中文摘要
本論文係利用茀(fluorene)為原料，以Suzuki reaction聚合反應製備含茀的發光高分子材料Poly (2,7-fluorene)，並經由EA、NMR、DSC、TGA、IR、UV-visible、PL（光激發光）光譜數據及EL(電激發光)測試，以探討Poly (2,7-fluorene)系列發光高分子材料之結構、物性及光電性質影響。
在高分子的物理性質方面，所合成Poly (2,7-fluorene) 具有良好的熱穩定性 (Td ＞270℃)，而含有1,3,4-二環或1,2,4-三環之茀的共聚合物擁有較高的玻璃轉移溫度 (Tg)。在溶解度方面，所合成的高分子皆可溶於一般常見的溶劑如：甲苯、四氫喃、氯仿、二氯甲烷等。
初步的PL結果發現在茀9號位置接上乙氧基，有助於其發光強度的增加。而含有1,3,4-二環或1,2,4-三環之茀的共聚合物，具有較高的發光效率。
元件的製作方面，以旋轉塗布(spin-coating)的方式成膜而製成單
層元件。P3與P4，其最大亮度分別為3.16與11.99燭光。而P5與P7在16伏特有最大亮度35.61與16.61燭光，P6則在15伏特有最大亮度32.43燭光。
Abstract
In this paper, the light-emitting polymers (poly (2,7-fluorene)) were prepared by Suzuki-type reaction. using fluorene as a starting material. The struture , physical and photoelectronic properties for a series of poly (2,7-fluorene) were studied by elemental analysis, DSC and TGA analysis, NMR, IR, UV-visible, PL and EL spectum analysis.
According to the results of TGA tests , we found all synthesized polymers have good thermal stability (Td ＞270℃) and the copolymers with 1,3,4-oxadiazo rings or 1,2,4-triazo rings exhibit higher glass transition temprature (Tg). Furemore, the synthesized polymers are soluble in organic solvents such as toluene, tetrahydrofuran, chloroform and dichloromethane.
From the PL spectrum analysis, the emitting intensity of polymers synthesized from fluorene with ethoxyl carbonyl group in 9th carbon were inhanced and the copolymers containing 1,3,4-oxadiazo rings or 1,2,4-triazo rings give higer emitting efficiency .
As to the EL test for synthesized polymers the single-layer EL device was prepared by a spin-coating procedure. The results indicsate that the maximum brightness for the polymer P3 and P4 was 3.16 and 11.9 cd/m2, respectively ; for polymer P5 and P7 operating at 16 volt at show the maximum brightness 35.61 and 16.61 cd/m2 cd/m2 , and for the polymer P6 operating at 15 volt show the maximum brightness 32.43 cd/m2.
