A new class of thermo- and solvatochromic metal–organic frameworks based on 4-(pyridin-4-yl)benzoic acid
Using 4-(pyridin-4-yl)benzoic acid, 44pba (1) as a ligand, two new metal-coordination networks [Co4(44pba)8]n·[(DMF)3·(EtOH)0.25·(H2O)4]n (2) and [Ni4(44pba)8]n·[(DMF)3.5·(EtOH)·(H2O)1.5]n (3) were synthesized by solvothermal methods and structurally characterized. Compounds 2 and 3 are isostructura...

| description | Using 4-(pyridin-4-yl)benzoic acid, 44pba (1) as a ligand, two new metal-coordination networks [Co4(44pba)8]n·[(DMF)3·(EtOH)0.25·(H2O)4]n (2) and [Ni4(44pba)8]n·[(DMF)3.5·(EtOH)·(H2O)1.5]n (3) were synthesized by solvothermal methods and structurally characterized. Compounds 2 and 3 are isostructural but differ in their solvent content. Each is a 2D-network which forms a spiral parallel to [001], giving rise to three distinct large channels, accounting for some 47% of the unit cell volume. Both 2 and 3 display water-induced phase transformations with chromotropism, which has been confirmed by TGA and XRPD analysis. Solvatochromism in 2 is also evident with crystals exhibiting a range of colours depending on the solvent included. This phenomenon has been characterized using TGA, XRPD and UV-vis spectrophotometry. |
