摘要:	我們利用3,4,9,10-perylenetetracarboxylic dianhydride（PTCDA)和1,4,5,8-naphthalenetetracarboxylic dianhydride（NTCDA)作為負型有機半導體材料主體結構。因負型有機半導體在空氣下傳導電子具不安定性，因此導入多氟烷氨基將酐類轉化成醯胺類（PTCDI和NTCDI)使其化合物在空氣中更加穩定，藉由改變多氟烷基的碳鏈長度探討其含氟多寡與距離對化合物在空氣下的相對穩定性的關係，並且將我們所合成的有機材料製成有機場效電晶體，量測到最佳載子移動率為0.02 cm2/Vs，並分析其電性結果關係。 In this study. We use 3,4,9,10-perylenetetracarboxylic dianhydride（PTCDA) and 1,4,5,8-naphthalenetetracarboxylic dianhydride（NTCDA) as our main structure. Due to n-type semiconductors are not stable in the air, we introduce the perfluoro-alkyl chains into our structure (PTCDI and NTCDI), anticipating that these organic semiconductors are more stable in the air. Here we prepare a series of n-type organic semiconductors based on perylene diimide and naphthalene diimide with different perfluoro-alkyl chains, conferring the numbers of fluorine and the distance from the core. Finally, we systematically investigated the effect of chemical structural variation on molecular level, electron mobility, and transistor stability.
