中文摘要 本篇論文成功合成出以苯並雙唑(Benzobistrazole)為核心結構的烷鏈區域異構化單元並透過更換不同的推電子基來合成出一系列的對稱型螢光分子該系列模型分子簡稱BBTA系列，再將這些分子進行液態的線性光學量測以及放大自發輻射(Amplified Spontaneous Emission；ASE)的量測，在經過一系列的光學性質量測後我們將數據結果與結構分子進行探討可以得到以下的結論: (1)在BBTA系列中，不同推電子結構單元均會對分子吸收及螢光光譜產生影響。 (2)在相同推電子結構單元的BBTA系列中，不同區域異構化均會對分子生命週期產生影響。 (3)在所有的模型分子中皆有良好的螢光量子產率，在液態中的螢光量子產率有99%，可作為高效的螢光材料。 (4)在BBTA系列中的模型分子對不同溶劑做溶劑效應影響。 (5)在BBTA系列中的模型分子皆測量出ASE的行為且具有較低的ASE閥值，在做為有機固態雷射材料方面是很有潛力的增益介質。;Abstract We have successfully synthesized an alkane chain regioisomerization unit with benzobistrazole as the core structure and synthesized a series of symmetrical fluorescent molecules by replacing different electron-donating groups. This series of model molecules is referred to as the BBTA series. These molecules were then subjected to liquid linear optical measurements and amplified spontaneous emission (ASE) measurements. After a series of optical quality measurements, we discussed the data results with the structural molecules and obtained the following conclusions: (1) In the BBTA series, different electron-pushing structural units will affect the molecular absorption and fluorescence spectra. (2) In the BBTA series with the same electron-pushing structural unit, different regional isomerizations will have an impact on the molecular life cycle. (3) All model molecules have good fluorescence quantum yields, with a fluorescence quantum yield of 99% in the liquid state, making them highly efficient fluorescent materials. (4) The model molecules in the BBTA series are affected by solvent effects in different solvents. (5) The model molecules in the BBTA series all exhibit ASE behavior and have low ASE thresholds, making them very promising gain media for organic solid-state laser materials.
