摘要(中) 本篇論文合成出四個含有醯胺基團的雙取代蒽衍伸物,探討凝膠片段末端碳氫鏈長度,以及蒽主體與凝膠片段之間有無乙炔基連接,對於形成凝膠的能力及固態刺激響應行為之間的差異。從凝膠測試結果來看,此四種化合物皆可在多種有機溶劑中形成凝膠。經由變溫1H NMR去探討形成凝膠的作用機制,推測可能是透過分子間醯胺基團氫鍵以及芳香族環間之π-π作用力進行自組裝排列。此外,分別透過變溫吸收光譜、放射光譜及改變濃度的吸收、放射及激發光譜,探討分子間聚集的作用力關係對於光物理性質的影響,推測四個分子皆形成H-type aggregation的堆疊模式,且透過凝膠以及薄膜的光譜探討,可以推測分子間堆疊的程度。溶液態分子會隨著環境中水含量的提升,而觀察到明顯地放光強度增加以及光色的改變,即典型的AIEE特性。利用SEM能觀察到微觀尺度下,分子間聚集後所形成的不同形貌,發現凝膠分子會依據分子間作用的程度,出現以纖維狀相互纏繞或針狀結構聚集。透過PXRD探討置備乾凝膠後,分子間的堆疊模式,發現分子間聚集排列較不有序,而觀察到非晶性的中間相結果。最後也研究了四種化合物的固態粉末刺激響應行為的差異及特性,在機械力刺激下觀察到固態放光顏色的改變,且可透過溶劑蒸熏的方式使放光顏色回復,並可重複數個循環。
摘要(英) In this thesis, we synthesized four anthracene-based disubstituted organogelators, FH76, FH146, FH158 and FH156. We made some structural modifications between these four compound, trying to figure out the different properties among them, including geling ability and solid state stimuli-response. We used anthracene as a core linked by gel segment at 2,3-position with different chain length by either ethynyl or single bond. From the gel test results, all four compounds formed organogels in various organic solvents. A variety of spectroscopic methods were employed to identify the driving forces responsive for gel formation and explored the photo-physical properties. It is speculated that the self-assembly arrangement occurs through intermolecular hydrogen bonding and π-π interaction. The stacking behavior suggests that all four molecules self-assemble through the H-type aggregation. It shows the typical AIEE property when gradually increase the water content in the THF solution, displaying the fluorescence intensity enhancement as well as color change. Different morphologies formed by intermolecular aggregation at the microscopic scale can be observed by SEM, and it is found that the gel molecules are entangled with each other in a fibrous form and aggregated in a needle-like structure. Also the intermolecular stacking patterns after preparing the xerogel were investigated by PXRD, and the mesophase results have seen which may come from the irregular stacking. Finally, the differences and characteristics of the solid state stimuli-response behavior of the four compounds were also investigated. It shows emissive color change upon grinding, and recover to the original emission when solvent fuming. The result is reversible and which can be repeated multiple cycles.
