Abstract

Seven novel syringaldehyde α-aminophosphonate derivatives (1–7) were synthesized based on syringaldehyde together with different aryl amines and diethyl phosphite in a one-pot, solvent free, and catalyst free reaction. All of the obtained compounds were characterized by analysis of their ¹H NMR and ¹³C NMR, IR spectra, and FT mass spectra. The UV and fluorescence emission spectra of 1–7 were investigated in the concentration range of 0.1–250 μM. As the results, the maximum emission wavelength of 1–7 was observed between 600 and 700 nm under the exciting wavelength of 250 nm for 1–5 and 300 nm for 6 and 7. The emission intensity is the strongest at a concentration of 60 μm for 2, 3, and 5–7, 30 μm for 1, and 0.1 μm for 4.

新型丁香醛α-氨基膦酸衍生物的一锅合成及其荧光性质

以丁香醛为原料，与不同芳基胺和亚磷酸二乙酯在无溶剂、无催化剂的一锅反应中合成了7种新的丁香醛α-氨基膦酸酯衍生物（1-7）。通过分析它们的1H NMR和13C NMR、IR光谱和FT质谱来表征所有获得的化合物。在0.1–250的浓度范围内研究了1–7的紫外线和荧光发射光谱 μM。结果，在1–5的250 nm激发波长和6和7的300 nm激发波长下，观察到1–7的最大发射波长在600和700 nm之间。在浓度为60μm的情况下，2、3和5–7的发射强度最强，在浓度为30μm的1和0.1μm的4的情况下发射强度最强。
