摘要: | 本論文研究二苯乙烯衍生物與含五苯荑結構之金錯合物的光物理行為。第1章內容為基礎背景知識的簡要介紹,包含基本光化學、二苯乙烯衍生物的光化學、金(I)錯合物的性質、及五苯荑結構的性質與應用。第2章內容是探討間位胺基效應對剛硬性二苯乙烯衍生物之作用,並研究剛硬性二苯乙烯衍生物的剛硬性與平面性對間位胺基效應之影響。第3章內容是探討在具有強拉電子腈基的二苯乙烯衍生物加上間位胺基的取代時,是否會產生扭曲分子內電荷轉移態,並合成了環化個別單鍵的化合物來研究扭曲分子內電荷轉移態的結構。第4章內容是探討含五苯荑結構的金(I)異腈錯合物[Ph-Au-C≡N-Phip-OC8H17]的同質多晶形結構與光物理行為之關係。第5章內容是建立在第4章的基礎上,探討含有五苯荑結構之金(I)異腈錯合物[Ph-C≡C-Au-C≡N-Phip-OC8H17]的晶體孔洞之結構與刺激響應的光物理行為。 In this thesis, the photophysical behavior of stilbene derivatives and pentiptycene containing gold(I) complexes are investigated. In Chapter 1, we introduce some background, including basic photochemistry, photochemistry of stilbene derivatives, properties of gold(I) complexes, and features of the pentiptycene scaffold. In Chapter 2, we explore the application of the meta-amino effect in stiff-stilbene, and investigates the interplay between the rigidity and planarity of stiff-stilbene and the meta-amino effect on the fluorescence quantum efficiency. In Chapter 3, we investigate whether the meta-amino substitution could induce the formation of a twisted intramolecular charge transfer (TICT) state for stilbenes containing a strong electron-withdrawing group. Model compounds of constrained single bonds are synthesized to identify the single bond that is responsible for the TICT state. In Chapter 4, the correlation between the polymorph of a pentiptycene-containing gold(I) isocyanide complex [Ph-Au-C≡N-Phip-OC8H17] and the observed photophysical behavior is reported. In Chapter 5, we follow-up research of Chapter 4 and the results reveal that the new pentiptycene-containing gold(I) isocyanide complex [Ph-C≡C-Au-C≡N-Phip-OC8H17] adopts a porous supramolecular assembly in solid state and displays novel stimuli-responsive luminescence properties. |
