Herein, a red fluorescent and colorimetric probe (NDI-Py) based on naphthalene diimide was designed and synthesized, which exhibited rapid response, high sensitivity and selectivity towards copper ions, and the detection limit was as low as 0.97 μM in solution. Furthermore, NDI-Py demonstrated a strong red emission in the aggregated state because of its non-planar structure. Thus, it can act as a test strip to conveniently monitor copper ions with the detection limit as low as 2.0 μM.
在此，设计并合成了一种基于萘二酰亚胺的红色荧光和比色探针（NDI-Py），它对铜离子表现出快速响应、高灵敏度和选择性，在溶液中的检测限低至0.97 μM。此外，由于其非平面结构，NDI-Py在聚集态下表现出强烈的红色发射。因此，它可以用作测试条，方便地监测铜离子，检测限低至2.0 μM。
