摘要: 本篇論文主要探討三級膦與烯炔類化合物的反應機制,並討論在三級膦的催化下,化合物3與碳六十進行反應時的情況。在設立最佳反應條件後,使用一系列烯炔類化合物與碳六十反應,並經由光譜分析與X-ray單晶繞射鑑定出碳六十衍生物的結構並推測其反應機構。將獲得的產物應用於有機太陽能電池n型材料,並量測光電轉換效率,其表現與PCBM相當,具有成為新一代n型材料的潛力。
In this thesis, we revealed a phosphine-catalyzed [3+2] cycloaddition of compound 3 with [60]fullerene in a good yield. The reaction proceed through initial nucleophilic 1,3-addition of phosphine to alpha-carbon of 3 that forms reactive 1,3-dipoles followed by cycloaddition with [60]fullerene. The condition optimization, reaction scope, characterization and mechanism related to the formation of the proposed [60]fullerene products are also provided. The structures of these substrates are characterized spectrometrically and supported by single crystal X-ray diffraction analysis. These derivatives possess a general trend of LUMO energy levels as the typical n-type material, PCBM. The selected fullerene derivatives were used as n-type materials in efficiency study of organic photovoltaic devices, and they show great potentials to be alternative n-type materials in the near feature.
