| dc.description.abstract | 延續實驗室之前開發具硫醚鏈噻吩的研究，開發出三大系列核心主體 BSTT, BSDTT 與 DSDTT，藉由改變硫醚碳鏈長度來改善此系列分子的溶解度與分子排列性，在這其中也得到 BSTTM 核心之單晶結構，證明了所設計分子的平面性，將此三種核心主體向外接上不同的共軛結構與官能基，合成出八個P-type以及三個N-type材料分子。其中以 DSDTTQ-10 (15)目前已有 0.168 cm2/Vs 之載子移動率表現。
第四系列是以硬端苯併環噻吩結構與軟端硫醚碳鏈所結合的分子設計，成功得到具有液晶特性之 OTFT 材料，藉由升溫形成液晶態後分子的重排現象來達到更高度的分子排列規則度，預期能達到更好的載子移動率表現。
第五系列核心是改良 BTT 盤狀核心結構，以不同之合成路徑以及分子設計上的修飾，成功得到兼具盤狀平面結構以及擁有良好溶解度之核心，將具有應用在溶液製程元件上之開發潛力
第六系列是以本實驗室已發表光電轉換效率可達 10.1 % 的有機染料 TPA-TTAR-TA 為基礎，將新開發之 BSTT 核心取代 TTAR，以相似之分子設計合成出兩個有機染料分子，目前以 TPA-BSTT-SCb8-TA (18) 已有 5.8 % 之光電轉換效率。 | zh_TW |
| dc.description.abstract | A series of novel materials based on BSTT, BSDTT, and DSDTT cores have been developed for organic thin film transistors (OTFTs). The highly planar BSTTM core was confirmed by single crystal structure. Eight p-type and three n-type materials were synthesized and characterized in this three series.
For the fourth series, three thioalkylated thiophene capped BTDTs were developed. BTDT-T-6 (11) and BTDT-T-10 (12) both exhibited liquid crystalline properties around 150 oC.
For the fifth series, four new BTT-based were developed which bearing C6 and C10 thioalkyl chains in different positions of BTT core. This series exhibits good solubility and good planarity for solution processed organic semiconductors.
For comparing with the highest PCE of organic dye TPA-TTAR-TA developed in our group, two new dyes, TPA-BSTT-SC14-TA (17), TPA-BSTT-SCb8-TA (18) were synthesized.
The optical and electrochemical (HOMO and LUMO) properties of these materials were characterized by UV-vis and DPV. Thermal properties were investigated by TGA. Currently, DSDTTQ-10 (15) exhibits the mobility up to 0.16 cm2/Vs, and the organic dye TPA-BSTT-SCb8-TA (18) exhibits the PCE up to 5.8 %. The OTFTs studies of the rest compounds are in progress. | en_US |
