摘要
蒽和芘衍生物因其优异的荧光特性而被广泛研究用作光电器件中的发光材料。本研究利用铃木交叉偶联反应成功合成了两种新型蒽和芘蓝色荧光团（PAP 和 PTATP），并阐明了它们的光物理特性。具有加长 p 共轭体系的 PTATP 在 475 纳米波长处具有绿蓝色区域的荧光发射最大值，而共轭长度较短的 PAP 则在 442 纳米波长处发出纯蓝色发射峰。在各种溶剂中对吸收和发射光谱的研究发现，这两种化合物都能产生与溶剂无关的光谱，这是因为它们都是非极性分子。此外，在高水分溶剂中记录发射光谱时，还观察到了聚集引起的淬灭现象。
Anthracene and Pyrene Derivatives as Blue Fluorophores: Synthesis, Characterization and Photophysical Properties
Ant hracene and pyrene derivatives have been widely studied as emitting materials in optoelectronic devices due to their excellent fluorescence properties. In the present study, two novel blue fluorophores from anthracene and pyrene (PAP and PTATP) were successfully synthesized using a Suzuki-cross coupling reaction and their photophysical properties were elucidated. PTATP with an extended p-conjugation system had a fluorescence emission maximum in green-blue region at 475 nm, whereas PAP, with a shorter conjugation length, emitted pure-blue emission peak at 442 nm. The study of absorption and emission spectra in various solvents found that both compounds produced solvent-independent spectra due to their non-polar molecules. In addition, the aggregation-caused quenching phenomenon was observed, when the emission spectra were recorded in high water fraction solvent.
期刊介绍：
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
