| Abstract: | 利用醯胺鍵生成,合成出以三苯胺為主體的風扇狀三苯胺樹枝狀分子G0 與G1 以及運用Knoevenagel Reaction 合成出以氰基二乙烯苯為主體的三苯胺樹枝狀分子C0 與C1。並利用熱分析,光譜分析,顯微鏡與電化學方法來探討各別分子的熱性質,光物理,奈米結構與電化學特性。
而所有的分子都具有很特別的誘導聚集放光(aggregation-induced emission,AIE)或著是聚集誘導增強放光(aggregation-induced enhance emission,AIEE)等固相放光的特性是藉著分子內轉動限制(restriction of intramolecular rotation,RIR)或在固態時分子的排列模式所誘導。 而在不同的分子引入三苯胺基團都可利用電化學方式誘導分子聚合成高分子,以及所形成的高分子薄膜在氧化還原過程中具有電致變色特性的功能,最特別的是可以藉著電化學的氧化還原來控制固相螢光的開關行為。 我們發展出了一個簡單利用電化學方式來控制固相螢光特性的方法,可以應用到不同的光電元件上。 We used amide bond formation and Knoevenagel Reaction to synthesize propeller-shaped triphenylamine-based dendrimers G0, G1 and the others C0, C1 which utilize cyanostilbene as core unit. By using thermal analysis, spectroscopy, microscopy, electrochemical method, we could observe their thermal, photophysical, nanostructure and electrochemical properties. All the aggregation-induced emission (AIE) or aggregation-induced enhance emission (AIEE) character of them, by restriction of intramolecular rotation (RIR) mechanism or through molecular structure packing arrangement in the solid-state. The triphenylamine group can be polymerized by electrochemistry and the polymer film have electrochromic character. The most special thing that we can control the switching behavior of the solid state emission by electrochemistry. The property can be applied in various electronic devices. |
