A novel fluorescent probe possessing anthracene with an indole unit was designed and synthesized to detect chromium(III) ions (Cr3+) with high sensitivity and selectivity. The probe was synthesized in one step by mixing two commercially available chemicals, 2-aminoanthracene and Indole-5-carboxaldehyde. The probe molecule (ANT–In) demonstrates distinct properties, for instance, “turn-on” fluorescence response, high sensitivity and selectivity in less than one minute, and low detection limit (0.2 µM) via hydrolysis of the C = N bond. Additionally, the probe ANT–In was successfully used to identify the presence of chromium(III) ions in real water samples.

用于检测真实水样中铬 (III) 离子的蒽和吲哚基荧光探针
设计并合成了一种具有吲哚单元的蒽的新型荧光探针，以高灵敏度和选择性检测三价铬离子(Cr 3+ )。该探针是通过混合两种市售化学品 2-氨基蒽和吲哚-5-甲醛一步合成的。探针分子 (ANT–In) 表现出独特的特性，例如，“开启”荧光响应、不到一分钟的高灵敏度和选择性，以及通过C = N 键的水解实现的低检测限 (0.2 µM)。此外，探针 ANT–In 已成功用于识别实际水样中铬 (III) 离子的存在。
