摘要:	A部份摘要：藉著本實驗室研究無機液晶多年的基礎，我們試著整合兩個液晶的次領域，無機液晶和香蕉形液晶，來獲取新的物質特性。令人驚喜地，我們不但得到B7相的無機液晶，同時單晶繞射、粉末繞射和光電測試的實驗結果，也給了我們許多証據來解答過去B7相文獻中的疑問；進一步揭開B7相神秘面紗。 B部份摘要：我們成功地利用便利的合成步驟取得烷氧碳鏈取代的benzil，大大提升了過去無法達到的高合成效率，並利用我們合成出的benzil製造良好發光性質的quinoxaline液晶和鋅錯合物的無機液晶。高量子產率的液晶具有製造極化放光和高載子效率材料的潛力。 Abstract of series A: With the foundation of works at metallomesogens, we attempt on integrating these two sub-fields of liquid crystals, metal- containing and the fashion banana-shaped mesogens to achieve the new realm. Surprisingly, conspicuous fruitful results come into view. The first single crystal of a homologue molecule exhibiting B7 mesophase has been made. Combining the powder X-ray data and electro-optical measurements, astounding structural information are obtainted and suggest that previous investigations could be associated and there are proper answers to the doubts. Abstract of series B: We successfully synthesized alkoxy-substituted benzils, which were used to prepare quinoxalines and zinc (II) bis(quinoxalinol). Our results indicated that the products showed discotic mesophases, and the good quantum yields can give the potential of polarized luminescence and high carrier mobility.
