Hydrazine, a compound known for its toxicity to human health and the environment, finds extensive use across various industries, potentially contributing to several diseases. Hence, the accurate measurement of hydrazine levels is paramount. This study introduces three new aggregation induced emissive luminogens (AIEgens) GBY-7, GBY-8, and GBY-9 crafted from benzofuran infused with a dicyanovinylidene group, tailored specifically for hydrazine monitoring. These probes feature a D-π-A core with a rotor, providing an optimal fluorescent base. Additionally, a potent electron-attracting nitrile group aids in the nucleophilic addition of N2H4 to form a hydrazone, blocking the intramolecular charge transfer (ICT) process and inducing optical signal modulation. Notably, luminogens GBY-8 and GBY-9 exhibit high selectivity in detecting hydrazine amidst competing amine-based compounds, showcasing detection limits of 0.00020 mM and 0.0043 mM, respectively.

设计新型苯并呋喃衍生 AIE 探针：用于肼检测的双模式荧光关闭和肉眼颜色变化


肼是一种对人类健康和环境具有毒性的化合物，广泛应用于各个行业，可能导致多种疾病。因此，准确测量肼含量至关重要。本研究介绍了三种新型聚集诱导发光发光体 (AIEgens) GBY-7、GBY-8 和 GBY-9，它们由注入二氰基亚乙烯基基团的苯并呋喃制成，专为肼监测而定制。这些探针具有带转子的 D-π-A 核心，可提供最佳的荧光碱基。此外，有效的吸电子腈基团有助于 N2H4 的亲核加成形成腙，从而阻止分子内电荷转移 (ICT) 过程并诱导光信号调制。值得注意的是，发光剂 GBY-8 和 GBY-9 在检测竞争性胺基化合物中的肼时表现出高选择性，检测限分别为 0.00020 mM 和 0.0043 mM。
