Two-dimensional Cd(ii) coordination polymer encapsulated by Tb³⁺ as a reversible luminescent probe for Fe³⁺

Abstract

A new and convenient method for individual identification of Fe3+ ions by the combination of Cd-P and Tb3+@Cd-P was successfully established.

Luminescent metal–organic frameworks as optical sensors for selective sensing towards Fe3+ and Cu2+

“…The reason for luminescence quenching is that a non-luminescent ground state complex is formed between the nitrogen atoms of Fe 3+ and MOF. [83][84][85][86][87] The IISERP-MOF25 could successfully analyse Fe 2+ and Fe 3+ to achieve the purpose of separation in aqueous solutions, and the LOD towards Fe 3+ was 3.6 ppm. These results indicated that Ln-MOF could act as environmentally benign, cost-effective, scalable, and recyclable sensors.…”
