本論文目的主要合成含有烷基取代環四芴四烯分子，並對其分子進行基本結構鑑定。藉由順式乙烯基連結之含有烷基取代環四芴分子可利用其前驅物：tetrathia[3.3.3.3]phane經由分子內重排、氧化反應以及熱分解後而製得環四烯分子。分子結構可藉由核磁共振儀(NMR spectroscopy)、質譜(Mass spectrometer)和愛克斯射線單晶繞射儀(X-ray crystallography)加以佐證。此外，此環四烯分子的光學性質、熱性質、電化學性質亦在本論文中被建立與探討。除了基本之性質鑑定，我們發現環四芴四烯分子可藉由紫外燈光照射進行光氧化反應得到線性的trans diformyl octaoctyl substituted fluorenevinylene分子，並藉由核磁共振儀、質譜鑑定其結構，其光學性質、電化學性質亦被建立與探討。相關含有烷基環四芴四烯分子之開環歧化聚合反應目前正在進行中。

The aim of this thesis was to synthesize and characterize octaoctyl-[2.2.2.2](2,7)-fluorenophanetetraene. The fluorenophanetetraene composed of fluorene units linked through cis vinylene linkages can be synthesized through their corresponding tetrathia[3.3.3.3] fluorenophane in three steps including benzyne rearrangement, oxidation and pyrolysis. The final fluorenophanetetraene was fully characterized by 1H NMR, 13C NMR, Mass spectroscopy and X-ray crystallography. In addition, the optical, thermal and electrochemical properties of the fluorenophanetetraene can be examined and investigated. The photooxidation of the fluorenophanetetraene can be proceeded by UV light irradiation to give the all trans linear diformyl octaoctyl substituted fluorenevinylene. The optical and electrochemical properties of fluorenophanetetraene and it ring opening linear compound have been investigated and compared. Ring-opening metathesis polymerization of fluorenophanetetraenes is currently under investigation.
