摘要: | 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. |
