Abstract

In this investigation, a nonconjugated fluorescent polyamide with piperazine and valerolactam moieties (PAM–PV) has been synthesized by the modified Ugi polymerization using 1,4-bis(3-aminopropyl)piperazine, levulinic acid, and 1,4-bis(3-isocyanopropyl)piperazine as monomers. In the polymerization, the special construction of levulinic acid leads to the formation of valerolactam on PAM–PV chains via the Mumm rearrangement. PAM–PV shows a strong fluorescence emission at 428 nm due to the intramolecular aggregation of piperazine and valerolactam moieties along the backbone. Impressively, PAM–PV can specifically detect NO2 ions via static quenching with a linear range of 10–6–10–5 M and a detection limit of 0.6 μM (0.0276 mg/L), which was far less than the minimum allowable concentration of 3 mg/L for NO2 in drinking water specified by WHO. Furthermore, the several common anions and cations have no interference effects on the specific detection of PAM–PV to NO2 ions. The quenching mechanism of NO2 and PAM–PV by FTIR, UV, and 1H NMR measurements indicates that the strong electrostatic interaction between NO2 and PAM–PV makes the macromolecular chains more relaxed and outstretched, leading to a formation of a nonfluorescent complex. Moreover, the practical detection of NO2 in the three water bodies, sauerkraut, and ham sausage and the fabrication of a portable detecting paper to NO2 ions were conducted in this experiment.

改性Ugi反应制备哌嗪和戊内酯结构的荧光聚酰胺及其对NO2 -离子的特异性检测
以1,4-二(3-氨基丙基)哌嗪、乙酰丙酸和1,4-二(3-异氰丙基)哌嗪为单体,采用改性Ugi聚合法制备了哌嗪-戊内酯非共轭荧光聚酰胺(PAM-PV)。在聚合过程中,乙酰丙酸的特殊结构导致PAM-PV链上通过Mumm重排形成戊内酯。PAM-PV在428 nm处表现出较强的荧光发射,这是由于哌嗪和戊内酰胺在分子内沿主链聚集。令人印象深刻的是,PAM-PV可以通过静态淬火对NO2 -离子进行特异性检测,线性范围为10-6-10-5 M,检出限为0.6 μM (0.0276 mg/L),远低于WHO规定的饮用水中NO2 -的最低允许浓度3 mg/L。此外,几种常见的阴离子和阳离子对PAM-PV对NO2 -离子的特异性检测没有干扰作用。FTIR、UV和1H NMR对NO2 -和PAM-PV的猝灭机理进行了研究,结果表明NO2 -和PAM-PV之间的强静电相互作用使大分子链更加松弛和伸展,从而形成非荧光络合物。并对酸菜、火腿肠三种水体中的NO2 -离子进行了实际检测,制作了便携式NO2 -离子检测纸。
