含有超分子結構之共軛樹枝狀高分子的合成與能量轉移之探討

Abstract

本論文主要是在合成出具有超分子氫鍵性質的奈米複合材料，並探討其之間的能量轉移效應，我們首先合成具有Thiol官能基之perylene bisimide的表面修飾材料，將其分別命名為T-PNH及T-PC6，並且合成了氧化鋅奈米棒，目的為增加電子傳導出去的機率。最後利用氫鍵受體及氫鍵給體理論，我們成功合成出擁有2,4-bis(ethyl-amino)-1,3,5-triazine結構的塞酚樹枝狀高分子，將其命名為15T5N。 期待此類的奈米複合材料藉由氫鍵的形成，能有良好的能量轉移效應，未來可以應用於太陽能電池及化學感測材料上，來增進效率以及感測靈敏度，這些奈米複合材料利用ESCA、變溫FT-IR、UV-visible、PL、TGA、CV以及TEM來進行物性探討，最後利用TRPL來探討能量以及電子轉移的效應。

The aim of this thesis is to synthesize the nano-composites with supermolecular hydrogen-bonded properties, and to investigate the energy transfer effect among these nano-composites. Above all, we successfully synthesized two kind of surfactants of perylene bisimide with thiol group were synthesized and named as T-PNH、T-PC6, which is to compare the differences to the energy-transfer properties. Moreover, ZnO nanorods was been synthesized can lead to an improved transport probability of electrons and energy. Sequentially, based on the principle of hydrogen-bonding donor and acceptor, thiophene dendrimer with 2,4-bis(ethylamino)-1,3,5-triazine was synthesized and denominated as 15T5N. We expected that these nanocomposites will have favorable energy transfer effect by means of formation of the hydrogen bonding, which could lead performances of photovoltaic cell and chemical sensor to improve in further investigations. The identification and the investigation of photophysical properties were researched by ESCA、FT-IR、UV-visible、PL、TGA、CV and TEM. Finally, we use the TRPL to investigate the effect of energy transfer and electrons transfer.
