摘要

The new transition metal coordination polymer, namely [Ag(Hcpna)](n), (1) (H(2)cpna=5-(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.
