此篇研究使用以光化學反應及多種有機聯氨改質單壁奈米碳管，並且經過葡萄糖、氫氧化鉀、二甲基亞碸於熱環境中還原有機聯氨上的硝基，嘗試將於空氣中呈現P型載子極性的單壁奈米碳管還原為空氣中穩定之N型奈米碳管，藉著誘導效應結合共軛效應具拉電子效果的硝基轉為推電子基氨基，以此立論預期氨基之親水效應及推電子效應使奈米碳管具備高分散性及N型效應以利於後續之各種應用。
實驗中以一般表面觀察如樣品分散性，直接證明改質還原效應的成功，並且由掃描式電子顯微鏡觀察樣品表面形貌，得知單壁奈米碳管結構並無被破壞。經由光譜測量如紫外-可見光光譜儀定位硝基、氨基特徵峰值的消長以判定改質還原反應之效果，而拉曼光譜則可為改質還原奈米碳管提供結構品質之訊息，得知有機聯氨具備如一般聯氨氮自由基增加碳管品質之趨勢。而電性分析如四點探針量測，配合厚度量測得知改質還原後奈米碳管之導電率並無明顯差異，且經過一系列有機聯氨進行載子霍爾係數量測以推拉電子基相位及共軛效應或苯環親電取代定位效應推論官能基位置對於P/N摻雜的影響，並得到最終以re(3-NPHCNTs)為最理想之N型摻雜單壁奈米碳管。

In this study, a photochemical reaction and many kinds of organic hydrazine be used to modify single walled carbon nanotubes, and the nitro groups on the organic hydrazine was reduced to amino groups in a hot environment by glucose, potassium hydroxide and dimethyl sulfoxide. The single-walled carbon nanotubes exhibiting the polarity of the P-type carrier in the air are reduced to N-type carbon nanotubes which are stable in the air. The nitro groups on organic hydrazine which has the electron-withdrawing effect because of combination of the conjugate effect and induction effect. On the other hand, amino groups which has hydrophilic effect and electron-withdrawing effect make carbon nanotubes have high dispersibility and N-type effect for subsequent applications.
In this study, the appearance of product, such as sample dispersibility, was used to directly prove the success of the reduction effect. And the surface morphology of the sample was observed by scanning electron microscopy, which indicates the structure of the modified and reduced single-walled carbon nanotube was not destroyed. The nitro group is measured by spectroscopy measurement, such as ultraviolet-visible spectrometer, and the peak of the amino characteristic determine the effect of the modification and reduction reaction, while the Raman spectrum provide the structural quality information for the modified and reduced carbon nanotube. Organic hydrazine has a tendency to increase the quality of carbon nanotubes, like general hydrazine effect. The electrical analysis, such as four-point probe measurement, combined with the thickness measurement, found that there is no significant difference in the conductivity of the carbon nanotubes after the modification and reduction, and the series of organic hydrazine is used and measure the carrier Hall coefficient. Push-pull electron-based orientation and conjugate effect or orientation effect of electrophilic aromatic directing groups infers the influence of functional group position on P/N doping, and finally obtains the ideal n-type doped single-walled carbon nanotube with re(3-NPHCNTs).
