本實驗室已廣泛地研究過許多不同種類的聚苯胺衍生物，而目前一個有趣又熱門的題目，便是聚苯胺在有機發光二極體中當作電洞注入層的應用，其中針對聚苯胺衍生物在這方面所做的研究，則是比較少的。本研究主要是利用磺酸根改質導電性高分子聚二苯胺，在發煙硫酸下使其磺酸化，我們以紫外光-可見光光譜、傅利葉轉換紅外線光譜、熱重分析法與元素分析儀來特徵分析磺酸化之聚二苯胺的系統，此外，我們更進一步組裝有機發光二極體，利用此高分子來當作電洞注入層，並且選擇MEH-PPV為發光層的有機發光二極體元件，來探討聚二苯胺摻雜樟腦磺酸對於元件性質的影響。
　　此外，利用發光物質的摻混來提高發光效率也是近來研究的方向。在主客發光材料系統底下能有效的增加發光色純度、發光效率。適當的材料選擇、與調配比例都是改進元件效能的關鍵。本研究利用三種主鏈結構相近的發光高分子做兩種系統的探討。我們以紫外光-可見光光譜、螢光光譜電激發光光譜、元件的電流-電壓-亮度曲線、原子力顯微鏡、能階圖，嘗試探討不同摻混系統對元件行為的影響

　　Many polyaniline (PANI) derivatives have been extensively studied in our laboratory. It is an interesting topic to understand what effects will present in the polymer light emitting diodes (PLED) device using PANI derivatives as the hole-injection electrode. Although various reports on PANI from this aspect are available in literature, little attention has been paid to substituted derivatives of PANI. In this work, conducting polymer, poly (diphenylamine) (PDPA), was modified by sulfonic acid group. Sulfonated poly (diphenylamine) (SPDPA) was synthesized by using fumic acid to sulfonate EB-PDPA and characterized through the examination of UV-Vis spectral, FTIR spectral, TGA and Elemental Analysis. In addition, the PLED was fabricated using SPDPA as a hole-injection layer for studying the performance and simultaneously comparing with PLED using PEDOT-PSS as hole injection layer.
　　It has been an interesting topic in light emitting diode that blending guest with host molecules to improve device efficiency. The emission color can be changed and the brightness is increased by doping the emitter (host) with fluorescent dye (guest). The key points to the improvement depend on appropriate selection of emitting materials, blending ratio. In this research, two polymer blend systems with similar polymer backbone structure were investigated through UV-vis absorption, EL, PL spectra, current-voltage-luminance curves, AFM images, energy diagram.
