【摘要】：以1,8-萘酐、N,N-二甲基乙醇胺、三乙烯四胺為原料,通過(guò)酰亞胺化、縮合等反應(yīng),合成一種萘酰亞胺熒光探針,并通過(guò)核磁氫譜、紅外光譜結(jié)構(gòu)表征,測(cè)定了探針在乙醇與水的混合溶液中的熒光光譜�？疾炝私饘匐x子濃度等因素的影響,對(duì)其配位機(jī)理進(jìn)行了研究。結(jié)果顯示,目標(biāo)產(chǎn)物在乙醇-水溶液中對(duì)Fe~(3+)表現(xiàn)出了專屬選擇性識(shí)別性能,在(1.87~6.53)×10~(-6)g/m L的Fe~(3+)濃度范圍內(nèi),探針熒光強(qiáng)度與Fe~(3+)濃度有很好的線性關(guān)系,線性相關(guān)系數(shù)R=0.995 3,檢出限為405.1 ng/mL。
[Abstract]:A naphthalimide fluorescence probe was synthesized by imidization, condensation and other reactions from 1: 8 naphthalic anhydride, N- dimethyl ethanolamine and triethyltetramine. The fluorescence probe was characterized by NMR and IR spectra. The fluorescence spectra of the probe in the mixed solution of ethanol and water were measured. The influence of metal ion concentration on coordination mechanism was investigated. The results show that the target product has the exclusive selective recognition performance for Fe~ (3) in ethanol-aqueous solution. The fluorescence intensity of the probe has a good linear relationship with the concentration of Fe~ (3) in the range of (1.87 ~ (-6) 脳 10 ~ (-6) g / mL) Fe~ (3). The linear correlation coefficient (RV) is 0.995 3, and the detection limit is 405.1 ng/mL..
