We have devised a novel and fluorescent chemodosimeter (ANT-Fe), possessing an anthracene scaffold as a fluorophore and ferrocene as a redox active unit for selective and sensitive detection of Cu²⁺ ions in aqueous media. Its synthesis was realized by a simple combination of two commercially available compounds, 2-aminoanthracene and ferrocenecarboxaldehyde, in one-step without required column chromatography for the purification process. The probe offers distinct properties such as aggregation induced emission, dual sensing mode of fluorometric “turn-off” and electrochemical signaling with cathodic shift, high selectivity towards Cu²⁺ ions, fast response time and low detection limit (2.5 ppb) via CN bond hydrolysis. Detection of Cu²⁺ ions by ANT-Fe adsorbed on a test paper system with the naked eye as a practical application is also successfully reported.

我们设计了一种新颖的荧光化学计量仪（ANT-Fe），具有蒽骨架作为荧光团，二茂铁作为氧化还原活性单元，用于选择性和灵敏地检测水性介质中的Cu ²⁺离子。它的合成是通过简单地将两种市售化合物2-氨基蒽和二茂铁甲醛进行简单组合而实现的，无需纯化过程即可使用柱层析。该探针具有独特的特性，例如聚集诱导发射，荧光“关断”的双重传感模式和带有阴极移位的电化学信号，对Cu ²⁺离子的高选择性，快速响应时间和通过C的低检测限（2.5 ppb）N键水解。还成功地报道了通过肉眼吸附在试纸系统上的ANT-Fe检测Cu ²⁺离子的实际应用。
