Due to unstable conformation of o-MePyGFP; However, we successfully synthesized o-PyPhGFP via molecular adjustment. o-PyPhGFP underwent excited-state intramolecular proton transfer process via seven-membered-ring hydrogen-bonding system and its emssion at 607 nm. Also, ZnCl2 was reacted with o-PyPhGFP to form a complex, which destructed intramolecular H-bond and obtained blue emission. In part II, according synthetic route from chapter1, 5-HI and 7-HI were used as starting reactants to obtain a structurally locked GFP core chromophore p-LHBDI, its ortho-derivative, o-LHBDI underwent ESIPT process and enhanced the quantum yield (up to 0.18) at 585 nm. We also synthesized H2BDI possessing both para- and ortho- hydroxyl groups. Anionic H2BDI rendered its emission at 557 nm and quantum yield of 1.3 x 10-3. In part III, 1,2-dibromocyclopent-1-ene was used as starting reactant to link pyridine and pyrrole to obtain the novel compound, 7-HB, possessing intramolecular seven-membered-ring H-bond system. 7-HB rendered tautomer emission at 603 nm. Also, we obtained the methylated compound, 7-NCH3. In part IV, three compounds (8-HB-1, 8-HB-2 and 8-HB-3) which were successfully synthesized may have intramolecular eight-membered-ring H-bond system.摘要 i Abstract ii 目錄 iii 第一章 1 1-1 緒論 1 1-2 實驗設計 6 1-3 實驗結果與討論 7 1-4 結論 12 1-5 合成步驟 13 1-6 參考文獻 18 第二章 20 2-1 緒論 20 2-2 實驗設計 21 2-3 實驗結果與討論 22 2-4結論 29 2-5 合成步驟 30 2-6 參考文獻 34 第三章 35 3-1 緒論 35 3-2 實驗設計 37 3-3 實驗結果與討論 38 3-4 結論 40 3-5 合成步驟 41 3-6 參考文獻 43 第四章 44 4-1 緒論 44 4-2 實驗設計 45 4-3 實驗結果與討論 47 4-4 結論 49 4-5 合成步驟 50 4-6 參考文獻 55 附錄 565370181 bytesapplication/pdf論文公開時間:2019/07/09論文使用權限:同意有償授權(權利金給回饋本人)綠色螢光蛋白質分子內氫鍵合成具七員環氫鍵系統的激發態分子內質子轉移化合物Synthesis of Excited-State Intramolecular Proton Transfer Compounds via Seven-Membered-Ring Hydrogen Bonding Systemthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/261350/1/ntu-103-R01223130-1.pdf
