本研究中以1,4-二噻吩萘為分子骨架，利用具有共軛結構的取代基修飾，合成一系列新的共軛延伸分子，藉由可見光紫外光分光光譜儀、螢光分光光譜儀測量分子吸收波長、放光波長、消光係數、螢光量子產率等光物理性質，並透過這些實驗所得到的光物理性質配合電腦理論計算探討分子構型對分子共軛性提升與吸收及螢光波長紅移的效果。

In this study, we synthesize a series of new molecules with extended conjugation system, containing 1,4-Di(thien-2-yl)naphthalene skeleton and substituent with π- conjugation system. Measuring the absorption and fluorescence spectrum, extinction coefficient, fluorescence quantum yield by using ultraviolet spectrometer and fluorescence spectrometer. Combine the photophysical properties and computation of the molecules to discuss the effect of molecular structure on π-conjugation improvement, absorption and fluorescence spectrum red-shift.
