本實驗室研發並報導以噻吩為主體架構的不對稱新型分子具有液晶性質，因此我們延續並探討在噻吩架構做化學上的修飾，另外在聯苯位置接上帶有10個碳數的烷氧基及不含碳數的氫氧基，來量測這些分子的液晶性質。結果發現以2,5-噻吩為主體架構的分子具有液晶性質，且當尾端不管是長碳鏈或者是不含碳鏈的氫氧基，其架構都具有液晶性質。而當噻吩架構不是以2,5-位置作取代時，其不論尾端碳鏈的長短，此類分子就不具有液晶性質。
另一研究課題，近年來以噻吩和噻唑排列組成的架構在有機半導體材料研究受到高度的重視，因此我們利用本實驗室發表超音波巴比艾爾型式反應成功將雜環芳香族鹵化物製備成雜環芳香族有機錫化合物，再經由鈀金屬的催化下進行Stille 耦合反應，合成出以噻吩和噻唑互相排列組成一系列發出藍綠光色的新型有機發光材料。並期許能應用在有機半導體材料。另一方面，我們設計以噻吩和苯環排列的架構，在外圍接上帶有拉電子的官能基，使其整個架構為n-Type有機半導體材料。

Our laboratory developed and reported a serial of new thiophene-based compounds which exhibit liquid crystal property.  Thus, we continued plumbing the thiophene cored with chemical modification, and understanding the effectiveness of substitutional position.  In addition, we measured the liquid crystal property of those at biphenyl part which alkoxyl or hydroxyl group was attached.  Based on the results, the liquid crystal property was observed when the 2,5-substituted thiophene was located and the alkoxyl or hydroxyl group was connected at the end of biphenyl.
    
Another thesis topic was organic semiconducting material which has received much more attentions in recent years.  Thus, we designed and synthesized some new organic material, based on the combinations of thiophene and thiazole, and these compounds were observed to exhibit luminous properties.  The sonochemical Barbier-type reaction which was previously reported by this laboratory was used and successfully prepared heterocyclic organostannanes.  These organostannanes were applied to synthesize some potentially organic luminous and organic materials by using palladium-catalyzed Stille cross coupling reactions.
