A water-stable dual-responsive Cd-CP for fluorometric recognition of hypochlorite and acetylacetone in aqueous media.

One novel cadmium(II)-coordination polymer [CdL(datrz)(HO)] (CP 1) is controllably synthesized by surmising the astute combination of semi-rigid tricarboxylate acid 4-(2',3'-dicarboxylphenoxy) benzoic acid (HL) and auxiliary ligand 3,5-diamino-1,2,4-triazole (datrz). Structure analysis shows that CP 1 has a two-dimensional (2D) layer structure with a 5-nodal (4) (4·6) (4·6·8) (4·6) (4·6·8) topology. Further investigations reveal that CP 1 shows superordinary water stability and good thermal stability.
