這個研究發現了,導電高分子聚(三-已基噻吩)(P3HT)可以和六甲苯
(HMB)形成二元共晶系統(eutectic binary system)。高分子與小分子的共晶析出,在基礎科學上的認識尚不多,因此這一個階段的研究以建立相圖
為主要的目標。研究的方法是藉由獲得等溫即時的X-ray 繞射以及熱分析
曲線,來分析多階段的晶相析出與熔融現象。
依據晶相的熱穩定性,可初步決定共晶成份介於66 wt % 至67 wt %
的P3HT 組成之間,共晶溫度則為1411 oC。此外,此研究發現在第一
階段的HMB 晶相析出之後,由於P3HT 晶相無法與HMB 的晶格排列產
生良好的匹配(lattice match),因此P3HT 分子會聚集成液晶相析出。因為液晶相的流動性以及HMB 晶相在薄膜內的二維延伸成長,由偏光顯微鏡
的觀察證實,P3HT 液晶相的析出可以形成大於一公釐(mm)的連續分佈,
因此將對共軛導電高分子的應用造成衝擊。
For the transportation of charge carrier with thin film of conjugated polymers, it is essential to have defect-free continuous crystalline domains widely extended as the channels. For the most studied conducting polymers
P3HT, the assembly and crystal growth mechanisms have not been well understood, and only limited extent of crystallinity, less than 30%, has been reached. Therefore it is important to generate new understanding of low
dimensional polymer physics for enhancing crystallinity, and optimizing crystal orientation and morphology. For discovered eutectic binary systems composed of conjugated polymers and small organic molecules, disparate crystallization sequences were unveiled via the change of composition. It is possible to design and construct hierarchical structures within thin film via eutectic system. While the component of small molecule crystallizes first, the following epitaxial crystallization of conjugated polymers was found able to form large scale of continuous edge-on crystalline lamellae as being guided
by underneath crystalline substrate. Nevertheless, while lattice match is not available, the liquid crystalline phases were proposed to develop instead.
The P3ATs represent a class of conjugated polymers widely used as the hole-transporting material in organic field-effect transistors (OFETs). The interested transportation properties were recognized strongly depends on the
molecular parameters, and processing conditions. It is because these factors are all capable of causing the changes in two-dimensional molecular ordering in the thin film. The purpose of this research is to establish the phase diagram of eutectic binary systems of conjugated polymers, and explore the impact of crystallization route and epitaxial relationship to the crystal growth habit for enhancing thin film performance.
