AbstractWe report dynamic, multiple single-crystal to single-crystal transformations of a coordination network system based on a semirigid molecule, TCPSB = 1,3,5-tri(4′-carboxyphenylsulphonyl)benzene, which nicely balances shape persistence and flexibility to bring about the framework dynamics in the solid state. The networks here generally consist of (1) the persistent core component (denoted as CoTCPSB) of linear Co II aqua clusters (Co-O-Co-O-Co) integrated into 2D grids by 4,4′-bipyridine and TCPSB and (2) ancillary ligands (AL) on the two terminal Co II ions-these include DMF (N,N′-dimethylformamide), DMA (N,N′-dimethylacetamide), CH 3CN, and water. Most notably, the ancillary ligand sites are highly variable and undergo multiple substitution sequences while maintaining the solid reactants/products as single-crystals amenable to X-ray structure determinations. For example, when immersed in CH 3CN, the AL of an as-made single crystal of CoTCPSB-DMF (i.e., DMF being the AL) is replaced to form CoTCPSB-CH 3CN, which, in air, readily loses CH 3CN to form CoTCPSB-H 2O; the CoTCPSB-H 2O single crystals, when placed in DMF, give back CoTCPSB-DMF in single-crystal form. Other selective, dynamic exchanges include the following: CoTCPSB-DMF reacts with CH 3CN (to form CoTCPSB-CH 3CN) but NOT with water, methanol, ethanol, DMA, or pyridine; CoTCPSB-H 2O specifically pick outs DMF from a mixture of DMF, DMA, and DEF; an amorphous, dehydrated solid from CoTCPSB-H 2O regains crystalline order simply by immersion in DMF (to form CoTCPSB-DMF). Further exploration with functional, semirigid ligands like TCPSB shall continue to uncover a wider array of advanced dynamic behaviors in solid state materials. © 2011 American Chemical Society.
