Fast capture and separation of, and luminescent probe for, pollutant chromate using a multi-functional cationic heterometal-organic framework

摘要

We present one 3D cationic MOF (1-C1O_4), which exhibits high thermal stability and strong alkali resistance. More importantly, it displays fast, selective capture of, and acts as a luminescent probe for, pollutant CrO_4~2 by anion exchange. Additionally, 1-ClO_4 exhibits interesting slow magnetic relaxation behavior at low temperature.
