A bimodal 2D silver coordination polymer: Turn-on sensing of CdII and sensitization of lanthanide ions

• The Ag-complex based on 5-(4-carboxyphenyl) nicotinic acid was obtained.
• Complex 1 provides an ideal luminescence sensor for selective probing Cd2 + ion.
• Complex 1 can serve as an antenna for sensitizing the visible-emitting of the lanthanide ions in solution.

The new transition metal coordination polymer, namely [Ag(Hcpna)]n (1) (H2cpna5-(4-carboxyphenyl) nicotinic acid) has been synthesized under hydrothermal conditions and characterized. Interestingly, when this compound was immersed in the different metal ion solutions, it shows highly selective sensing for Cd2 + based on significant luminescence enhancement. What's more, the compound 1 can serve as an antenna for sensitizing the visible-emitting of the lanthanide cations to exhibit their characteristic emissions in solution.
