摘要

在1970代後期，共軛高分子被喻為下一代作為電子和光學設備之新材料。 而Polythiophenes因其電子特性和熱穩定性質更為共軛高分子中重要的代表性種類，polythiophene可應用於聚合物發光二極體(PLEDs)和有機場效電晶體(OFET)中。聚噻吩在共軛高分子系統中為結構型態最豐富之高分子。本實驗藉由改變聚噻吩之結構來探討其共軛高分子結構與其溫變色之關係。此研究乃以化學氧化聚合合成聚噻吩，導入矽氧烷鏈為側鏈基而使聚噻吩有新的光學、電學及溫變色效應。

另一方面，在本研究中合成一系列的非線性光學材料，為了增加聚亞醯胺的機械性質，將矽氧烷鍵結至產品上，再以FTIR、NMR研究其物性探討在光電工業上之應用。

In the late 1970s,conjugated polymers were proclaimed as futuristic new materials that would lead to the next generation of electronic and optical devices. Polythiophenes are an important representative class of conjugated polymers that form some of the electronic properties and thermally stable materials that can be used as polymer light emitting diodes (PLEDs) and organic field effect transistors (OFET).Polythiophenes are a series of conjugated polymers with diverse structure. The objectives of this work are the preparation of polythiophenes with various thermochromic via structure modification. In the study, the polythiophene is prepated by chemical oxidation polymerization. Bonding the thiophene with flexible siloxane, the conjugate polymers become new optical、electronic and thermochromic property.

On the other hand, a series of nonlinear optical polymers are synthesized in this research. Siloxane is bonded to PI to enhance its mechanical properties。Their potential applications in optical industry will be elucidated.
