A new 2D cadmium chloride network with 2-aminopyrimidine displaying long lifetime photoluminescence emission

The hydrothermal reaction of CdCl2 with 2-aminopyrimidine in water yields a 2D metal–organic coordination framework [CdCl2(PymNH2)] (1) (PymNH2 = 2-aminopyrimidine). This compound consists of Cd2(μ-Cl)2 corner-sharing chains bridged by PymNH2 through the endocyclic ring nitrogen atoms. Interestingly, this polymer exhibits long lifetime photoluminescence emission at room temperature in the solid state with long lifetimes decay.

► We have designed and studied a Cd-polymer of interesting structure and potential applications.
► No examples of polymers with this ligand and exhibiting luminescence properties exist.
► This 2D-polymer has shown long lifetime photoluminescence emission in solid state.
► The emission lifetime that fits a double-exponential decay with values of 0.12 and 2.89 ms.
