此研究發展出一兩步反應合成1,4-二苯基稠四苯之方法，有別於先前由其他作者所發表之方法，並經由核磁共振儀氫譜、碳譜、質譜儀、高解析質譜儀等分析儀器，鑑定合成結果，純化產率較先前文獻提高約50%。在此研究中首先發表1,4-二苯基稠四苯光物理性質，1,4-二苯基稠四苯類化合物最大吸收波長在484至489nm、最大螢光波長在492至502nm，皆位於可見光區，且其螢光量子產率在0.3-0.4間，故此類分子有應用於發光材料之潛力。

In this study, we developed a new method of two-step pathway to synthesize a series of different substituted 1,4-diphenyltetracenes, which is different from the methods previously published by other authors. 1H NMR, 13C NMR, Mass and HRMS, We used UV-visible spectrophotometer and spectrofluorometer to discuss photophysical properties, which got the maximum absorption wavelength of different substituted 1,4-diphenyltetracene is 484 to 489 nm, and the maximum emission wavelength is 492 to 502 nm. They are all located in the visible region and their fluorescence quantum yield is between 0.3 and 0.4. Such molecules have the potential to be applied to luminescent materials.
