| dc.description.abstract | 本論文主要合成出一系列具有推、拉電子結構的螢光放射團分子，希望藉此改變分子之螢光波長，以達較長波長之發光，且在分子設計上使之具有不共平面之共軛結構，這樣在固體時將有助於抑制分子內的轉動，使分子具有堆疊誘導發光的現象；另一方面，我們加入了以雙CN取代雙噻吩為主體的螢光放射團分子來測試其堆疊誘導發光的性質。
另外，利用熱重量分析儀與微差熱掃描卡計量測材料具有良好熱穩定性，利用循環電位儀與光電子光譜儀測量與計算得知化合物HOMO、LUMO能階，再利用密度泛函理論計算算出化合物最穩定結構以及含時變密度泛函理論計算HOMO與LUMO能階分子軌域的分布與其相對應之能階。 | zh_TW |
| dc.description.abstract | In this study, we synthesized a serious of fluorophore with various donor and acceptor substituents. The longer emission wavelength fluorophore can be adjusted by molecular design which nonplanar conjugated structure could restrict intramolecular rotation in solid state. Moreover, aggregation-induced emission phenomenon will be found in nonplanar conjugated structure. On the other hand, we added dicyano-substituented with dithiophene fluorophore to test their aggregation-induced emission behavior.
In addition, the thermal properties and the energy level of HOMO and LUMO were estimated by thermogravimetric analyzer, differential scanning calorimeter, cyclic voltammetry, and low-energy photoelectron spectrometer, respectively. Finally, the density functional theory and time-dependent density functional theory to imitate the orbital and energy levels of HOMO and LUMO. | en_US |
