Design and synthesis of a stable multifunctional photoluminescence sensing material for rare earth ions from a 2D undulating Cd-coordination polymer

A new type of 2D light-emitting coordination polymer [Cd(H2L)(H2O)(2)]n (CP1) (H4L=3,5-bis(3,4-dicarbox-yphenyl)pyridine) was successfully constructed, which shows stability in a wide range of pH solution. More importantly, this material is a multifunctional luminescence sensing material which can become a good candidate for La3+/Eu3+/Tb3+/Dy3+ ions selective sensing with lower detection limits.

Automated summary

The new 2D light-emitting coordination polymer CP1 exhibits stability in a wide range of pH solutions and serves as a multifunctional luminescence sensing material. It shows potential for selective detection of La3+/Eu3+/Tb3+/Dy3+ ions with lower detection limits.
