Multidimensional luminescent cobalt(ii)-coordination polymers as sensors with extremely high sensitivity and selectivity for detection of acetylacetone, benzaldehyde and Cr₂O₇²⁻

Three new ternary cobalt(ii) CPs were synthesized. 1 exhibits a 3D pcu framework, 2 possesses a 2D hcb layer and 3 is a 1D chain structure. 1, 2, and 3 can be effective luminescent probes for sensing acetylacetone, benzaldehyde and Cr2O72− ions.
