In the thesis, an aldehyde-terminated poly(phenylene vinylene) (PPV) wasynthesized by Siegrist polycondensation method, and the polymer had a number average molecular weight of 5000g/mol with narrow polydispersity. In addition, a monodispersedomopolymer living anion of poly(2-vinyl pyridine) (P2VP) was synthesized via anionic polymerization using sec-butyllithium as an initiator. Block copolymers of PPV-b-P2VP were synthesized by a nucleophilic addition reaction between P2VP living anion and aldehyde-terminated PPV. Five PPV-b-P2VP block copolymers with different PPV/P2VP molar ratio were successfully synthesized with high yield (>90%). The synthesized PPV-b-P2VPs were characterized by using various techniques including gel permeation chromatography (GPC), UV-VIS, photoluminescence (PL), TGAthermogravimetric analysis) and differential scanning calorimetry (DSC). Furthermore, the self-assembling behavior of block copolymers was investigated by using TEM. Different microphase structures, e.g. lamellae, cylinders, and spheres were observed for differentompositions of the copolymers. In the end, we used the wide angle X-ray scattering technique to study the crystalline structure of PPV in the PPV-P2VP nanostructure. It was found that the crystallinity of PPV decreases with increasing P2VP molecular weight.摘要.....................................................IBSTRACT................................................II錄...................................................III目錄...................................................V目錄................................................VIII一章 緒論..............................................1二章 文獻回顧..........................................3.1 塊狀共聚高分子.......................................3.1.1 介紹...............................................3.1.2 硬桿-柔曲塊狀共聚高分子及其合成方法................5.2 Poly(p-phenylene vinylene)s （PPVs）................10.2.1 合成方法..........................................10.2.2 光學性質..........................................22.3 陰離子聚合..........................................24.3.1 陰離子起始劑 ......................................24.3.2 陰離子聚合之單體與反應機制........................24.3.3 特殊尾端官能基之陰離子聚合........................26.4 含DEH-PPV系列之塊狀共聚高分子及其自組裝行為.........28三章 實驗.............................................30.1 實驗藥品............................................30.2 儀器設備............................................32.3 實驗步驟............................................33.3.1 合成DEH-PPV.......................................33.3.2 陰離子聚合........................................37.3.3 合成塊狀共聚高分子 DEH-PPV-b-P2VP.................43四章 結果與討論.......................................45.1 DEH-PPV及其單體合成之鑑定...........................45.1.1 單體合成之鑑定....................................45.1.2 DEH-PPV合成鑑定...................................46.2 P2VP 合成之鑑定.....................................48.3 塊狀共聚高分子DEH-PPV-b-P2VP合成之鑑定..............49.4光學性質分析.........................................50.4.1 UV / Vis光譜分析..................................50.4.2 PL光譜分析........................................50.5熱性質分析...........................................51.5.1 TGA ...............................................51.5.2 DSC ...............................................51.6 DEH-PPV-b-P2VP之微結構分析..........................52.6.1 TEM影像分析.......................................52.6.2 WAXS圖譜分析......................................52五章 結論.............................................55考文獻................................................57錄....................................................60application/pdf6977088 bytesapplication/pdfen-US硬桿-柔曲塊狀共聚高分子聚對苯乙烯聚2 乙烯陰離子聚合尾端偶合反應自組裝行為rod-coil block copolymerpoly(phenylene vinylene)poly(2-vinyl pyridine)anionic polymerizationend-coupling reactionself-assembling behaviorthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/183114/1/ntu-97-R95549022-1.pdf
