摘要


在本篇論文中,成功的合成出含四-三氟甲苯與硫呋喃基鄰苯二甲醯亞胺兩個系列的化合物,並在此兩系列化合物的氮原子上接上不同的推電子與拉電子官能基,以進行研究兩個系列化合物的有機分子特性、不同比例的有機相/水相 (二氯甲烷 / 乙醇) 下,其螢光量子產率及光致發光性質。研究結果發現,含四-三氟甲苯基鄰苯二甲醯亞胺系列,無論在氮原子上接上butyl、toluene、……、等不同推電子官能基,最大的量子產率都落在乙醇 (Ethanol) 比例為0 % 時,且量子產率都非常低 (< 2 %) ; 當氮原子上接上benzylacetyl、benzylnitrile 等拉電子官能基,並無法順利得到我們預期的產物。含四-硫呋喃基鄰苯二甲醯亞胺系列,雖然在氮原子接上butyl、toluene 、……、 等不同推電子官能基後,其最大的量子產率大多落在乙醇比例為60–90 % 時,但量子產率一樣並不高 (< 8 %) ; 當在氮原子接上benzylacetyl 、benzylnitrile 等拉電子官能基,其產率分別只有 3.8 % 及 3.9 % ,結果與四-三氟甲苯基鄰苯二甲醯亞胺系列一樣,並無法進行有機化合物的螢光性質偵測。因此,本篇論文中,我們將針對四-三氟甲苯與硫呋喃基鄰苯二甲醯亞胺兩個系列的化合物,對實驗結果做一系列的探討與研究。

並列摘要


In this study, we designed and successful to synthesized two series of tetra – trifluoromethylphenyl or thiophenyl N – substituted phthalimides, and investigated there organic molecular characters and measured the UV – Vis and photoluminescence of this two series compounds in various ratio of ethanol / dichloromethane mixture. However, the experimental results showed that while the electron – donating units, like butyl, toluene, …… etc. functional groups of N – substituted phthalimide, the maximum quantum yield (Q.Y.) almost at the ethanol content of 0 %, and exhibited very low fluorescent (< 2 %) , and while the electron – accepting units, like benzylacetyl、 benzylnitrile etc. functional groups of N – substituted phthalimide, we could not get the compound that we expected. As the series of thiophenyl N – substituted pthalimide, although the maximum Quantum yield almost at the ethanol content of 60 – 90 % while the electron – donating units, like butyl, toluene, ……etc. functional groups of N – substituted phthalimide, the photoluminescence intensity were too weak (< 8 %). As well as the electron – accepting units, like benzylacetyl、 benzylnitrile etc. functional groups of N – substituted pthalimide, the yield of theses were too low to detect the photoluminescence, and the yield were 3.8 and 3.9 %, respectively. Thus, in this work, we have discussed against the two series of varies functional of compounds.
