我們利用文獻38合成出一系列的三氮雜苯衍生物，並應用在有機電激發光元件的電子傳輸層上，觀察他們在電子傳輸層上元件的效能。另外，我們導入n形摻雜層的概念，將具有n形摻雜特性的LiF摻雜到我們合成出的衍生物中來當作電子傳輸層，目的在於改進電子傳輸層的電子注入效力，使元件的效能獲得改善。

In this dissertation we use the references to form a series of 2,4,6-triphenyl-1,3,5-triazine derivatives and apply to the electron transfer layers of the organic light-emitting device, observing the efficiency of their elements’ electron transfer layers. Besides, we add the concept of n-doped layers and mix LiF with the functions of n-doped layers to our components as the electron transfer layers. The main purpose is to improve the efficiency of electron transfer layers so that the efficiency of elements can also be improved.
