| 摘要: | 軟性電子是全球各主要半導體與光電產業廠商研發競爭的主戰場，有機薄膜電晶體(Organic thin-film transistors, OTFTs)亦是因要達成此一目標而蓬勃發展。雖然有機半導體材料已有很大的進展 (五環素目前載子移動率已可達5 cm2/Vs) ，但絕大部份的材料，例如五環素(Pen)、噻吩蒽(ADT)、併環的噻吩(FT)之溶解度卻不佳，因而限制這些材料於溶液製程的應用。所以在這個計劃的主要開發項目中，我們將開發具良好溶解度之高載子移動率的併環噻吩(FT)材料。最特別的是因N型的有機半導體在p-n junctions, bipolar transistors, and complementary circuits是很重要的材料，目前已開發出的例子具高載子移動率的並不多，具高溶解度的更是稀少。研究顯示將P型有機半導體分子進行拉電子基的修飾之後(ex：F、CN、CO)可望改變其傳導性，因此在這個計劃裏中，我們將特別同時進行可溶性的N型併環噻吩半導體材料之開發，並進行其電性之探討。 ; Organic field-effect transistors (OFETs) have attracted intensive attention for potential applications in flexible displays, low-cost electronic papers, RFID components, and smart textiles, as well as smart memory/sensor elements in the automotive and transportation industries. However, among the developed OTFT materials, most of the organic small molecules, such as pentacenes (Pen), anthradithiophene (ADT), and fused-thiophenes (FT) are not very soluble and preclude their potential used in the solution process. Herein for this proposal, soluble semiconductor materials based on the fused-thiophene (FT) system will be developed, characterized, and their OFET performances will be examined. Particularly, since n-type materials are crucial for the fabrication of organic p-n junctions, bipolar transistors, and complementary circuits, new fused-thiophene candidates suitable for electron transport will be developed and their OFET performance will be investigated. ; 研究期間 9708 ~ 9807 |
