Coordination polymers (CPs) are emerging crystalline materials constructed from metal entities and organic ligands through coordination bonds, containing infinite coordination units in one, two, or three dimensions. Here an overview is given of recent structural research based on seven cyclohexanepolycarboxylates (CHPCs), namely cyclohexanecarboxylate, 1,x-cyclohexanedicarboxylate (x = 2, 3, or 4), 1,3,5-cyclohexanetricarboxylate, 1,2,4,5-cyclohexanetetracarboxylate and 1,2,3,4,5,6-cyclohexanehexacarboxylate, showing the effects of the conformation transformation and auxiliary ligands on the dimensionality and the geometric topology of the assemblies generated. The applications of these CPs as platforms for molecular adsorption, luminescent sensing, magnetism, and catalysis are also briefly discussed.
