| Abstract: | Four new bimetallic coordination polymers (CPs), {M[Pt(CN)2(5,5'-dcbpy)]・4H2O}n(M = Mg^[2+], Ca^[2+], Sr^[2+], Ba^[2+]; 5,5'-H2dcbpy = 5,5'-dicarboxy-2,2'-bipyridine) were synthesized using four alkaline-earth metal ions and a Pt(II)-diimine metalloligand [Pt(CN)2(5,5'-H2dcbpy)]. All four CPs are isomorphous with the Zn complex, {Zn[Pt(CN)2(5,5'-dcbpy)]・4H2O}n, which exhibits effective metallophilic interactions between Pt(II) ions. These CPs exhibited colourful thermochromic behaviour and solid-state solvatochromic-like behaviours when suspended in various solvents. Thermogravimetric analysis and vapour-adsorption measurements revealed that the CPs can reversibly adsorb water and MeOH vapours. The emission energy of the triplet metal-metal-to-ligand charge-transfer (3MMLCT) state varied markedly upon guest adsorption/desorption. The chromic and vapour-adsorption properties of these CPs depend strongly on the cross-linking M^[2+] ions. |
