，有利載子之傳遞。其中 DDTTSeBT-
14 具有優異之電性表現高達 4.0 cm2V-1s-1，為目前台灣本土所
開發之可溶性 p 型有機薄膜電晶體小分子之溶液製程最高電性紀錄。 | zh_TW |
| dc.description.abstract | New small molecules based on TSBT, DSDTT, and SeBT cores have
been synthesized for organic thin film transistors (OTFTs).
For the first TSBT series, n-type TSBTQ-14 (TSBTQ with C14H29
chains) and TSBTQ-6 (TSBTQ with C6H13 chains) exhibited mobility of
0.14 cm2V-1s-1 and 0.10 cm2V-1s-1. To further complete the side chains
effect study, TSBTQ-10 (1; TSBTQ with C10H21 chains) was synthesized
and characterized. Via solution shearing, TSBT-10 exhibits the best
mobility up to 0.18 cm2V-1s-1 in this series.
For the second DSDTT series, DDTT-DSDTT-10 (DSDTT with
C10H21 chains) exhibited high mobility 2.6 cm2V-1s-1. To further complete
the side chains effect study, DDTT-DSDTT-8 (2; with C8H17 chains) was
synthesized and characterized. Via solution shearing, DDTT-DSDTT-8
demonstrates the best mobility up to 3.2 cm2V-1s-1. Both molecular
structures of DSDTTs were determined by single crystal X-ray diffraction
and exhibits two parallel face-to-face columnar stacking’s with a very close
interplanar core distance of 3.6 A .
For the third series, a couple new small molecules based on the
selenylated bithiophene (SeBT) with different end-capped aromatic groups
and alkyl chains were developed. DDTT-SeBT-14 (7; with C14H29 chains)
exhibits the highest mobility of 4.00 cm2V-1s-1 via solution shearing. The
molecular structures of DDTT-SeBT-14 and DDTT-SeBT-10 (6) were
determined by single crystal X-ray diffraction and showed brick-type
