摘要
本篇研究以喹喔啉主體修飾氰基、咔唑和叔丁基咔唑，合成兩個新型的橘紅色放光分子，分別為6-CNQxCz和6-CNQxtCz。最大放射波長為600 nm和606 nm，使用了理論計算得喹喔啉與咔唑及叔丁基咔唑之間的二面角分別為50.4°、50.1°及56.4°、58.4°。 第二部分研究，將己烷醯胺及癸烷醯胺，修飾FeIII-TAML上，成功合成出具有不同碳數的烷醯胺四醯胺基大環配體，BYD及BYF兩個分子。BYF在濃度為1×10-5M，五分鐘內分解90%的甲基橙。BYF在DMSO中相對於FeIII-TAML有較好的穩定性；溶液為ACN時分解效果優於FeIII-TAML。

In this work, two molecules constructed by linking quinoxaline-carbonitrile with two carbazole or t-butyl carbazole moieties as donor, i.e., 6-CNQxCz and 6-CNQxtCz. Density functional theory calculations showed that the dihedral angle of the molecules using carbazole as donor were 50.1°and 50.4°, which are much smaller than that using t-butyl carbazole as donor were 56.4°and 58.4°. The maximum emission wavelength of 6-CNQxCz and 6-CNQxtCz were at 600 nm and 606 nm. The second part, two molecules constructed by linking FeIII-TAML with hexanamide or decanamide, i.e., BYD and BYF. BYF demonstrated to decompose 90% of methyl orange within five minutes. The stability of BYF was better than that of FeIII-TAML in DMSO. The decomposition efficiency of BYF was superior to that of FeIII-TAML in ACN.
