| 摘 要： | 将N-(4-甲基苯基)-N′-甲基脲与中间体三氨三羰基合铬反应,合成了一种新型的红外化学传感器分子——N-(4-甲基苯基)-N′-甲基脲三羰基铬;利用元素分析、红外光谱、核磁共振波谱及电子轰击质谱分析了其组成和结构;采用傅立叶变换红外光谱初步研究了该金属羰基化合物对氟离子的红外识别与传感性能.结果表明,在质子型介质乙醇中,随着氟离子的加入,该金属羰基化合物的特征吸收峰向低波数方向显著偏移;其对氟离子的红外识别检测下限可达10-6 mol.L-1. |

| Abstract: | A novel infrared（IR）chemosensor molecular,N-（4-methylphenyl）-N′-methyl urea chromium tricarbonyl,was synthesized by treating N-（4-methylphenyl）-N′-methyl urea with（NH3）3Cr（CO）3.The composition and structure of as-synthesized product were analyzed by elemental analysis,IR spectrometry,nuclear magnetic resonance spectroscopy and electron ionization mass spectrometry.A Fourier transform infrared spectrometer was used to preliminary examine the recognition and sensing properties of as-synthesized product for fluoride anion.Results indicate that the characteristic absorption peaks of as-synthesized metal carbonyl compound remarkably shift towards low wavenumbers upon the addition of fluoride to its solution in protic medium like ethanol.Besides,its IR recognition detection limit for fluoride anion in ethanol reaches as much as 10-6 mol.L-1. |
