以聯萘酚為主體之化合物及其電聚膜在陰離子感測器與液晶材料上的應用

Abstract

此篇論文主要分為兩個部分，第一部分為是以化合物1作為陰離子的感測器，我們藉由核磁共振實驗、紫外-可見光吸收實驗、螢光實驗與X射線單晶繞射實驗觀察化合物1與氟離子和其他陰離子的結合行為，其對氟離子有最好的辨識能力；另外化合物1與氟離子、氯離子、氫氧根離子會以一比二的方式結合，而與磷酸二氫根離子、醋酸根離子、對-甲苯磺酸根離子則是一比一的結合模式。也利用循環伏安實驗去探討化合物1與陰離子作用後，其氧化還原與電聚合情形的改變，並以化合物1的電聚膜做為電洞傳導層，討論其在OLED元件上的應用。

在論文的第二部分中，我們合成了一系列具三芳香環和聯萘酚的chiral dopant，測量其螺旋扭轉能力 ( HTP )，並依其結構的不同探討其HTP的差異，也將膽固醇型液晶置入液晶盒中，觀察其電光效應，發現有明顯的遲滯現象。最後試著利用此系列化合物的電聚膜做掌性轉移的實驗。

In the first part of this thesis, investigations of binding of compound 1 with various anions by NMR, UV absorbance, fluorescence, and X-ray diffraction experiments were carried out and binding constants were obtained. We find compound 1 complexes with F-, Cl-, and OH- to form 1:2 adducts and complex with H2PO4-, OAc-, and OTs- to form 1:1 adducts. Cyclic voltammetry was used to explore the redox properties of complexes and electropolymeric films were prepared. Finally, the electropolymeric film of compound 1 was used as the hole transport layer in OLED device.

In the second part of this thesis, a series chiral dopants with tert-aromatic ring and BINOL group were synthesized and the helical twisting powers (HTP) were determined. Then HTP dependent was discussed. Liquid crystals doped with chiral dopants showed the electro-optical hysteresis. Finally, transferring chirality to liquid crystal molecules by electropolymeric films was attempted.
