Abstract:	在本論文中，我們合成了一系列以蒽為主體的有機凝膠分子，並在分子中引入了醯胺官能基團。其中具有長碳鏈的結構分子 (1A12C、9A12C、1,4A12C) 具有形成超分子凝膠的特性，而我們的目標是了解這些分子的主要作用力是什麼，並探討分子間可能的自組裝模式。為了達到這個目的，我們使用了變溫的1H核磁共振 (NMR) 和紫外可見光譜 (UV-vis) 等技術。期望透過這些實驗，觀察到凝膠形成過程中的分子間作用力，包括分子間的作用力、π-π作用力和碳氫鍵(CH-π)作用力等。這些作用力對於凝膠的形成和穩定起著關鍵的作用。此外，我們還合成了具有短碳鏈結構的凝膠分子(1A4C、9A4C、1,4A4C)，並嘗試透過結晶生長來得到不同螢光性質的單晶，比較這些凝膠分子在固態下的刺激響應測試結果，讓我們能夠獲取得更多螢光變色的機制和分子自組裝行為的相關信息。關鍵字：有機凝膠分子、超分子自組裝、蒽、醯胺、固態刺激響應、單晶;In this research thesis, we synthesized a series of organic gel molecules based on anthracene and introduced acylamide functional groups into the molecules. The molecules with long carbon chains (1A12、9A12C、1,4A12C) exhibited the ability to form supramolecular gels. Our objective was to understand the primary forces driving gel formation and explore possible molecular self-assembly patterns. To achieve this, we employed techniques such as variable temperature 1H nuclear magnetic resonance (NMR) and ultraviolet-visible spectroscopy (UV-vis). Through these experiments, we aimed to observe the intermolecular forces involved in gel formation, including molecular interactions, π-π stacking, and CH-π interactions. These forces play a crucial role in the formation and stability of gels. Additionally, we synthesized gel molecules with short carbon chains (1A4C、9A4C、1,4A4C) and attempted to grow single crystals with different fluorescent properties. By comparing the results of solid-state stimulus response testing for these gel molecules, we aimed to gain insights into the mechanisms of fluorescence color changes and molecular self-assembly behavior. Keywords: organogel molecules, supramolecular self-assembly, anthracene, amide, solid-state stimuli response, single crystal
