Abstract：
Aniline compounds, as a class of widely used but highly toxic chemical raw materials, are increasingly being released and accumulated in the environment, posing serious threats to environmental safety and human health. Therefore, developing detection methods for aniline compounds is of particular significance. Herein, we synthesized the fluorescent third monomer cyano-stilbene epoxide M and ternary copolymerized it with carbon dioxide (CO2) and propylene oxide (PO) to synthesize carbon dioxide-based polycarbonate (PPCM) with fluorescence recognition functions, as well as excellent performance, for the first time. The results revealed that the PPCM fluorescent probe exhibited typical aggregation-induced luminescence properties and could be quenched by aniline compounds. The probe presented anti-interference-specific selectivity for aniline compounds, and the detection limit was 1.69 × 10-4 M. Moreover, it was found to be a highly sensitive aniline detection probe. At the same time, the aniline biomarker p-aminophenol in urine could also be detected, which could expand the potential applications of polymers in the fluorescence-sensing field.
摘要：
苯胺化合物,作为一类用途广泛但毒性大的化工原料,越来越多地在环境中释放和积累，对环境安全和人类健康构成严重威胁。因此,开发苯胺类化合物的检测方法具有特别重要的意义。在这里，我们合成了荧光第三单体氰基-二苯乙烯环氧化物M，并将其与二氧化碳(CO2)和环氧丙烷(PO)三元共聚，合成了具有荧光识别功能的二氧化碳基聚碳酸酯(PPCM)，以及出色的性能，第一次。结果表明，PPCM荧光探针具有典型的聚集诱导发光特性，可以被苯胺化合物猝灭。该探针对苯胺化合物具有抗干扰特异性选择性，检出限为1.69×10-4M。它被发现是一种高度灵敏的苯胺检测探针。同时,还可以检测到尿液中的苯胺生物标志物对氨基苯酚，拓展了聚合物在荧光传感领域的潜在应用。
