至今文獻中,很少有關cyclophosphazene衍生物的紫外光-可見光吸收光譜,螢光光譜與電化學性質的探討,而對於在有機電激發光材料中,更可以說是沒有,因此本論文中合成了一系列的cyclophosphazene 衍生物,有鑒於現今常用的OLED電子傳輸材料Alq3 ,低mobility,小bandgap與昇華時ashing等缺點.因此,希望cyclotriphosphazene的高熱穩定性,及相當低的HOMO與LUMO值能應用於OLED,而phosphonitrilic chloride trimer的LUMO值3.95 eV HOMO值8.45 eV .因此所合成出來的化合物一如預期的,即HOMO介於6.18~7.69 eV 而LUMO介於3.1~3.6 eV, 其吸收範圍均在紫外光區(250-354 nm) PL的放光範圍亦在紫外光區(300-350nm) 因此材料本身並不影響元件所放光的位置, 所以預期在OLED的元件上的表現能比Alq3較佳.因此,在未來的研究上,將cyclophosphazene衍生物應用在電子傳輸與電洞阻擋材料或發光主體材料(host)上,是一個可以嘗試的方向.
