利用集电子传输型与空穴传输型为一体会增强荧光量子产率原理,将具有电子传输型的二苯乙烯基与空穴传输型的吡唑啉类衍生物合成一类新的有机荧光化合物。在吡唑啉环的1位位置连接电子传输型基团二苯乙烯基,3,5位位置用芳基衍生物取代,设计并合成了8种新的含电子传输型基团二苯乙烯基的吡唑啉类荧光化合物。分别通过一系列红外光谱、1 H-NMR谱、质谱、元素分析和荧光性能测定等检测手段进行测定确认化合物的结构。结果表明实验所合成的化合物具备荧光性能,且荧光性理想,其中所得紫外光谱最大发射波长被吸收在350nm左右,荧光最大发射波长在450nm附近,可以看出实验所合成的吡唑啉类荧光化合物是一类良好的蓝紫色荧光化合物[1]。
Using the principle of integrating the electron transport type and the hole transport type to enhance the fluorescence quantum yield principle, a new type of organic fluorescent compound is synthesized from the electron transport distyryl group and the hole transport type pyrazoline derivative . At the 1 position of the pyrazoline ring, the electron transfer group distyryl was linked and substituted at the 3 and 5 positions with aryl derivatives. Eight novel electron transfer groups, distyryl Of pyrazoline fluorescent compounds. The structures of the compounds were confirmed by a series of detection methods such as infrared spectroscopy, 1 H-NMR spectroscopy, mass spectrometry, elemental analysis, and fluorescence spectroscopy. The results show that the compounds synthesized in the experiment have the fluorescence performance and the ideal fluorescence. The maximum emission wavelength of the obtained UV spectrum is about 350 nm and the maximum fluorescence emission wavelength is about 450 nm. It can be seen that the synthesized pyrazoline fluorescent compound Is a good blue-violet fluorescent compound [1].
